service(imap-login): Fatal: setrlimit(RLIMIT_DATA, 268435456): Invalid argument macOS

I fixed the issue with Dovecot not starting on macOS Ventura by adding this to 10-master.conf: service log { vsz_limit = 0 } But now when I try to login via Imap on port 143 I get the same error for imap-login: Feb 20 15:55:41 imap-login: Error: Feb 20 15:55:41 service(imap-login): Fatal: setrlimit(RLIMIT_DATA, 268435456): Invalid argument Feb 20 15:55:41 imap-login: Fatal: master: service(imap-login): child 11781 returned error 89 (Fatal failure) Feb 20 15:55:41 master: Error: service(… [View More]imap-login): command startup failed, throttling for 60.000 secs Feb 20 16:13:04 imap-login: Error: Feb 20 16:13:04 service(imap-login): Fatal: setrlimit(RLIMIT_DATA, 268435456): Invalid argument Feb 20 16:13:04 imap-login: Fatal: master: service(imap-login): child 20370 returned error 89 (Fatal failure) Feb 20 16:13:04 master: Error: service(imap-login): command startup failed, throttling for 60.000 secs Config: sudo /usr/local/sbin/dovecot -n # 2.3.20 (80a5ac675d): /usr/local/etc/dovecot/dovecot.conf # OS: Darwin 22.3.0 arm64 apfs # Hostname: mail-server-mac-studio.local auth_mechanisms = plain login auth_verbose = yes auth_verbose_passwords = yes default_internal_group = mail default_internal_user = _dovecot default_login_user = _dovenull first_valid_gid = 0 first_valid_uid = 102 last_valid_gid = 501 last_valid_uid = 105 log_path = /var/log/dovecot.log mail_gid = 102 mail_location = maildir:/usr/local/virtual/%d/%u mail_uid = 102 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 = /usr/local/etc/dovecot/dovecot-sql.conf.ext driver = sql } protocols = imap pop3 service auth { unix_listener /var/spool/postfix/private/auth { group = _postfix mode = 0660 user = _postfix } unix_listener auth-userdb { mode = 0660 user = _vmail } } service imap-login { vsz_limit = 0 } service log { vsz_limit = 0 } ssl_cert = </etc/letsencrypt/live/mail.bordo.com.au/fullchain.pem ssl_dh = # hidden, use -P to show it ssl_key = # hidden, use -P to show it userdb { driver = prefetch } userdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol imap { mail_max_userip_connections = 40 } Quitting Dovecot and restarting and I now get: Feb 20 17:01:11 master: Info: Dovecot v2.3.20 (80a5ac675d) starting up for imap, pop3 (core dumps disabled) Feb 20 17:01:11 master: Error: service(anvil): command startup failed, throttling for 2.000 secs Then trying to connect on port 143 log says: Feb 20 17:20:08 master: Error: service(config): command startup failed, throttling for 2.000 secs Feb 20 17:20:08 config: Error: Feb 20 17:20:08 service(config): Fatal: setrlimit(RLIMIT_DATA, 268435456): Invalid argument Feb 20 17:20:08 anvil: Fatal: master: service(anvil): child 43250 returned error 89 (Fatal failure) Feb 20 17:20:08 config: Fatal: master: service(config): child 52530 returned error 89 (Fatal failure) Feb 20 17:20:08 stats: Fatal: master: service(stats): child 52531 returned error 89 (Fatal failure) Feb 20 17:20:08 stats: Error: Feb 20 17:20:08 service(stats): Fatal: setrlimit(RLIMIT_DATA, 268435456): Invalid argument Feb 20 17:20:08 master: Error: service(stats): command startup failed, throttling for 2.000 secs Feb 20 17:20:10 config: Error: Feb 20 17:20:10 service(config): Fatal: setrlimit(RLIMIT_DATA, 268435456): Invalid argument Feb 20 17:20:10 config: Fatal: master: service(config): child 52532 returned error 89 (Fatal failure) Feb 20 17:20:10 master: Error: service(config): command startup failed, throttling for 4.000 secs Feb 20 17:20:10 imap-login: Fatal: Error reading configuration: read(/usr/local/var/run/dovecot/config) failed: EOF - Also failed to read config by executing doveconf: /usr/local/var/run/dovecot/config is a UNIX socket (path is from CONFIG_FILE environment) Feb 20 17:20:10 master: Error: service(imap-login): command startup failed, throttling for 2.000 secs Any suggestions?

