[fetchmail-users] fetchmail with dovecot as mda

[Jerry <je...@se...>]

I was asked to see if it was possible to get fetchmail to deliver mail
directly to a dovecot server. It is presently working with a Postfix
MTA. The system is comprised of solely virtual users.

From the Postfix "master.cf" file:

dovecot   unix  -       n       n       -       -       pipe
  flags=DRhu user=vmail:vmail argv=/usr/local/libexec/dovecot/deliver
  -f ${sender} -d ${user}@${nexthop} -a ${recipient}

I have tried different ways of configuring the "mda" settings in
fetchmail; however, none of them work. This example stated that it
couldn't open the dovecot log file and that it exited with an error 75.

user 'user@isp' there with password 'secret' is 'user' here options
  forcecr dropdelivered smtpaddress 'isp.com' ssl sslcertpath
  '/usr/local/etc/postfix/certs/' sslfingerprint
  '74:8F:40:34:7F:B4:5E:23:99:B3:A9:92:93:67:13:8A' mda
  "/usr/local/libexec/dovecot/deliver -f %F -a %T"

I am not even sure if it is possible. I cannot find any real
documentation via Google from anyone who has actually gotten it to
work. This is being run on a FreeBSD machine.

A quick Google search suggests that the problem is usually that you're
not running fetchmail and dovecot as the same user. Doing that, or
delivering via SMTP, seems to solve it in the cases I found.

I noticed that also. Dovecot runs as user:group "vmail:vmail". How do I
get fetchmail to deliver mail using "vmail" as the user ID?

You don't* - you run fetchmail as the user "vmail".

How you do that depends on how you're running fetchmail. If it's on
boot as a daemon you'll need to change the startup script, or the
config file it calls. If it's from cron simply remove it from the
current crontab and add it to vmail's crontab instead.


*Well, you could probably use sudo to achieve this, but it's likely to
be significantly more complicated to get working.
