Multi Domain Mail Server

itbcp

Hi guys,
i am happy to use aapanel for my all domains.
i want to install mail server too. I've read most of the discussions regarding mail server. I am confused.

here is my questions.

once i install mail server from app store, can i use it for multi domains?
smtp and ssl is only for one domain? or i can use smtp under each domain?

or all domains is going to use same smtp to send e-mails? (smtp.maindomain.com)

if there is only one smtp, will i have spam box issue with e-mail receivers?

server is ubuntu 20.04
vps provider is aws.
aapanel 6.8.15

if you guide me, i am eager to learn.

itbcp Good question, although I'm using it for some domains that I've been migrating little by little to my VPS using aaPanel I confess that there is little documentation about the questions are great.

Following this topic to be aware of the return as well.

itbcp yes, i'm also using multiple domains on the same mail server.
smtp & ssl is separately for each domain.
eg, 1st domain is example.com, smtp & incoming mail server = mail.example.com
2nd domain is example2.com, smtp & incoming mail server =mail.example2.com
you can also use 1 smtp on all the domains, just you might receive some error logs, but it still work.

1stly, you need to create your domain, then point dmarc and so on to your aapanel. 2ndly apply ssl for the domain.
lastly you might need to make some changes by referring to this post, and your mail server should be working fine.
Repeat the steps again if you would like to add multiple domains in the same server.

good evening
I have a more complicated problem.
I have several mail domains.
accepts and receives correctly from the mail app bar.
but if I post an email on any of my sites. the letter comes from the domain which I have already deleted long ago.
tried to send from another site, the same thing.
the mail application sends from sites only to one address, which is not in it.

please help me how to fix it. how to make sure that from the site procrm.uz go to the mail info@protcrm.uz, and from the site procrm2.uz to info@procrm2.uz
