In Virtualmin, there is no method to make username's prefix delimita including '@' like 'firstname.lastname@example.org'. In Webmin, it is passible.
Is this reason for technic? I do want make it !!!
"In Virtualmin, there is no method to make username's prefix delimita including '@' like 'email@example.com'."
Actually, that's not true. Username format is wholly configurable, and @ in the username is possible. There are some caveats, though.
There's a FAQ about this particular question here:
Thank you for reply !
and sorry of my too late reply.
I could make user like ' firstname.lastname@example.org' with your suggestion.
Then I tested my Mail Server.
I realized one problem.
When using POP, the 'email@example.com' was possible,
bat when using SMTP, I must use the 'user-example.com' with smtp-Auth.
Can I use same user-name with both Auth, POP and SMTP ?.
Thank you !
Please re-read the FAQ I linked you to. It covers this issue and the configuration change you need to make to the saslauthd configuration.
The same user-name meen 'firstname.lastname@example.org'.
I was able to resolve above problem.
This Server is the BackUp Server, and It had to be a same username with the Main Server in rental Space.
Thank you so much !!
I could grant my boss's request.
