cannot set email alias with dot (".") in the name

[radim_h]

Hello guys,

i'm using Debian Etch 2.6.18-4-686 and ISPConfig Version: 2.2.14
User Prefix is [DOMAIN]_
Ispconfig works well, but couple months after server came into production, i discovered this problem..

Domain administrator can add user with email in format
"some.name" and any mail alias in format "somename" without problem

But when user email is "somename" and mail alias "some.name" is added,
this alias is not displayed (ISP user>advanced settings), it also doesn't appear in /etc/postfix/virtusertable,
but it is included in ispconfigdb tab isp_isp_user
and it stays in database also when user is deleted

had anyone same problem, ot idea what to do with this problem ?
