Hi,

I just wanted to test the zlib plugin in Dovecot 2.0 and have a problem. Delivery via LMTP works fine and the mail is saved compressed.

-rw------- 1 vmail vmail 1012 13. Jun 12:51 1276426292.M93539P15363.mail.svr02.mucip.net,S=2799,W=2850:2, # file 1276426292.M93539P15363.mail.svr02.mucip.net,S=2799,W=2850:2, 1276426292.M93539P15363.mail.svr02.mucip.net,S=2799,W=2850:2,: gzip compressed data, from Unix # zcat 1276426292.M93539P15363.mail.svr02.mucip.net,S=2799,W=2850:2, | wc 51 277 2799

But a client (both Thunderbird and Mutt) cannot access the mail.

I figured the cache might just be corrupt and I deleted all cachefiles, but the issue keeps reappearing.

Has anyone done this before?
