[Dovecot] pop3 migration
Hi, I have problems with pop3 migration, the server disconect the dovesync when fetching mails after 5 minutes with this error in server log:
xx.xx.xx.xx [28F4] 11:54:05 <<< RETR 6548 xx.xx.xx.xx [28F4] 11:54:05 >>> +OK 47522 octets xx.xx.xx.xx [28F4] 11:54:05 <<< RETR 6549 xx.xx.xx.xx [28F4] 11:54:05 >>> +OK 355289 octets xx.xx.xx.xx [28F4] 11:54:05 <<< RETR 6550 xx.xx.xx.xx [28F4] 11:54:05 >>> +OK 9638 octets xx.xx.xx.xx [28F4] 11:54:05 <<< RETR 6551 xx.xx.xx.xx [28F4] 11:54:05 >>> +OK 2188 octets xx.xx.xx.xx [28F4] 11:59:05 >>> -ERR Command unrecognized: "" xx.xx.xx.xx [28F4] 11:59:05 *** <info@istan.cz> 6551 477693894 00:12:55 ERROR xx.xx.xx.xx [28F4] 11:59:05 Disconnected
and this in dovecot log:
dsync(info@istan.cz): Debug: imapc(mail.stable.cz:143): Authenticated successfully dsync(info@istan.cz): Debug: pop3c(mail.stable.cz): Looking up IP address dsync(info@istan.cz): Debug: pop3c(mail.stable.cz): Connecting to 88.86.120.212:110 dsync(info@istan.cz): Debug: pop3c(mail.stable.cz): Authenticating as info@istan.cz dsync(info@istan.cz): Error: pop3c(mail.stable.cz): Server disconnected unexpectedly dsync(info@istan.cz): Error: pop3_migration: Failed to get header for msg 1: Disconnected dsync(info@istan.cz): Error: pop3_migration: Failed to get header for msg 2: Disconnected dsync(info@istan.cz): Error: pop3_migration: Failed to get header for msg 3: Disconnected dsync(info@istan.cz): Error: pop3_migration: Failed to get header for msg 4: Disconnected
is there any timeout in dovecot for 300s? can anybody point me where may be some problem? This error occurs everytime i test it and the mail box has cca 2GB, on small mailboxes is no problem, i try this patch: http://hg.dovecot.org/dovecot-2.1/rev/ab6a4455b27d on dovecot version 2.1.7 but the problem isn't solved.
Thanks for help Tomas Herceg

Looks like a bug. But in Dovecot POP3 client or the POP3 server? Apparently either Dovecot sends an empty line after RETR or the server thinks Dovecot sends it. Can you get the actual TCP traffic logs? and/or set pop3c_rawlog_dir and see if it's there.
Probably on server side ... the problem was only on big mailboxes which is used by IMAP, so there is no problem and we have already migrated all to dovecot. ;) Thanks for your reply.
