Topic: What this error means ? network_biopair_interop error reading 5 bytes

iRedMail version: 0.9.4
Linux Distro: Centos 6.7
Accounts backend: MySQL


Hi all,

today I did a "cat /var/log/maillog | grep warning" and I got these warnings. What they mean ? Should I be scared of them ?

Mar  1 09:07:10 mail postfix/smtpd[17350]: warning: network_biopair_interop: error reading 5 bytes from the network: Connection reset by peer
Mar  1 11:23:09 mail postfix/smtpd[18521]: warning: network_biopair_interop: error reading 5 bytes from the network: Connection reset by peer
Mar  1 13:01:26 mail postfix/smtpd[19668]: warning: network_biopair_interop: error writing 69 bytes to the network: Connection reset by peer
Mar  1 13:01:26 mail postfix/smtpd[19668]: warning: network_biopair_interop: error writing 69 bytes to the network: Broken pipe


Thanks in advance!

Upgrading to at least 2.8 should fix this warning message.

I actually can't do this from yum/apt.

Could you please help me upgrading it?
