Mail with many BCC:s and delivery delays
I need a bit of behavior clarification for injecting a single mail to many recipients. If I send 1 message to 100,000 people using BCC:s, what happens if another such message is sent, or, for that matter, a regular (i.e. non-list) message? What I mean is, if qmail processes message in the order received, and it receives a message to 100,000 recipients, does that mean that it won't start sending the next injected message until the first is completely delivered? (or at least attempted and deferred?). Like with this list... Let's say Charles sends a message 1/10 of a second after I send this one. Does that mean that qmail won't even /try/ to send his until mine has been completely delivered? If so, how does anyone run both standard email accounts and large lists on the same box without experiencing HUGE delays on their regular outbound email? Sorry, I'm sure this is a FAQ, but I couldn't seem to find a clear answer in the archives. Thanks, --joshua.

I believe some people have run into this behaviour in the past. One suggested solution was to run separate instances of qmail for the lists and regular users -- i.e. /var/qmail and /var/qmail-lists . If you can have two IP addresses on the machine, you can then even run qmail-smtpd from each so each instance receives the proper bounces. Otherwise you have to play games of some sort.

By having more than once instance of qmail installed on your system or having your list run on a seperate system. Sorry, I'm sure this is a FAQ, but I couldn't seem to find a clear answer in the archives. I think a search for multiple instances or somesuch should do the trick. Regards.
