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
last portion.

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.
