You already can influence the number of outgoing connections:
/var/qmail/control/concurrencyremote
contains the number of concurrent connections open at any time - that is a good
value.
Correct me if I am wrong, but I do not see how QMT could benefit from patching
qmail in such a way as to make this more configurable as it already is (e.g.
allow for per destination domain type configuration, etc.).
You know, perhaps the question is this: what is QMT designed to do? It's a
full-fledged mail server suite designed and optimized to provide an alternative
to stuff like Exchange, etc. allowing for virtual domain and virtual mailbox
management so a multitude of users can read, write & exchange e-mail., using
qmail as its MTA. Neither qmail nor QMT have been designed to provide email
marketing functionality. They *may* be used to that end, but probably (like the
stuff I listed earlier) with exceptions.
On the other hand, if you ended up installing a system that was designed and
optimized to do email-marketing, I should not at all be surprised that while it
*could* be used to provide the Exchange type services mentioned above, it
probably would have some drawbacks.
Bottom line: This is not a one size fits all type situation.
