delivery to subfolders working??

[jpulz at frm2.tu-muenchen.de]

hi,

i'm wondering, if the "deliver directly intoo subfolder" feature of
cyrus-imapd is really working??

on my system i've installed cyrus-sasl-2.1.12 and cyrus-imapd-2.1.12
together with sendmail-8.12.8.

i have added the "FEATURE(`preserve_local_plus_detail')" to sendmail.mc.
if i send a mail maybe: user+folder at my.domain.tld the mail is accepted and
delivered, but it is shown up in the inbox and not in the subfolder.

is there something missing (a special rule in the sendmail.mc, or
something else) ???

i found no information in the net, so i ask this question here.

Thanks in advance
regards
joerg
