2.2 sendmail: 553 host.iona.ie host name configuration error

Post by Justin Mas » Fri, 05 Nov 1993 02:35:50

Okay folks, sorry if it's a FAQ, but this has been bugging me quite
a bit...
What's up with this:

16:28:36 - 113 #...; /usr/lib/sendmail -v jmason

Quote:>Trying  connected.
>220 class.iona.ie Sendmail 5.0/SMI-SVR4 ready at Wed, 3 Nov 93 16:28:38 GMT
>>>HELO class.iona.ie
>553 class.iona.ie host name configuration error
>Trying  connected.
>[.... ad infinitum ]

Now, shouldn't a command-line invocation of /usr/lib/sendmail try to
deliver locally without trying to connect to its OWN port 25, or at
least try and connect to the real mailhost, or even to class.iona.ie's
MX-record host? Why is it so brain-damaged??! :(

I've applied the 101077-03 jumbo sendmail patch, and the same thing
happens with both main.cf and subsidiary.cf. I'm stumped. The -bt 3,0
ruleset testing works grand, and the rewriting is valid... mail from
other hosts works grand too. It's only local mail-sending that's stuck.

Anyone know?

1. Sendmail Host Name Configuration Error

Hi Everyone:

  I changed the return path rule so that it appears as              

seems to be sent but on host "innovation", I didn't receive any
new message. But if I looked at /var/mail, I found that root received
new message which points out that there is a host configuration

seems OK. Could anyone points out what's wrong with my host setup?
Thank you in advance for your suggestions.
