lmtp: permission denied

Hi!

I've some permission problem which I don't quite understand:

connect to /usr/lib/postfix/lmtp[/usr/lib/postfix/lmtp]: Permission denied

# ls -l /usr/lib/postfix/lmtp
-rwxr-xr-x 1 root root 239056 Feb 4 13:15 /usr/lib/postfix/lmtp

# id postfix
uid=207(postfix) gid=207(postfix) groups=207(postfix),12(mail)

Looks quite alright, doesn't it? And actually when loggin as postfix I can manually execute lmtp.

How are you invoking this command?

Well...I don't know actually

It's postfix that's invoking it...

Meanwhile after spending some time playing and trying I get this:

Feb 4 18:17:00 server master[1853]: fatal: master_spawn: exec /usr/lib/postfix/lmtp: Permission denied
Feb 4 18:17:01 server postfix/master[29605]: warning: process /usr/lib/postfix/lmtp pid 1853 exit status 1

Ok. So you have defined a transport in Postfix to use it.

Can you post the bottom bits of /etc/postfix/master.cf. Feel free to lose all the comments.

okay. Using Cyrus to deliver (which I don't..) I'd expect to see mailbox_transport = cyrus and comment out mailbox_command.

It 'knows' how to call cyrus as it's defined in your master.cf.

That's my 2p.

Hmm. Well, at least no errors show up in the log no more. But no mail as well...and I couldn't find any file in /var/spool/postfix/defer[red]. Seemed like the argv in master.cf is wrong when emerging postfix:

Feb 4 19:13:25 server pipe[5774]: fatal: pipe_comand: execvp /cyrus/bin/deliver: No such file or directory
Feb 4 19:13:25 server postfix/smtpd[5767]: disconnect from localhost[127.0.0.1]
Feb 4 19:13:26 server postfix/pipe[5773]: 96D2EFB843: to=<tcn@localhost.server.localdomain>, orig_to=<tcn@localhost>, r
elay=cyrus, delay=1, status=bounced (Command died with status 1: "/cyrus/bin/deliver")

So, I fixed it - and got:

Feb 4 19:15:51 server postfix/pipe[5917]: 77FC8FB8E9: to=<tcn@localhost.server.localdomain>, orig_to=<tcn@localhost>, r
elay=cyrus, delay=0, status=deferred (temporary failure. Command output: couldn't connect to lmtpd: Connection refused_
421 4.3.0 deliver: couldn't connect to lmtpd_ )

Hm, some auth related? I didn't configure anything regarding auth and lmtp which I probably should have

magic919 · Post by **magic919** » Sat Feb 04, 2006 6:28 pm

There's not usually any auth with lmtp. Did you change the master.cf to /usr/lib/cyrus/deliver then? Not sure exactly what you've changed.

someone12345 · Post by **someone12345** » Sat Feb 04, 2006 6:30 pm

yes, /usr/lib/cyrus/deliver

someone12345 · Post by **someone12345** » Sat Feb 04, 2006 7:33 pm

No idea?

magic919 · Post by **magic919** » Sat Feb 04, 2006 7:36 pm

I'm not understanding why you still have lmtp errors. There's no lmtp meant to be going on with Postfix now. Doesn't add up. You did reload Postfix after taking it out??

someone12345 · Post by **someone12345** » Sat Feb 04, 2006 7:46 pm

yes, sure

magic919 · Post by **magic919** » Sat Feb 04, 2006 7:47 pm

Hmm. I'm lost. Wanna stick up the current confs, as you did above. The truth must be out there

someone12345 · Post by **someone12345** » Sun Feb 05, 2006 10:07 am

It works!

Dunno what went wrong yesterday...

But I'm wondering where the "localhost" does come from:

to=<tcn@localhost.server.localdomain>, orig_to=<tcn@localhost>,
relay=cyrus, delay=0, status=sent (server.localdomain)

I configured postfix myhostname = server.localdomain.

magic919 · Post by **magic919** » Sun Feb 05, 2006 12:38 pm

The localhost is part of the default for mydestination parameter in Postfix. A quick postconf mydestination will show this.
