Hi Zhang,

Today I started receiving many errors like:

May 29 04:38:06 mail postfix/smtpd[12264]: connect from unknown[209.85.210.46]
May 29 03:38:08 mail policyd: connection from: 127.0.0.1 port: 59845 slots: 0 of 2044 used

May 29 04:45:11 mail postfix/smtpd[12264]: disconnect from unknown[209.85.210.46]

What could be the issue as sender is sending E-mails from Google Apps?

Hi Zhang,

Do I need to update only the logrotate part from your reference?

Re: Postfix network_biopair_interop: error

Oh, sorry for the confusion. Not the logrotate issue.

I'm afraid you have to upgrade Postfix to at least 2.8.0 stable release to fix "network_biopair_interop" issue.

Re: Postfix network_biopair_interop: error

hi Zhang,

Actually I do not know how to upgrade it to 2.8 as my current version is:

mail_version = 2.5.9

Is there any document available for the upgrade in iRedMail? or actually I am afraid on doing upgrade from Googling as I might loose my running server.
