dovecot --version 2.3.20 (80a5ac675d) having the following setup: (1) aioria:/srv/franper/mail # cat /etc/dovecot/users ***snip*** ventas-respaldo@franper.net:*snip*:1001:1000::/srv/franper/mail/ventas (2) aioria:/srv/franper/mail # ls -lha total 0 drwxr-x---. 1 1001 1000 238 Mar 13 05:07 . drwxr-sr-x. 1 1000 1001 62 Oct 24 21:29 .. ***snip*** drwxr-x---. 1 1001 1000 578 Mar 4 18:53 ventas drwx------. 1 1001 1000 246 Mar 13 05:07 ventas-respaldo (3) aioria:/srv/franper/mail # date -u Mon Mar 13 05:09:06 UTC 2023 where (1) I'm trying to expose the contents of the mbox ventas as ventas-respaldo@franper.net, well, for some reason it disregards that I'm pointing at /srv/franper/mail/ventas BUT does take the directory path at /srv/franper/mail and then constructs a /srv/franper/mail/ventas-respaldo path, which you can confirm with (2) showing ventas-respaldo modification date being today's date (3) because a client (Thunderbird 103 if you're interested but I think that it's not its fault at all) tried accessing ventas-respaldo@franper.net which should have pointed to /srv/franper/mail/ventas but instead did this very weird thing. Nowhere in /etc/dovecot/users do I have a line pointing to /srv/franper/mail/ventas-respaldo. dovecut just generates it somehow. dovecot -n: # 2.3.20 (80a5ac675d): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.20 (149edcf2) # OS: Linux 6.2.1-1-default x86_64 ## (OpenSUSE micro OS) # Hostname: aioria disable_plaintext_auth = no mail_location = maildir:/srv/franper/mail/%n managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables b ody 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 = scheme=CRYPT username_format=%u /etc/dovecot/users driver = passwd-file } plugin { sieve = file:~/sieve;active=~/.dovecot.sieve } ssl = required ssl_cert = <*snip* ssl_cipher_list = ALL:!DH:!kRSA:!SRP:!kDHd:!DSS:!aNULL:!eNULL:!EXPORT:!DES:!3DES:!MD5:!PSK:!RC4:!ADH:!LOW@STRENGTH ssl_key = # hidden, use -P to show it ssl_options = no_compression ssl_prefer_server_ciphers = yes userdb { args = username_format=%u /etc/dovecot/users driver = passwd-file } tell me if you need the sysreport tar and big thanks
