Sendmail Log

Hi,

I have sendmail configured for incoming mails in my network. On of the mails is giving message of source routing not allowed  and the mail retured back to sender

Following is the sendmail log from firewall

mblfw01:Admn {5} % cat /var/log/maillog | grep p8R3W75S027040

Sep 27 08:32:07 mblfw01 sendmail(1)[27040]: p8R3W75S027040: ruleset=LocalCheckUnqualifiedAddr, arg1=Undisclosed recipients:;, relay=mobismtp.link.net.pk [202.154.224.114], reject=553 5.0.0 source routing not allowed.

Sep 27 08:32:08 mblfw01 sendmail(1)[27040]: p8R3W75S027040: from=<muhammad.nauman@mobilink.net>, size=228813, class="0", nrcpts=1, msgid=<C2356E81DBC636458AA126B5EBEA00DC4AF30F9E@ISB-MAIL.mobilink.net.pk>, proto=ESMTP, daemon=MTA, relay=mobismtp.link.net.pk [202.154.224.114]

Sep 27 08:32:08 mblfw01 sendmail(1)[27040]: p8R3W75S027040: to=<raza.sayeed@meezanbank.com>, delay=00:00:01, pri=258813, stat=source routing not allowed.

Kindly explain what was the actual cause of this issue ?

Re: Sendmail Log

Follow the KB article I have attached to this message to allow these emails to pass through the firewall.
