I've tried /.forward and /etc/mail/aliases, inserting an alias for root.
Just wondering if anyone has hit this wall before and was able to devise a way around it. For now all our EMS, omniback notifications are failing.
Thanks
Solved! Go to Solution.

Re: Sendmail by Root, blocked by Mail Server
In simple terms, tell your security "people" to knock it off!!!

Re: Sendmail by Root, blocked by Mail Server
I agree with Chris. Go to the Security geeks and tell them how much trouble their restriction is causing you. If that fails, I would start calling them EVERY time you have a failure that you would have been notified by via e-mail. Sometimes people don't appreciate our efforts until their phone rings at 3:00am. ;)

SolutionInstead of running errors to mailx, I created text files and did an su -c mailman "/usr/contrib/bin/mailout"
The script just sends an email with an ascii attatchment.
Since you already had mail coming off the server, you're in good shape and need not check /etc/nsswitch.conf and dns configuration.
It's annoying, but thats the way it goes.
Our smtp server won't forward mail that where it can't authenticate the DNS as a valid domain on the public internet. Our servers fully qualified domain names are not registered, specifically so if theres a firewall failure, theres still no way for anyone to mailbomb us.
As stated by others, your security people went over the top.
Email the error logs to upper management, or if you have a help desk, open a help desk call for every failed email, they won't be able to resolve the call without easing up on the security.
If your help desk is like ours, their batting average(average time from call to resolution) will quickly fall, and you will gain allies in your fight.

in sendmail.cf.
The genericstable file has the format
user differentuser@newdomain.com.
To "compile" the file:
makemap dbm /etc/mail/genericstable < /etc/mail/genericstable
As an alternative, if you control the program sending the nofications, rewrite the head of the e-mail (e.g. mailx -r diff@diffdomain.com)
