[Mailman-Users] Server Configuration..

this sucks! I've created a list of 100,000 subscribers .. SMTP_MAX_RCPTS=5,
throttle worked perfectly, 800 emails per minute.. the messages should be
delivered in a 2 hours time .. now it's 4 hours and 47,000 messages are
stuck because hotmail n yahoo are deferring ..
I read somewhere that the biggest list that's using mailman is 500,000 in
size.. is it really true or only 50,000 messages are going thru n the rest
is delayed or even bounced back..
I don't know what to do ... I did everything in the book.. our viewers had
subscribed to our lists with double opt-in .. mailman is properly
configured.. I don't know what yahoo and hotmail really want! I'm so
desperate and disappointed..

Regardless of why it happened, it comes across to others as shouting.

It's not terrific. At that rate, assuming everything had completely
left your MTA in that time, it would take between 17 and 20 hours to
deliver to 2 million recipients. Is that acceptable?
Also, it is not clear that just because Hotmail accepted all 5500
addresses out of 10,000, that they will accept the next 55,000 out of
the next 100,000 (if there are that many). Also, once Yahoo starts
deferring, their deferral rate will increase if you keep sending more,
and this will add to the load on your MTA.

I can't say. Perhaps the bottleneck is the bandwidth of your internet
connection. If so, increasinfg the ability to push more data faster
won't help at all.

The throttle.patch.txt file attached to this message contains a 2.1.9
version of the patch. The only difference is the line number of the
To install it, save the file and cd to your mailman installation and
give the command
patch Mailman/Handlers/SMTPDirect.py < /path/to/throttle.patch.txt
and then restart Mailman.
If anything goes wrong, you can remove the patch with the command
patch -R Mailman/Handlers/SMTPDirect.py < /path/to/throttle.patch.txt
followed by another restart of Mailman.
