So, i have set up iredmail in iredadmin with 2 virtual domains, one is domain.com and another is domain.net
The domain.net is used for testing / development purposed so since the mail server launched, we stopped using it anymore, hence it was disabled in iredadmin.
And now we're facing problem that we just knew:
Everytime we wanted to send email from domain.com to domain.net i always received mailer daemon which is
"Undelivered Mail Returned to Sender"
Mail for domain.net loops back to myself
What to do? Here's my postfix main.cf file:
myhostname = domain.com
myorigin = domain.com
mydestination = localhost, localhost.localdomain, domain.com
mydomain = domain.com
virtual_alias_domains =
Any advice about how to fix this error? Thanks in advance
Postfix doesn't know that it is also responsible for the .net address. Just add it to mydestination and everything should be fine.
mydestination = localhost, localhost.localdomain, domain.com, domain.net
Alternatively, if all mail to domain.net was to go to a single user, one would use virtual aliases:
virtual_alias_domains = domain.net
virtual_alias_maps = static:root
This would redirect all mail to domain.net to your root user. No change to mydestination is neccessary in that case.
