Nope. It didn't change anything.

Tried delivering manually while tracing the process too, and the only mention of "zlib" is this:

open("/usr/lib/dovecot/modules/lda/lib20_zlib_plugin.so", O_RDONLY) = 9 read(9, "\177ELF\2\1\1\0\0\0\0\0\0\0\0\0\3\0>\0\1\0\0\0\200\22\0\0\0\0\0\0@"..., 832) = 832 fstat(9, {st_mode=S_IFREG|0644, st_size=15080, ...}) = 0 mmap(NULL, 2110464, PROT_READ|PROT_EXEC, MAP_PRIVATE|MAP_DENYWRITE, 9, 0) = 0x7f1407f1a000 mprotect(0x7f1407f1d000, 2097152, PROT_NONE) = 0 mmap(0x7f140811d000, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED|MAP_DENYWRITE, 9, 0x3000) = 0x7f140811d000 close(9) = 0

Well, I can't see why it would hurt either. The reason we're using that directory is that the sieve plugin is compiled into lda/ by default, I think. I will try to move the sieve files into dovecot/ and remove mail_plugin_dir tomorrow, but I don't think it will help since dovecot has no problems *loading* the library.

I thinking your mail_plugin_dir is not needed, I don't have it configured, and that path doesn't even exist on my system, maybe hangover from 1.x config?

Hi! I've followed the guide at http://wiki2.dovecot.org/Plugins/Zlib to try to make Dovecot gzip incomming mails, but it doesn't seem to work. I've made pop/imap read gzipped files, and this seems to work perfectly, but LDA is still saving incomming mails in plain text. There's not too much information out there regarding the zlib module, so I'm not sure where to start debugging the problem, and was hoping someone could point me in the right direction.

The only mention of zlib when LDA is delivering a file: Sep 20 15:51:19 mail dovecot: deliver(helgemil): Module loaded: /usr/lib/dovecot/modules/lda/lib20_zlib_plugin.so The most relevant lines from dovecot.conf: mail_debug = yes protocols = imap pop3 imaps pop3s mail_location = maildir:~/Maildir mail_privileged_group = mail max_mail_processes = 1024 mail_process_size = 512

protocol imap { mail_max_userip_connections = 50 mail_plugins = fts fts_squat zlib }

protocol pop3 { pop3_uidl_format = %08Xu%08Xv mail_max_userip_connections = 50 mail_plugins = zlib }

protocol lda { postmaster_address = postmaster@monsternett.no mail_plugins = sieve zlib mail_plugin_dir = /usr/lib/dovecot/modules/lda sieve_global_dir = /etc/dovecot/sieve/ sieve_global_path = /etc/dovecot/sieve/default.sieve }

plugin { zlib_save_level = 6 zlib_save = gz fts = squat sieve = ~/dovecot.sieve sieve_dir = ~/ }

My bad, you are correct. "v2.0+" slipped by my eyes when reading your v1.x documentation at http://wiki.dovecot.org/Plugins/Zlib.

These are enough. You don't mention your Dovecot version. My guess is that your Dovecot version is too old and doesn't support saving mails with zlib.
