Blade SMTP Server 550 5.1.1 User unknown Error
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:

Code:
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.

NAME

       calibre-smtp - part of calibre

SYNOPSIS

       calibre-smtp  [options] [from to text]

DESCRIPTION

       Send  mail using the SMTP protocol. calibre-smtp has two modes of operation. In the compose mode you specify from to and text and these are
       used to build and send an email message. In the filter mode, calibre-smtp reads a complete email message from STDIN and sends it.

       text is the body of the email message.  If text is not specified, a complete email message is read from STDIN.  from is the  email  address
       of the sender and to is the email address of the recipient. When a complete email is read from STDIN, from and to are only used in the SMTP
       negotiation, the message headers are not modified.

       Whenever you pass arguments to calibre-smtp that have spaces in them, enclose the arguments in quotation marks.
