hello,
I own multiple website, each website need email account, so we create them.
We set first mail.domain1.com for the first website. Work well, we set the ptr to mail.domain1.com too.
For the next websites, we did the same, we set mail.domain2.com and mail.domain3.com, the ptr is only the thing we can’t change because it allow only one domain, so we keep it to mail.domain1.com.
The problem is that when we send email from domain2 & domain3 with their respective mail.domain2.com and mail.domain3.com smtp and imap settings we are identified has spam on gmail.
So we set domain2 & domain3 with mail.domain.com for both, then we are no more identified has spam by gmail.
How can you explain that, how can we do ?
It is really necessary to create mail.domain2.com and mail.domain3.com when mail server was already set first to mail.domain.com ?
I hope to have an answer… ? This poor man don’t have one : Setting up multiple mail servers? - #2 by subzero
