I made an SMTP server in microsoft server 2016. But when i go to send mail through powershell to an email address. The mail goes to queue or bad list. It give me the error:

Anyone know what i am doing wrong? I have an a record for mail pointing to the servers ip.
Thanks,
request removal on the given url
don't send too much email to 1 provider at once ( send 5-10 then pause until your spam-score decreases, then may be more ... )
Your IP is assigned from a pool of addresses of a consumer ISP. You can request to be removed from the whitelist, but likely it will end up there again as very likely is abused by spammers.
inetnum: 90.255.32.0 - 90.255.63.255
netname: VODAFONE-DYN-IP
descr: Dynamic IP Addresses
descr: Vodafone Consumer Broadband
You can attempt to use a proxy to mask your IP hoping that the public IP will not be blacklisted, or you can attempt to reset the router in order to get assigned another public IP which is not blacklisted. However, the real solution would be to contact your ISP and request to have assigned a static IP address, but likely this is available for business contracts only or you have to pay an additional fee for it.

I have migrated my website and the email records to a new server (other provider). Everything was ok except that now when I want to send a message from my email (my email direction is the same), one of my clients can not receive my messages. I chatted with my client and his mails are ok, he is receiving mails without problems, as he said.
I reported the problem to my Hosting provider and they have changed the mail Exchanger from remote to local but it didn't finish with the problem. Someone knows what could be happening?
This is part of the message that appears:

Thanks,
I found the solution. The problem was that the other websites (the domains of my client) are inside my server and in the Email Routing section (it is in the Cpanel) of those websites, the domains were targeted as "Local server" or not targeted. Despite it, the email server for those domains don't were in my server then the system was confused. I just changed the target to "Remote servers" for both domains (the domains of my client) and the problem disappear.
I hope this explanation could be useful for other developer.
Anyway thank you,

I have a website with a web form that is hosted with a third party. I'm having trouble with their server config/architecture and wanted to confirm a few things and show the mail headers I am receiving.
I know that I must explicitly set my mail to send through an outgoing mail server and port which I have specified (this is in order for the mail to send, it will not be sent if not sent through the SMTP server).
Upon setting the SMTP server and port here is the mail header:

Focusing on the Authentication-Results the (sender IP is 213.171.216.60) which is definitely the correct outgoing SMTP server. However the the spf result is spf=softfail.
After doing some research it was suggested that
The Return-Path header is empty. This means that during the SMTP
conversation, the MAIL FROM command did not specify an email address
where bounces are sent. It is the domain from this email address that
SPF tests. If there is no email address, a softfail will result.
Is this referring to the smtp.mailfrom field in the Authentication-Results which is set to a value of test#hotmail.co.uk in the example above?
I believe I have done what is required to implement SPF:
(1) I have set the SPF record in the domain's DNS zone
v=spf1 a ip4:213.171.216.0/24 mx -all
Now the confusion arises here. When someone else's mail server receives a message claiming to come from that domain, then
(2) the receiving server can check whether the message complies with the domain's stated policy
How does hotmail's receiving mail server for example do this check? because if I set a Return-Path of hello#fun-booths.co.uk then this results in spf=pass. Just to be clear www.fun-booths.co.uk is the domain being used.

This leads me on to my final questions - Is it true that the Return-Path must be set to a real email address on the site domain (www.fun-booths.co.uk), or mail will not send?
Because I have set up the mailbox hello#fun-booths.co.uk, however it seems even when I delete the mailbox that this still results in an spf=pass. It seems that in other words that not having a real email address on the domain, and instead just setting the Return-Path to hello#fun-booths.co.uk without the mailbox existing will result in an spf=pass. Should this be the case?
Is the email #fun-booths.co.uk set in the Return-Path used to determine the domain for the SPF checks?
Finally in the quotation above that mentions the SMTP conversation, is the MAIL FROM command referencing the smtp.mailfrom field in the Authentication-Results?
SPF Checks are always done with the envelope sender (MAIL FROM:) - smtp.mailfrom in your case. In the first mail you have test#hotmail.co.uk as envelope sender, but your server is not listed in the SPF record for hotmail.co.uk, and since that record has ~all as the last mechanism you get a Softfail.
In the second mail the envelope sender is hello#fun-booths.co.uk, so it's the SPF record for fun-booths.co.uk that is being used in that check.
So you should use a fun-booths.co.uk address as your envelope sender.
Depending on how you send mail from the web form there are different ways to control the envelope sender, but it may be that value of Return-Path is used as the envelope sender.
There don't have to be a mail-box for the envelope sender for the SPF to work, since SPF normally only look at the domain part of the address, but if the mail bounces somewhere in the process, the bounce message will normally be sent the the envelope sender, so it's a good idea to keep the mailbox for that address.
I have hosting through hostgator and cPanel. I have multiple domains. I want to set up emails for a domain. I do so in cPanel creating a user #the-domain-name.com, giving it a password, and email is created.
It has a webmail access at www.the-domain-name.com/webmail and the username and password work to get in. That is fine to log in that way (although I'd like to use Mac's Mail app to do so and set up to work, having difficulty there also).
The issue is that the email address can send out messages, but when I try to send a message to that email through another address, say my Gmail account, I get a "Delivery Status Notification (Failure)" email immediately after saying this:
Delivery to the following recipient failed permanently:
mynewuser#the-domain-name.com
Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the server for the recipient domain the-domain-name.com by the-domain-name.com. [104.255.196.241].
The error that the other server returned was:

