Hello All,
I am currently running a Solaris 10 machine as inbound SMTP server i.e. bringing Emails from outside into our company. In /var/spool/mqueue , I have mails that are pending for the past 4-5 days. They are not being delivered and are causing my mount point size to increase.
Error type is:
Final-Recipient: RFC822; xyz@my-domain.com
Action: failed
Status: 5.1.1
Remote-MTA: DNS; [172.21.8.35]
Diagnostic-Code: SMTP; 550 5.1.1 User unknown
Last-Attempt-Date: Sun, 29 Dec 2013 23:02:21 +0500 (PKT)
Let me state that this is only occurring for Email IDs that DO NOT exist in our domain. Emails IDs that have been wrongly typed or so.
Is there some sendmail configuration that I can do that can DISCARD such Emails and not pile up in my /var/spool/mqueue.
Help.
