Here it is almost 2 hours later and those messages are still not out yet!

I forgot to mention in all of this that regular email to and from the
system works fine.   Emails to and from this Gmail account go back and
forth in just a few seconds.

Hmmm, now, this is one thing that does change on my system.   I use
Postfix and do helo checking with a file of spammers to reject.   I
add a few entries to that file every month (maybe 3 or 4 at most).  At
present there are only 72 entries in that file.   I also do general
RBL checking which could well be also taking place from MM to Postfix.
  I'll have to go have a look.   But it has been like this for years -
at least 3  years since I last went through my Postfix config and
tweaked it.  The only change since then is spammer domains going into
my helo_access file.

mailman at heimat$ ls qfiles/in/ | wc -l
       8
mailman at heimat$ ls qfiles/out/ | wc -l
     332

OK, I'll give that a try.

Will do.  I had been searching on a number of terms, but not that one.

Thanks for your time!
