Topic: Domain alias with some users migrated to iRedMail
I have domain alias + shadowAddress setup on iRedMail so together with mails going to old mail server and being forwarded to the iRedMail to be delivered to the new mail server.
* old mail server - domain mail.mydomain.com with user firstname.lastname@example.org -> this user has alias setup to send any mails to email@example.com
* new mail server (iRedMail) - domain mail.mydomain.com with user firstname.lastname@example.org and shadowAddress of email@example.com
MX record for mydomain still pointing to old server
MX record for mydomain2 pointing to iRedMail server
What i have noticed is when myuser sends email out to any other user to the mydomain.com on iRedMail, they get 'no virtual mailbox' error since i assume it knows because iRedMail has the mydomain.com domain, it is not consulting the mx record but sending it internally. (correct me if i am wrong)
But what i would like to do is iRedMail to still send mails to mydomain.com to the old mailserver while i migrate the mail box/MX record etc
can this be done?
thanks in advance
