The original query was:

>>We recently upgraded from OSF 3.0 to DU 3.2c, and are now seeing
>>strangeness with the UNIX style From line (first line in the message
>>after delivery). On local delivery and delivery from some systems, it

>> From SomeRealUsername
>>
>>where SomeRealUsername has real significance relating to the sender
>>of the message. However on some email the line looks like:
>>
>> From daemon
>>
>>I have not been able to change it, even when I installed sendmail 8.7.1,
>>which leads me to believe that the problem may not be with sendmail at

Thanks to Greg Couch for the solution:

The problem seems to be with /bin/mail not believing the -r flag
when invoked by daemon -- the sendmail default. I added an S to
the local mailer flags so that sendmail would set its uid to root
before invoking /bin/mail, and that solves the "From " line
strangeness.

I also had replies from Arrigo Triulzi and Johannes Grosen stating that
they had seen the same phenomenon after the upgrade.

Thanks to all!
