[Dovecot] IMAP COMPRESS not announced while using imap_zlib plugin
I'm trying to enable the IMAP COMPRESS plugin listed here: http://wiki2.dovecot.org/Plugins/Compress
I have added zlib globally and imap_zlib to the imap protocol.
This is the output from doveconf -n with regards to mail_plugins: --cut-- mail_plugins = zlib protocol imap { mail_plugins = zlib imap_zlib } --cut
But it seem like the feature is not announced when connecting to the IMAP server:
- OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE STARTTLS LOGINDISABLED AUTH=DIGEST-MD5 AUTH=CRAM-MD5] Dovecot ready.
I would expect something like COMPRESS=DEFLATE.
I haven't enabled any compression for the Maildir files, zlib_save_level and zlib_save is not set. Does IMAP COMPRESS only work if the mailbox is compressed?
Best regards Henrik Larsson

Log in first.

Not yet.

Thank you Timo, I see it is listed after login.
The reason why I didn't check this was the explanation in the RFC. Here the feature is announced before logging in: --cut-- The following example illustrates how commands and responses are compressed during a simple login sequence:
S: * OK [CAPABILITY IMAP4REV1 STARTTLS COMPRESS=DEFLATE]
C: a starttls
S: a OK TLS active--cut--
Is there any way I can see in the logs if IMAP COMPRESS is used?
