Linux VPS: Email Error >>

[Maggie McPherson]

Hi

I've a Cpanel running Linux VPS, when I try to send an e-mail particularly to *@test.com an I get error as:

This message was created automatically by mail delivery software.
A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:
*@test.com
"R=static_route_hostlist T=static_smtp defer (-53): retry time not reached for any host"

Hello Maggie,


Make sure your domain is not blacklisted by any of the RBL's

if you are sure your mail server IP is not blacklisted.. what this error message means that all hosts to which the message could be sent have been failing for so long that the end of the retry period (typically 4 or 5 days) has been reached. In such case, exim still computes a next time to retry, but any messages that arrive in the meantime are bounced straight away.

After digging allocate I found, that one possible reason for this error is recipient mail server IP address being blocked in exim database.

Please follow these steps to resolve this issue..

root@server[#] cd /var/spool/exim/db
root@server[#] grep xx.xx.xx.xx * -R
ratelimit
retry


Where xx.xx.xx.xx being the IP of mail server.

So now we are sure that the Ip address or recipient mail server is blocked in the exim database.

Now to release the IP you should

1. Take backup of “/var/spool/exim/db/” directory
root@server[#] cd /var/spool/exim/
root@server[#] cp -ar db/ db-backup/

2. Stop exim service using following command

root@server[#] /etc/init.d/exim stop

3. Now delet the ratelimit & retry files
root@server[#] cd /var/spool/exim/db/
root@server[#] rm -rf ratelimit
root@server[#] rm -rf retry

OR

root@server[#] rm -rf *

4. Start the exim service

root@sever[#] /etc/init.d/exim start

As the service is restarted, it will rebuild the Exim Database..

Now you shall not face this issue with the e-mails
