dsync having problems with @-sign in mailbox names
by Philip Iezzi 28 Sep '19

28 Sep '19

Hi there We are running Cyrus-to-Dovecot migrations using dsync on destination Dovecot server (Debian Stretch / latest Dovecot 2.3.7.2 from community repo) like this: $ doveadm -o mail_fsync=never backup -R -u <username> imapc: For imapc configuration to connect to remote Cyrus server, see below [1]. While this works great for hundreds of mailaccounts, dsync fails with the following error on accounts with @-sign in mailbox names: dsync(<username>): Error: Failed to access mailbox INBOX/entrance/admin@example: Invalid mailbox name I can confirm, Dovecot supports @-sign in mailbox names and no client (tested with Thunderbird, Apple Mail, Roundcube webmail) has issue with this character. Also Cyrus was always supporting this. So I guess this is an issue with dsync. Can we somehow tune charset (UTF-8 ?) in imapc configuration? Thanks, Philip [1] /etc/dovecot/conf.d/90-migration.conf: ## IMAP imapc_host = imap.example.com imapc_port = 993 imapc_ssl = imaps imapc_ssl_verify = yes imapc_user = %u imapc_master_user = cyrus imapc_password = ********** imapc_features = rfc822.size fetch-headers mail_prefetch_count = 20 imapc_list_prefix = INBOX ## POP3 pop3c_host = pop3.example.com pop3c_port = 995 pop3c_ssl = pop3s pop3c_ssl_verify = yes pop3c_user = %u pop3c_master_user = cyrus pop3c_password = ********** namespace { prefix = POP3-MIGRATION-NS/ location = pop3c: list = no hidden = yes } protocol doveadm { mail_plugins = $mail_plugins pop3_migration } plugin { pop3_migration_mailbox = POP3-MIGRATION-NS/INBOX }

Mail received but not indexed?
by Marc Roos 28 Sep '19

28 Sep '19

I have recently that some users are complaining about that they are not getting emails. While I see that they are delivered and in the inbox. When I do a doveadm force-resync -u xxxx INBOX it resolves the problem. I think this is something recent. Where/how should I resolve this issue? Recent changes 1. did some os updates 2019-08-27 2. provider took away the ssd for index storage (maybe config issue having less iops storage?) CentOS Linux release 7.6.1810 (Core) dovecot-2.2.36-3.el7.x86_64 mail_location = mbox:~/mail:INBOX=/var/spool/mail/%u:CONTROL=~/mail/control:INDEX=/var/d ovecot2/%u/index:LAYOUT=maildir++ PS during force-resync, I am getting these "index/.INBOX/dovecot.index.log was locked for 176 seconds" on some users

limits in high-security mode with ssl
by sergio 27 Sep '19

27 Sep '19

Hello. I'm using dovecot in high-security mode: service_count = 1 for imap-login service starttls is requires, so the maximum number of active connections is process_limit (which is set to 1024) for the same imap-login service. But with this setup I got: doveconf: Warning: service auth { client_limit=1000 } is lower than required under max. load (1324) doveconf: Warning: service anvil { client_limit=1000 } is lower than required under max. load (1227) 1. Where did 1324 and 1227 come from? 2. How configuration should be updated so these warnings disappear? -- sergio.

Its not down, its most likely your providers DNS resolution. www.dovecot.org resolves to: ipv4 : 94.237.85.39 ipv6: 2a04:3542:1000:910:acc1:5bff:fe5e:3b83 Best Regards, D.

I am not able to reach the dovecot site on any one of three connections (home, office, mobile). Trying to look up DNS shows no records. -- But just because you've seen me on your TV Doesn't mean I'm any more enlightened than you

File manager or browser for IMAP?
by Steve Litt 26 Sep '19

26 Sep '19

Hi all, I could really use a file manager or browser to browse my Dovecot IMAP. Ideally it would have hotkeys to move, copy, delete and send. The send part needn't be coded: Just a call to a shellscript which can handle the send the way it's locally the most convenient. Anyone know of such a file manager or browser for IMAP?

Typo in wiki
by Mika Pflüger 26 Sep '19

Hi, on https://wiki2.dovecot.org/Plugins/LastLogin the link to the new documentation page is wrong and leads to a 404. The correct link is https://doc.dovecot.org/plugin-settings/last-login-plugin/ . I tried correcting it myself in the wiki, but the Captcha was too hard for me. Cheers, Mika
