[Gllug] Qmail funniness

[Luke Hopkins]

I have an install of Qmail which is behaving badly.
The long and short of it is, it accepts mail nicely, but all deliveries
(local & remote) often take up to 40 minutes or so. I was wondering if
its waiting until the 'concurrencylocal/remote' are up to their limit
before it starts to deliver. Does Qmail work like this?
I've tried the Qmail archives to no effect. Tailing the
qmail-send/current just shows nothing for ages, then it bursts into
life. HUPing it also makes it burst into life.
My concurrencylocal concurrencyremote are both at 75 as we will be
handling quite a lot of mail.

Output from qmail-ctt is as follows:

concurrencyincoming: I have no idea what this file does.







Obviously names have been replaced to protect the innocent, but if
anyone has any thoughts on what might be the cause, I'd love to hear it.
Ideally what I want is for a message to hit the box, get delivered
locally immidiately, and the result sent on immidiately.
Could it be DNS (currently using dnscache)?

Thanks
Luke
