dovecot ssl error message from my own connections
by Esteban L 01 Apr '19

01 Apr '19

Hello all, Just a minor thing. Not a big deal, because everything works fine, and I feel secure with my setup. But, I get this error message pretty much throughout the day/night, which appears to come from my own mail clients (desktop or mobile). I would like to resolve it, because it must me something (that is not good--that I may not understand), that may have other ramifications. So, here it is. date time myserver dovecot: imap-login: Debug: SSL error: SSL_read() syscall failed: Connection reset by peer Anyone have a suggestion of what this might hint to, other than obvious SSL. I tried parsing through various logs, but the most I find is just this single line. I can produce it, whenever I close my email client. Thanks in advance.

Possible bug with last_login plugin and PostgreSQL
by Zhang Huangbin 01 Apr '19

01 Apr '19

Dear all, I'm trying to get last_login plugin working with PostgreSQL, but seems Dovecot doesn't handle duplicate key while updating last login time (note: same setting works fine with MariaDB). I wonder whether it's a bug of Dovecot or i should handle this with PostgreSQL trigger.

Hi. I have a question. Can I limit the maximum number of messages I can sync per mailbox? Even if there are 10000 messages, I want to sync with the specified number of times. Ex)max sync mail count = 5000 (or 1000 or 2000..Outlook view message 5000) Thank you.

by luckydog xf 31 Mar '19

31 Mar '19

hello, I'm successfully send and receive emails by postfix and dovecot, but folder name 'Sent' is gone, all sent emails are located in Drafts folder. Anything wrong? Guess it has something to do with mailbox and location. Here is `doveconf -n` ------------------ auth_cache_size = 1 M auth_debug_passwords = yes auth_mechanisms = plain login auth_ssl_username_from_cert = yes auth_verbose = yes auth_verbose_passwords = yes import_environment = TZ login_trusted_networks = 172.16.0.0/12 mail_location = maildir:/var/mail/%n/Maildir mail_privileged_group = mail namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocols = imap lmtp service auth-worker { user = $default_internal_user } service auth { unix_listener /var/spool/postfix/private/auth { mode = 0666 } } service imap-login { inet_listener imap { port = 0 } inet_listener imaps { port = 993 ssl = yes } } service lmtp { unix_listener lmtp { mode = 0666 } } service pop3-login { inet_listener pop3 { port = 110 } } ssl = required ssl_cert = </etc/ssl/certs/dovecot.pem ssl_dh = # hidden, use -P to show it ssl_key = # hidden, use -P to show it userdb { driver = prefetch } userdb { args = uid=mail gid=mail home=/var/mail/%u driver = static } verbose_proctitle = yes ----- I also checked mail dir, it has /var/mail/XXX/Maildir/.send/ So anything wrong?

Hi, if i use 'doveadm rebuild attachments' command with maildir mailboxes, will anything happen to files with emails? For example, will file name change? Or better, will anything, which could trigger data backup, happen to files containing emails? Thanks. azur

Purges now happen 5 times faster
by Steve Litt 29 Mar '19

29 Mar '19

Hi all, I use Claws-Mail to look inside my local (same metal) Dovecot server. All incoming mail is dumped into Dovecot folders via procmail. All of a sudden today, mass purges of "marked for delete" happen about 5 times faster. The process used to be a significant productivity destroyer, but now is easy to work with. In other words, it's a good thing, but until I know why this happened, I'll have that little voice inside telling me there's some evil side effect somewhere. Does anybody know any reason this should have happened? I'm using Dovecot 2.3.5 (513208660) and Claws-Mail 3.17.3. Thanks, SteveT

Hi, I've been having an issue with the indexer giving me errors on mailbox in dovecot. I managed to narrow it down to a specific email in that mailbox. Various dovecot functions have issues with this email. The email itself is just spam. I can email it to you if you want to analyse it. I did run it through mbox-anonymize but its not clear to me that that would be of any use. Happy to email the suspect email privately to anyone who wants it. /home is mounted nfs4 and is zfs on the nfs server.