Get correct subjects in summary but wrong article body after transitioning between servers
by Steinar Bang 19 Feb '23

19 Feb '23

I am transitioning between servers (both debian 11.6 with dovecot 2.3.13) and I'm seeing some strange behaviour after the transition: it seems like dovecot is listing the correct subject for the test messages I'm sending in what's shown in my MUA's summary. But the body of the message is an old message. Dovecot is serving messages from Maildir folders in the users' home directories. And I may have messed up some things here: I rsynced the maildirs and then still got some deliveries both … [View More]

Roundcube <-> Dovecot timeouts under very moderate load on big Dovecot nodes
by Malte Schmidt 18 Feb '23

18 Feb '23

Due to a recent topic regarding the performance of the Roundcube webmailer with Dovecot as a backend, I set up imapproxy successfully, shrinking the response latency of the webmailer heavily, which is great. However, I still encounter strange timeouts on some requests when Roundcube tries to access Dovecot. Be it for authentication or to FETCH data. I run the tests/benchmarks via distributed JMeter from 4 nodes, they access the webmailer which in turn accesses the Dovecot via imapproxy. There … [View More]

dovecot_login accepts blank password for exim smtp auth
by Jeff Rogers 18 Feb '23

18 Feb '23

Hi all, I recently discovered a configuration issue on my system where a system user account had a blank rather than invalid or disabled password in the passwd/shadow database. The user could not be logged into through login/telnet/ssh because it was marked as a system account (uid < 100). Dovecot also would not authenticate the user for the same reason. However, I'm using exim using dovecot_login for authentication, and that would authenticate the user with a … [View More]

Special authentication use case
by Philippe MARASSE 17 Feb '23

17 Feb '23

Folks, I'm trying to configure dovecot SASL with two use cases : - First with XOAUTH2 : I've managed to get it working, pretty right out of the box, developers have done a great job :-) - Second with Client TLS Certificate with no luck. Let me explain, the certificate brought by the client does not have any clue of associated email, I have to check that username (=email) sent by the client is really related to some information included in the certificate (I have to extract … [View More]

Re: SOLVED: Re: Dovecot does not start on MacOS 12.01, and now 13.2.1 - RLIMIT_DATA

Sorry, replying to an old thread found on mail-archive.com <http://mail-archive.com/>, so it’s not threaded email. https://www.mail-archive.com/dovecot@dovecot.org/msg84776.html I have just installed Dovecot onto Mac Studio running Ventura (macOS 13.2.1) and get the same error with Dovecot 2.3.20: service(log): Fatal: setrlimit(RLIMIT_DATA, 268435456): Invalid argument Adding the ’service log’ stanza to 10-master.conf fixed the issue. Is this still the correct way to handle it? If … [View More]

Could not override "mail_location" with "userdb_mail" statment in "/etc/passwd"
by Xavier 17 Feb '23

17 Feb '23

Hi, ** Using Dovecot 2.2.22 and Postfix 3.1.0 ** I plan to migrate all accounts on my server from mbox to maildir storage but before i want to make some tests on dedicated accounts. To do so i want to overide the general "mail_location" ( mail_location = mbox:~/mail:INBOX=/var/mail/%u ) with "maildir:~/Maildir" only for some test accounts. To do so i modified my "/etc/passwd" file using something like that : testm2m_mydomain.tld:x:2122:2122::/home/mail/testm2m_mydomain.tld:/bin/false:… [View More]

Corrupted sizes in cache once again
by Tim Evers 15 Feb '23

15 Feb '23

Hi, I run a fairly large Dovecot Installation (around 100k mailboxes) on several servers. gzip compression is on. Every once in a while I get the dreaded "cache corruption" messages in the log: Error: Corrupted record in index cache file /[redacted]/Maildir/dovecot.index.cache: UID 3868: Broken physical size in mailbox INBOX: read(zlib(/[redacted]/Maildir/cur/1674129792.M797543P21755.node2,S=8099,W=8276:2,)) failed: Cached message size smaller than expected (2877 < 8099, box=INBOX,… [View More]
