temporarily rejected connection in “connect” ACL: “Host is ratelimited due to multiple failure only connections”

Sometimes you won’t be able to send/receive emails. Telnet may mention a temporary problem as follows.

telnet abc.com 25
Trying 123.456.789.12…
Connected to abc.com.
Escape character is ‘^]’.
451 Temporary local problem – please try later
Connection closed by foreign host.

Upon checking the error log, I noticed the following error displayed.

2013-07-24 03:11:48 SMTP connection from [122.174.199.157]:58121 (TCP/IP connection count = 1)
2013-07-24 03:11:48 no IP address found for host abts-tn-dynamic-157.199.174.122.airtelbroadband.in (during SMTP connection from [122.174.199.157]:58121)
2013-07-24 03:11:48 H=[122.174.199.157]:58121 temporarily rejected connection in “connect” ACL: “Host is ratelimited due to multiple failure only connections (7.9/1h max:5)”

To overcome this error, I did the following. This is a cpanel server.

/etc/rc.d/init.d/exim stop

cd /var/sppol/exim/db

mv ratelimit ratelimit.bak

mv ratelimit.lockfile ratelimit.lockfile.bak

/etc/rc.d/init.d/exim start

Asked the client to try again and it all worked. The ratelimit files will be generated again when exim starts processing.

    This was great advice except I noticed you misspelt ‘spool’ in this line:

    cd /var/sppol/exim/db

    Hopefully this saves someone else who is in a rush and doesn’t read the error…
