Title is self-explanatory...
I have all mail clients configured for ISPconfig 2.x and now (moved to 3.x) I have to edit each account's settings (in mail client) by hand and add the @domain.net part at the end of their credentials.
LOTS OF ACCOUNTS => LOTS OF WORK
Is there any way to have ISPconfig 3.x accounts use only the username part of their email address for logging in like in 2.x
Note: I only have one domain on this server, so there is no issue with future usernames of different domains using the same account (because there won't be any other future domains hosted in this server).
PS: sorry if this has been asked before, but I didn't know how to search for it (since most terms are common in many posts).
