I need to host on one box some virtual servers using regular user.domain user names for email, and some virtual servers using user@domain (these are ones migrated from Plesk).
In testing this, accessing POP or IMAP is not a problem - I can have a server template with the appropriate format for the user name in the “mail for domain” section.
However for SMTP authentication it seems I need to alter saslauthd with the -r flag (http://www.virtualmin.com/documentation/email/pop-and-imap).
My question is this: If I do this, will both SMTP login formats be supported?
Ie Will virtual server A setup with a template for user.domain be able to do SMTP authentication, and will virtual server B with a template for user@domain be able to do SMTP authentication?
