[Users] SMTP Failure on First Attempt to Send

[Charles Lipton]

After Rsynching my entire Debian 8.5 home directory to a second HDD in
anticipation of changing virtualization software, Claws could not find
my Address Book.  I erased all old Address Books, which was no
great loss, and I had to re-set ClamAv and Bogofilter to remove
all Receive issues. 

However, for the past week, every attempt to Send, regardless of the
recipient, results in an SMTP Failure notice.  Clearing the warning
message and clicking Send a second time results in a successful message
send. Log files seem to be the same each time.  I've edited out machine
name and recipient address.
