Unable to send mail using /usr/bin/mail

[rombert]

Hi,

I am running Zimbra 4.5.3 on OpenSUSE 10.1.

I am unable to send mails using the command-line 'mail' tool, since all emails get stuck in the /var/spool/postfix/maildrop directory.

How can I get mail to work properly?

Thank you,

Robert

Zimbra doesn't use that directory.

The directory you're looking for is /opt/zimbra/postfix....etc

Dear jholder,

Thank you for your reply. I am not trying to send mail using Zimbra's command line tools, but the ones which all the sytem uses, for example for cron jobs.

rombert:/var/spool/postfix/maildrop # which mail
/usr/bin/mail
rombert:/var/spool/postfix/maildrop # rpm -qf /usr/bin/mail
mailx-11.25-14

As you can see, the 'mail' command does not belong to the zimbra packages and does not follow the zimbra delivery rules, and that is what I am trying to fix.

Take a look here:
http://gentoo-wiki.com/Maildrop_configuration

I know you aren't using gentoo, but the config should be generally the same.
In particular, look at the postfix config section.

Because it's not a zimbra product(and the fact I've never used it), I'm not quite sure how to help you, but I think this might be your friend:

I'll simply have to look some more into that.

Thank you for your help.

Just in case someone else encounters this problem:

To make sure that the local postfix delivery works (sendmail command from existing SuSE postfix rpms), apply the following changes to /etc/postfix/main.cf:

queue_directory = /opt/zimbra/postfix/spool/
setgid_group = postdrop

This will allow the sendmail command to deliver directly to the zimbra postfix mail queue.

To be complete, please note that zimbra uses a different setgid_group that the default openSUSE one, and this causes headaches.

The default /etc/postfix/main.cf needs to be adjusted to take this into account, and also the postqueue and postdrop binaries need to be chgrp'ed to the new group.

This caused a bit of pain for me so you might want to incorporate this into the openSuSE integration procedure.

Another very easy possibility is the following:

mv /usr/sbin/sendmail /usr/sbin/sendmail.orig
ln -s /opt/zimbra/postfix/sbin/sendmail /usr/sbin/sendmail

So all sendmail requests were redirect to the Zimbra sendmail.
There is no need to fight with permissions.

FYI. If you are modifying Postfix main.cf the entries should be:

queue_directory = /opt/zimbra/data/postfix/spool
setgid_group = postdrop

And change group ownership of these files to

# chown root:postdrop /usr/sbin/postqueue
# chown root:postdrop /usr/sbin/postdrop

I've tried the above and thought it was working. However, after letting it run for a few days and checking the Zimbra logs I see these errors. Any tips guys?
