I have been changing my mailing addresses from "example.com" to sub domains - say "mail.example.com" to configure no-reply addresses there. I use "sendmail -f noreply#mail.example.com" to send emails making sur ethe Return-Path is correct. My mail delivery chain looks as follows:
SENDING SERVER --> relay_server --> gateway out
For unknown to me reason when my email reaches the gateway that sends out, I see that the "from" address is already altered in the postfix log file to "noreply#example.com". This is also what I see in the detailed message log when it reaches its destination.
I have seen similar topics over here, but I made a step ahead and checked that I use the "-f" sendmail switch.
Any clues?
After the entire weekend of troubleshooting this I eventually found the reason:
http://www.postfix.org/postconf.5.html#masquerade_domains
plus restart of all postfix-related deamons (postfix, dkim and all that) helped.

I've successfully set up a mail server using iRedMail on Ubuntu 20.04. While testing my server, https://www.mail-tester.com/ reported only one problem - Your message is not signed with DKIM.
The fact is I've already set the DKIM entry in my DNS settings, but still I get the same error, thus my emails end up in the spam folder.
What am I doing wrong?

redirect all incoming e-mail on domain to one specific e-mail address
I have a domain: example.com
and one e-mail: info#example.com
i would like to receive all e-mail what it got in my domain:
example#example.com
nospam#example.com
asdasdasd#example.com
[any random character]#example.com
I don`t want to create these e-mails one by one.
I`am using gmail (apps.google.com)
btw: my main goal to have different e-mail for different website and example+slug#example.com trick is not working because lots of website filter + letter.
This may work for you. Don't create the accounts, just set the catchall

I've been seeing email that's not directly addressed to me land up in my inbox.
My email is something#domain.com, the emails that are delivered are like something+anything#domain.com. After seeing these, I tried other suffixes after the + symbol and all of them land up in my inbox. Does anyone know why that is the case? What happens if someone else registers one of the addresses like something+1#domain.com.
I saw this reliably work for both gmail and outlook, I'm curious to know why that is the case? Is there is a technical reason why mailservers drop off these suffixes.
I'm not sure if StackOverflow is the best place for this question, please move this to another site on the network which may be a better fit if that is the case.
This is called sub-addressing. + part is treated for filtering and all.You can read about it on wiki with page title Email Address.
Also known as plus addressing ortagged addressing. Some mail services support a tag appended to the local part, such that the modified address is an alias to the unmodified address. For example, the address joeuser+tag#example.com denotes the same delivery address asjoeuser#example.com.

I've VPS.
I installed postfix and what is necessary for mail server.
(I've used this as a guide: https://www.digitalocean.com/community/articles/how-to-install-postfix-on-centos-6 )
then, I configured my DNS as recomended. (this is my configure http://t1308.hizliresim.com/1d/7/r834r.png)
But there's still problem that: my mails are going to the spam directory? why? what should I do?
I've checked banlists and there's no problem about black lists.
Any idea? How can I solve this problem?
To see if your mail server has a glaring problem that would cause other mail servers to think it's a spammer, try sending a message from your mail server to check-auth#verifier.port25.com. This service will do a bunch of checks, and you'll get a report back with ton of information, such whether or not your mail server's DNS is setup correctly, whether your mail server's IP is on any black lists, if you have a problem with your SPF records, etc.
I don't know much about the setup side, but several other factors could cause it to hit spam folders. Try removing one possible cause at a time until the email works.
replace all the content with pure text (no $, !'s or large numbers)
send from a different email address
send to a different email address on a different domain
If any of those fix your problem, you should have it narrowed down to the cause, which will help the rest of us to give more targeted answers. If those things don't make a difference, then it is most likely in your setup.

Here is the situation, we have a linux web server that runs Plesk and I need a way to intercept emails sent to and from the server. Plesk uses qmail to send and receive emails.
We have sorted the receiving emails problem by adding a mailgroup to each email address that includes an "archive#" address. Then we use a PHP script to read the "archive#" mailbox and puts the emails into a MySQL database.
My problem at the moment is how to capture the messages sent from the server. Has anyone had any experience in doing this?
Thanks
Peter
this can be done via QUEUE_EXTRA (http://www.google.com/search?q=queue_extra), for which you need to recompile qmail. some hints on doing this on plesk here (http://translate.google.com/translate?hl=en&sl=pt&u=http://www.maglione.com.br/artigos/artigostecnicos/pleskqextrahowto).
