# yum install sendmail-cf

Edit /etc/mail/sendmail.mc and change:

dnl MASQUERADE_AS(`mydomain.com')dnl

to:

MASQUERADE_AS(`work.de')dnl

If you want to be able to rewrite "nagios" as "boom", you should also
add:

FEATURE(`genericstable',`hash -T<TMPF> /etc/mail/genericstable')dnl

just below the existing line:

FEATURE(`virtusertable',`hash -o /etc/mail/virtusertable.db')dnl

Then create a file /etc/mail/genericstable containing the line:

nagios		boom at work.de

Then run "make -C /etc/mail; service sendmail reload"

I think that should do what you want.

Paul.
