ok, no problem so far.

this is something I also see sometimes. You can try to add some
debug-level in roundcube (config.inc.php) and show output of the several
logfiles (ldap, sql, imap could be relevant).

have a look at mail.log how the mail flow. Are the emails to gmail are
sent immediately? Does the delay is caused from your mailserver or from
gmail (maybe graylisting).

If the mail needs that long until it's send out by postfix:
iTip-Messeages are processed by wallace (you also can have a look at
pykolab-log /var/log/kolab/pykolab.log - but set the debug level in
/etc/default/wallace to -d 8 or 9 ....)

you mean during this 30 minutes? This sounds strange. Wallace should not
interact with imap at all.

Anything in mail.log / syslog during this time?
