account creation in cyrus

[JOYDEEP]

dear list,

I have a running egroupware with auto cyrus imap creation facility.
If I set     Mail server login type---->Standard (login name identical
to eGw domain name)

the account created under cyrus is like ( example for account aftab)
user/aftab
user/aftab/Sent
user/aftab/trash

But after sending mails from the felamimail; no mails reached to the
destination.

If  I set     Mail server login type----> Virtual mail manager

the account created under cyrus is like ( example for account aftab)
user/aftab at kolkatainfoservices.in

and now mail from felamimail reaches to the destination ( other account)
But here the creation of sent and trash folder is missing. Could any one
suggest me a fix so that I
can use #1  or #2 with the creation of sent and trash folders ?
