I am running A recent build of Postfix on a Gentoo server- I am pretty
sure it is about 3-4 months old. The problem I have is that the line the
mail is sent out on is buggy- I get lots of packet sequence errors, slow
speeds, etc. I need any advice I can get on configuring fault
tolerance-type options. This is a simple setup, and I am not talking
about clustering or failovers, simply how to set things so that things
that time out get retried a few minutes later, possibly several times to
mitigate the middle-of-the-day traffic rushes, as well as other network
spikes. Does anyone have any suggestions as to retry options, timeout
values? I am relatively inexperienced with MTA configuration, but I have
managed to get a couple of MTA’s working in the past. Thanks!
The defaults should give pretty good performance with good
tolerance for a flaky connection.
If you find the defaults insufficient, here are some relevant
docs:
http://www.postfix.org/TUNING_README.html#hammer
http://www.postfix.org/QSHAPE_README.html#queues
Just as general info, if the connection stays active but is
really slow (regardless if it's due to bandwidth or
transmission errors) mail should keep flowing and the default
settings should work well.
If the connection drops frequently, mail will be deferred and
may have trouble ever getting delivered. There isn't a good
workaround in postfix (or any MTA I know of) for a connection
that drops frequently.
