Re: LDA ignores virtual mailbox settings

Hi,

Toni Mueller, 27.12.20:

16:04:16 dovecot: lda(user@example.com)<5291>: Error: Mailbox INBOX: Failed to autocreate mailbox: Mailbox INBOX: open(/var/mail/user@example.com) failed: Permission denied (euid=12345(mailbox) egid=12345(mailbox) missing +w perm: /var/mail, we're not in group 8(mail), dir owned by 0:8 mode=0775) 16:04:16 dovecot: lda(user@example.com)<5291>: msgid=20201226224933.014608@laptop.example.com: save failed to open mailbox INBOX: Mailbox INBOX: Failed to autocreate mailbox: Mailbox INBOX: open(/var/mail/user@example.com) failed: Permission denied (euid=12345(mailbox) egid=12345(mailbox) missing +w perm: /var/mail, we're not in group 8(mail), dir owned by 0:8 mode=0775) 16:04:16 postfix/pipe[5284]: 8CD6CE072E: to=user@example.com, orig_to=userA@example2.com, relay=dovecot, delay=62083, delays=62083/0.04/0/0.04, dsn=4.3.0, status=deferred (temporary failure)

In /etc/postfix/master.cf, I have this to call it:

dovecot unix - n n - - pipe flags=DRhu user=_mailbox argv=/usr/lib/dovecot/deliver -f ${sender} -d ${user}@${domain} -a ${recipient}

I've tried strace-ing dovecot-lda, but it didn't really help me to understand why it discards the result of the userdb lookup.

Can anyone please provide a cluebat, please?

I'd change the setup towards postfix handing over the messages to dovecot via lmtp.

You can easily achive this by setting relay_domains = btree:/etc/postfix/relay-transport in your postfix configuration and creating a file /etc/postfix/relay-transport: your_mail_domain lmtp:unix:private/lmtp-dovecot
