I have a VPS with Ples. I did the domain configuration and etc. I go to webmail.mydomain.com and login, when I send email to email#hotmail.com the recipient receives it. When I send it to email#gmail.com it returns an error.
The error is as follows:
This is the mail system at host xxxxxxxxxxxxxxxxxxxxxxx.

Why is this happening?
Because Gmail doesn't just accept emails from any domain without autheticating them.
Research keywords SPF, DMARC & DKIM. They will lead you in the right path.

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?

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,
TheJohnny
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.

how to fix this problem?
As the error states, The IP address sending this message does not have a PTR record setup, so you need to set the PTR record for 185.124.86.138 (it is quite usual that receiving mail server requires this). Reverse DNS is controlled by whoever "owns" the IP address, so you should probably contact Bilgehosting to set the record for you)
I know that this question is not strictly related to coding, but I'm trusting the knowledge of this community to solve this and I thought it could still interest many people to know how to face this problem.

Does anyone know what's going on here?
I am trying to send from a normal gmail account, straight from the web browser. It looks like I get this error only when I send e-mails to this specific domain, although we've been e-mailing in the past with no issues at all.
Thank you!
