mail error messages

I saw these error messages in the mail.log:

Code:

They are sent every 5 minutes, so it could be munin is trying to send messages.

This is AFTER I replaced postfix with msmtp.

Searching for "127.0.0.2" returned this:

Code:

$ grep -r -l "127.0.0.2" /etc/*
grep: /etc/blkid.tab: No such file or directory
/etc/network/interfaces

Just in case it helps, here is the syslog:

I agree. This is why I made a text search for "127.0.0.2" (and found nothing).

Code:

$ grep -r -l "127.0.0.2" /etc/*
grep: /etc/blkid.tab: No such file or directory
/etc/network/interfaces

Any idea where this could be located?

 

I must be blind. It is in /etc/network/interfaces:

Code:

# Auto generated venet0 interface
auto venet0
iface venet0 inet manual
	up ifconfig venet0 up
	up ifconfig venet0 [B]127.0.0.2[/B]
	up route add default dev venet0
	down route del default dev venet0
	down ifconfig venet0 down

Is this something that ispconfig does?

 

This is the etc/hosts file:

Code:

127.0.0.1 localhost.localdomain localhost
# Auto-generated hostname. Please do not remove this comment.
192.210.214.129 server1.surf-anonymous.info  server1
::1 localhost.localdomain localhost

Where do I add the 127.0.0.2 ?

I think this file is also auto generated.

I am googling all morning on this issue.

You are more experienced. If you could tell me what is the meaning of this "secondary internal" IP address 127.0.0.2 (compared to 127.0.0.1), please tell me. Is it because of the second domain? What does this do?

 

I tried this and it worked. Thanks!

Code:

[B]127.0.0.2 server1[/B]
127.0.0.1 localhost.localdomain localhost
# Auto-generated hostname. Please do not remove this comment.
192.210.214.129 server1.surf-anonymous.info  server1
::1 localhost.localdomain localhost
