how do I change the sysadmin email?

I want the admin/root (not sure about the difference) email to be [email protected]. So all problems should report there (from munin, monit, whatever).

I think the server tries to send error messages to [email protected], I get those from gmail:

Code:

Mail Delivery Subsystem [email protected]
	
9:00 AM (49 minutes ago)
		
to me
Delivery to the following recipient failed permanently:

     [B][email protected][/B]

Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the server for the recipient domain surf-anonymous.info by eforward1.registrar-servers.com. [38.101.213.200].

The error that the other server returned was:
550 unknown user

[B]Failed to create rundir (/var/run/munin): Permission denied at /usr/share/munin/munin-update line 38[/B]

So how do I change [email protected] to [email protected]?

I think I found the files I need to change, but I am afraid this has to be done from inside ispconfig, otherwise I will mess things up. I am googling and searching the manual, but I cannot find the answer to such a simple thing.

Code:

root@server1:~# grep -r -l "[email protected]" /etc/*
grep: /etc/blkid.tab: No such file or directory
grep: /etc/mail/smrsh/mail.local: No such file or directory
[B]/etc/postfix/virtual
/etc/postfix/virtual.db[/B]

Next I will worry about the actual error from munin:

Code:

Failed to create rundir (/var/run/munin): Permission denied at /usr/share/munin/munin-update line 38

 

Since I replaced postfix with msmtp (http://www.howtoforge.com/forums/showpost.php?p=309989&postcount=18), I don't know if I still have this problem.

This returned nothing:

Code:

grep -r -l "[email protected]" /etc/*

So my question now is:
Is [email protected] still part of the system? If yes, how can I redirect all emails from [email protected] to my private gmail address?
