Hi, we run Dovecot 2.2.13 on Debian Wheezy with a couple thousand mailboxes. We have two users that repeatedly trigger an OOM condition with IMAP.

I've been using dovecot for years, been working great. However recently I've come across two issues. The first issue unfortunately I have little information on, mail_debug hasn't provided anything useful either (in fact it looks like the login request that fails doesn't even get logged at all).

This is in follow-up to https://dovecot.org/pipermail/dovecot/2017-December/110443.html I had mail_plugins = "zlib", but zlib_save wasn't set (my mailboxes were not compressed). It seems that when the zlib plugin is enabled, but zlib_save isn't set, the zlib plugin aborts on a regular basis---on a single-user system, I was seeing it about 150 times a day. Panic: file
