F=Z
Apply DialDelay option’s sleep V8.12 and later
The DialDelay
option (DialDelay on page 1007),
if set, allows sendmail to try
to connect a second time if the first connection
attempt times out or fails. This option is intended
primarily for dial-up connections, but it can also
be useful if your fast connection is very
busy.
Prior to V8.12, setting the DialDelay option caused it to be used
by all delivery agents, even those for which it made
little sense. Beginning with V8.12, the DialDelay option only
affects delivery agents that have this F=Z delivery agent flag
set.
You can add this to a delivery agent with the MODIFY_MAILER_FLAGS mc configuration macro:
MODIFY_MAILER_FLAGS(`SMTP', `+Z') ← this must be MAILER(`smtp') ← before this
Here, we add the F=Z delivery agent flag to the smtp delivery agent. As
with all modifications of delivery agent flags, the
modification must precede the MAILER declaration of
the delivery agent.
