My company consists of two independent divisions. For our clients, they are actually two different companies, although they employ the same people (mail users), and each company has its own website and domain (for example, OurFund . com and OurDelivery . com).
Now the mail is set up one for all on the domain OurFund and it is very inconvenient. Customers are confused by the mail address, and employees are confused trying to figure out which division a particular email was sent to.
We have Axigen 10.3.3.50 installed on the Ubuntu 22.04 server. There are two network interfaces configured with IP XXX.XXX.100.001 and XXX.XXX.100.002 . The second interface is virtual.
Each of the domains has its own separate DNS zone and for them issued their own wildcard SSL certificates.
I put MX records in DNS for each domain separately, added the second domain in Axigen and configured for each of the IP addresses their own Listeners for SMTP IMAP etc.
However, the mail of the added one is not being sent. Mail sent to a user on the second domain goes to that user on the first domain.
If I go into WebMail on the OurDelivery . com domain, I end up in the mailbox on OurFund.com despite the fact that the address bar of the browser says OurDelivery . com.
I’m afraid I’m completely lost.
Can you tell me what is the correct procedure for adding a second independent domain with its own IP to make mail work properly through both mailApps and WebMail
