2) I changed the max time in queue for any message
(outbound) to 35
minutes. This means the server will try to send email to you once,
then again 30 minutes later, and then it will just give up on you.
[...] But it won't try to send you any given list post more than
twice now.
How does a 421 greeting banner fit into this? Does that count as one
of those two rejections? If so, I need to set my subscription nomail
and subscribe another address, so as to get saner queueing behaviour.
(Otherwise, I'll lose list posts at busy times; any attempt to open a
connection from a host which already has a connection open draws a 421.
But if you're giving up on retries, that rather badly breaks the
assumptions underlying SMTP, and I care enough about list mail to be
willing to go to some minor lengths to keep it useful to me.)
For those sendmail inclined.... I considered setting
up a secondary
queue for slow delivery where any emails that take longer than X time
get moved to a low priority queue. Quite frankly, I don't want to
deal with it. I'd just get more complaints about posts being out of
order ;)
If that really is the concern, maybe make it a per-user option? I'd
certainly turn it on, and can deal with resulting reordering - but if
the actual reason is something more like "I don't have the time/energy
to figure out how to do this" and your comment is just humour, never
mind; I'll just do the other-address dance I sketched above.
If we can work out a way to feed it reliably, I'd be willing to host an
exploder sub-list for people who want more conventional retry behaviour
(and are willing to accept the resulting re-ordering potential), with
the resulting queue management becoming my problem.
