Re: Same sendmail.cf files in different machines, cause different RULE EFFECTS

Thanks Rob, you're right.

My problem is that from sebs059 the field FROM sended is empty, and it
doesn't occur with sebs053, it is due to the difference between the
rules, why? I don't know.
I don't have sendmail.mc files, only subsidiary.cf files, I attach
these, you can see the versions in them. About operating system:

Machine hardware: sun4u
OS version: 5.8
Processor type: sparc
Hardware: SUNW,Ultra-60

I've compared the sebs059 an sebs053 ones. The sendmail.cf are minor
differences, and no differences with rules 11 and 31 but...........TAKE
A LOOK! Why?

Please post the sendmail.mc files these were created from, not the .cf files.

It would help significantly if you actually said what your problem was...

Please remember to provide details of the operating systems and versions of
sendmail.

This is the captain. We have a little problem with our entry sequence,
