>>554 No ! in UUCP! (dave)

  This is caused by you providing a sender address to the UUCP mailer
which doesn't have a ! in it.  Sendmail wants to create a 'From '
line with:  From user date remote from host

and without a '!' it cannot find the host.

 Most likely cause:  You are trying to use domain notation 'user@full.dom.ain'
instead of UUCP notation: uunode!user  or full.dom.ain!user

 Solution:  Change your rewrite ruleset (the one specified in the 'S='
operand to the UUCP mailer) to provide the proper format.

 Alternate solution:  If you have a non-standard uux, or if your neighbor
really prefers domain notation on the UUCP mail envelope, just remove the
'U' flag from the 'F=' string of flags in the UUCP mailer definition.
Without the 'U' flag (the UGLY UUCP flag), sendmail does not add the
'remote from host' to the end of the 'From ' line, so does not search for
a '!'.
