I've been happily running Dovecot on my Mac for many years (installed via Homebrew). After upgrading to Monterey (MacOS 12.01), it no longer starts: $ sw_vers ProductName: macOS ProductVersion: 12.0.1 BuildVersion: 21A559 $ uname -a Darwin dfelicia-mac 21.1.0 Darwin Kernel Version 21.1.0: Wed Oct 13 17:33:23 PDT 2021; root:xnu-8019.41.5~1/RELEASE_X86_64 x86_64 $ sudo dovecot -F Oct 27 10:11:18 service(log): Fatal: setrlimit(RLIMIT_DATA, 268435456): Invalid argument $ mount /dev/disk1s2s1 on / (apfs, sealed, local, read-only, journaled) devfs on /dev (devfs, local, nobrowse) /dev/disk1s5 on /System/Volumes/VM (apfs, local, noexec, journaled, noatime, nobrowse) /dev/disk1s3 on /System/Volumes/Preboot (apfs, local, journaled, nobrowse) /dev/disk1s6 on /System/Volumes/Update (apfs, local, journaled, nobrowse) /dev/disk1s1 on /System/Volumes/Data (apfs, local, journaled, nobrowse) $ sudo dovecot -n # 2.3.16 (7e2e900c1a): /usr/local/etc/dovecot/dovecot.conf # Pigeonhole version 0.5.16 (09c29328) # OS: Darwin 21.1.0 x86_64 apfs # Hostname: dfelicia-mac default_internal_group = mail default_internal_user = _dovecot default_login_user = _dovenull first_valid_uid = 100 listen = 127.0.0.1 log_path = /var/log/dovecot.log mail_location = maildir:/usr/local/var/mail/%u managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date index ihave duplicate mime foreverypart extracttext 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 = login driver = pam } protocols = imap service imap-login { inet_listener imap { address = 127.0.0.1 port = 143 } inet_listener imaps { address = 127.0.0.1 ssl = no } } ssl = no userdb { driver = passwd } $ ulimit -Ha core file size (blocks, -c) unlimited data seg size (kbytes, -d) unlimited file size (blocks, -f) unlimited max locked memory (kbytes, -l) unlimited max memory size (kbytes, -m) unlimited open files (-n) unlimited pipe size (512 bytes, -p) 1 stack size (kbytes, -s) 65532 cpu time (seconds, -t) unlimited max user processes (-u) 2784 virtual memory (kbytes, -v) unlimited

Errors after freebsd upgrade
by Hanns Mattes 01 Nov '21

Hi, after upgrading Freebsd from ports dovecot is throwing the following error Oct 30 18:04:15 freebsd dovecot[59232]: doveadm(xxx(a)example.com)<84061><S3CoJf9sfWFdSAEAUmejdw>: Fatal: master: service(doveadm): child 84061 killed with signal 6 (core not dumped - https://dovecot.org/bugreport.html#coredumps - set service doveadm { drop_priv_before_exec=yes }) I (surely) may have missed something while upgrading (I've learned a lot about backup/snapshot-strategies with zfs, but to late to apply). How can I debug the erro? Regards Hanns
