No problems, actually before posting i had some concerns about all this GNU stuff, do i do the right thing or it is too soon.
Once we decide to use this system somewhere else except internally it will be released as open source automatically.
It is just i use nsmail module for some time here and it seems to be stable and fast and IMAP Web mail under aolserver is much faster than the same PHP/Perl based imap Web mailer because ns_mail do not re-open IMAP connection every time, it keeps it in the memory(thanks multi-threading).
