Unknown SMTP email redirection Loop Error in mail.log
 03-31-2015, 07:51 PM (This post was last modified: 03-31-2015, 07:52 PM by Good One.)
Hi,

I am not an expert on this to understand what causing it but I had done several modification on my sentora installation and server. Like Installed postfix, amavis, spamassassins configuration, fail2ban.. I am running ubuntu 14.04 minimal.

But now I am having a problem which generating in mail.log, I got notified about this by server admin. He told me that there are many Active SMTP connection.

and when I check my mail.log I see that it is doing redirect loop on my server and some of many delivery temporarily suspended errors. Huh

I can use roundcube to send and receive email from other services (gmail, hotmail etc). But it is showing this error and active connection for loop, which I am very unfamiliar with.

Kindly please help me solve this problem please. Below I am posted main.conf , master.conf, mail.log

No,

I have modified it by following this guide:

https://help.ubuntu.com/community/PostfixAmavisNew

and

additional adjustment on main.cf:


Code:
# Limit Active SMTP Connection

smtpd_error_sleep_time = 1s
smtpd_soft_error_limit = 10
smtpd_hard_error_limit = 20
smtpd_client_connection_count_limit = 10
smtpd_client_connection_rate_limit = 60

You need to list all the modifications and post the new config files. We can't evaluation the guide only as you might miss a step and end up with errors.

I have already resolved this problem yesterday. And emails are working fine so far, no more errors and no emails getting missed.

I had used same topic description into another forum for help also. Because that was enough for understand. I had added main.cf, master.cf and mail.log and problem was about email error in mail.log , Where some emails wasn't getting received because of finding no destination host.

What I had to do to fix it?.

Answer: I needed to include cpanel.mainwebhosting.com in line mydestination for /etc/postfix/main.cf


Hopefully this may comes in handy for other Smile
