Where does mail to postmaster go?
Question asked by Kerric Tratt - 2/28/2014 at 10:10 AM

Running SM Enterprise 11.7.  I'd like to know where mail for postmaster@ goes?  I had a situation where mail was being sent by default to postmaster (from Declude).  During troubleshooting I manually created a 'postmaster' alias and pointed to a local account, and mail addressed to postmaster was delivered fine.  After removing the alias, mail was still being accepted for postmaster, but I have no idea where it's going.  The domain in question has one user as Primary Administrator, but the postmaster messages are not going there.  I sent a message directly to postmaster to see if I'd get a bounce, but it was accepted and written somewhere:
 
10:32:36 [XXX.XXX.XXX.XXX][50497403] cmd: MAIL FROM:<jerry@foo.com> SIZE=9516
10:32:36 [XXX.XXX.XXX.XXX][50497403] rsp: 250 OK <jerry@foo.com> Sender ok
10:32:37 [XXX.XXX.XXX.XXX][50497403] cmd: RCPT TO:<postmaster@foo2.com>
10:32:37 [XXX.XXX.XXX.XXX][50497403] rsp: 250 OK <postmaster@foo2.com> Recipient ok
10:32:37 [XXX.XXX.XXX.XXX][50497403] cmd: DATA
10:32:37 [XXX.XXX.XXX.XXX][50497403] rsp: 354 Start mail input; end with <CRLF>.<CRLF>
10:32:37 [XXX.XXX.XXX.XXX][50497403] rsp: 250 OK
10:32:37 [XXX.XXX.XXX.XXX][50497403] Data transfer succeeded, writing mail to 160834094.eml
10:32:37 [XXX.XXX.XXX.XXX][50497403] cmd: QUIT
 
Any help would be appreciated.  Thanks.

POSTMASTER@, and ABUSE@, are both required accounts for every domain hosted.  Both accounts must be monitored and responded to by the MX server operator.
 
You have to setup a POSTMASTER account, for each domain, point it to a working account, monitor it, and respond to inquiries.
 
You also have to setup an ABUSE account, for each domain, point it to a working account, monitor it, and respond to inquiries.
 
An ALIAS can be used in lieu of a user mailbox to save licensing fees, if required.
 
RFC 822, RFC 1123 and RFC 2821 require that all domain's mail servers should accept e-mails to POSTMASTER@. To be compliant you can create an alias and forward all postmaster's e-mails to a valid mailbox.
 
RFC2142 requires that all domain's mail servers should accept e-mails to ABUSE@. To be compliant you can create an alias and forward all abuse's e-mails to a valid mailbox.

I know every domain we create we make these and a few other aliases. It would be nice (feature request!!!) to have a template option to auto-create this within the administrative interface.

John, can you start a new idea thread based on your comment. It is a very reasonable feature request. Having it as a separate idea thread will facilitate development tracking and have greater community visibility. As it is I am adding it to our features request list for further discussion by the dev. team.
