Is there a way to configure multiple mail domains behind the astaro?
We have two mail servers at my company that support multiple domains. The first server is our company server, and it sits behind Astaro on our primary domain. The second server is a Mail Blast server and is primarily used for outbound sending of mails. However, we send this email on a separate domain and need to capture bounce messages as well as pass RDNS checks. So I have three main problems:
1) How do I get the SMTP banner to read from the mail server and not the Astaro gateway (Can I just leave the Astaro SMTP banner blank?
2) How do I tell Astaro that all mail sent to domain A goes to server A and all mail sent to domain B goes to server B, because with server B sitting outside of the Astaro, all the spam send to user1@domainB.com gets forwarded to user1@domainA.com. Unfortunately, because domainB.com passes all the spam checks, the original spam message is still getting through.
3) Why is it that when I'm going through Astaro with the server B, my Reverse DNS fails, but when it's outside the Astaro, it works fine? (Using MXToolbox). Server A has no problems at all.
Any suggestions or input?
TIA!