I substituted all the real emails and domain name out with generic ones.
How can this be fixed to where I am able to both SEND and RECEIVE from the new cPanel email, and ultimately, how can I do so with Mac Mail??
Thanks
Handling, sending/receiving your emails with cPanel is very easy.
As the error you get says: 550 No Such User Here , double check your email account name.
Also, check the mail log file, which on a WHM/cPanel server I think is: /var/log/exim_maillog
Of course you can always contact your host for help. The last time I had problems with my cPanel email accounts, I contacted my host and it turned out that my custom exim config file was overwritten by cPanel Exim updates.
We recently implemented a DMARC record for our domain:
"v=DMARC1; p=quarantine; pct=100; rua=mailto:me#mydomain.com"
(quarantine 100% of non-authenticated emails and send aggregate report to "me")
We use a third-party vendor to issue invites. The vendor sends email from invites#invites.vendordomain.com which is then sent through a mail relay "smtp3.mailrelaydomain.it". I also know that the mail relay uses a single ip address.
That address is included in our SPF record:
"v=spf1 ...[SNIP reference for other mail servers SNIP]... ip4:[ip address for the mail relay] ~all"
When I send an invite using the vendor's service, the message is quarantined.
When I view the aggregate DMARC report I see that the invite:
is recognized as being from an SPF-Authorized Server
passes raw SPF authentication for the sender's domain (invites#invites.vendordomain.com")
passes raw DKIM authentication for the mail relay domain (smtp3.mailrelaydomain.it)
Fails DMARC authentication for both DKIM and SPF for mydomain
Here is a sample headers from an invite.

I believe the issue is related to the from domain in the message not matching the domain for the message envelope; however, the vendor is unable to change their settings (i.e., envelope will always be from the vendor domain) so any chance of this working with DMARC will have to come from my end.
Knowing that the SPF record can (and does) identify the invite as being from an SPF-Authorized Server, are there any other settings or records I can add to also ensure DMARC authentication for invites from the vendor?
Having read several online articles and "DMARC -spf and DKIM record queries" I suspect I am out of luck, but need to ask the question plainly/specific to my situation just to be sure.
Thanks
You are correct, you are out of luck unless the vendor can change something. What is failing is Identifier Alignment - https://www.rfc-editor.org/rfc/rfc7489#section-3.1 - because what is being authenticated (invites.vendordomain.com via SPF) does not align to the domain the user sees (me#mydomain.com) and the message then, correctly, fails DMARC.
There are three options:
Stop sending with a From: header of your domain at the vendor; you can still use a Reply-To: header with your own address.
Have the vendor align the mail from to your domain. If they don't do this they can't pass DMARC, and at some point they will want to pass DMARC or people will find other solutions. You can have them send with an envelope from of vendorname.mydomain.com and you can set up an MX for that subdomain that points to them to support bounce processing. This has been BCP for a while.
Have the vendor sign with DKIM and us an aligned DKIM signature. This is also best common practice. You only need SPF or DKIM to pass, and DKIM passes are more valuable (because they survive forwarding in many cases) than SPF, so this is the option I would personally prioritize if I were you.
Back in like 2012 and 2013 a lot of vendors pushed back against both of these options, but I honestly haven't seen a vendor in a long time (I spend 100% of my day job on DMARC) that won't support at least aligned DKIM.
I am having problems sending an email from one email address to another on my domain. I am using a shared server. I use weather software which automatically constructs and sends the email message. I have omitted the host, domain and IP info and replaced them like so: host= example.co.uk, domain = mydomain.co.uk .
The situation is I run a mail group using email address (weatherinfo#) and some users in the group set auto-responders. Therefore to prevent these from going to the whole group the email is sent from a different address (reports#) to weatherinfo# with the reports# address receiving the auto-responder messages.
I am getting the following message from the mail delivery system when trying to send the email to weatherinfo# from report#:
This is the mail system at host mailauth.example.co.uk.

Why is this message being rejected?
Is this being caused by my software or the server?
If it is the software what does the developer need do to fix it?
If it is the server what should I ask my host to do to overcome this problem?
The server says, your header is wrong, so I'd search the problem within your software.
If it isn't just a missing whitespace in your post, the header field "Recieved" isn't folded as specified in RFC 2822: 2.3.3 Long Header Fields causing two invalid headers starting with "by" and "for". Correct would be:
Received: from LAPTOP (helium.example.co.uk [IP Address])
by mailauth.example.co.uk (Postfix) with ESMTPA id 88002C306D

Also I see that there are two Message-id headerfields. I do not know whether this is allowed or not.
I would always do tests with telnet (or putty/raw) in such a case and try with several heder fields skipped or modified so you can break it down to the header field your mail server is complaining about.
