Hi,

I've observed that dovecot doesn't displays all mails from compressed via gzip mailbox (mbox). At the same time "mutt -f mailbox.gz" displays it correctly with all messages.

I'm using archivemail to archive old mails. Internally it creates new "gzip" archive with "expired" messages and then concatenates it with archive.

The easiest way to reproduce it without archivemail is to create two mailboxes, gzip them independently and then concatenate to one gzip archive. mutt, gunzip and other tools understands such archives.

Also I've shared such mbox: http://dion.org.ua/uploads/2011/07/dovecot_test_gzip.gz

It should contains ~20 messages. dovecot will "see" only two first.

PS. % sudo dovecot --version 2.0.13
