Greetings,
I've been digging through the docs and can't find any reference to
adjusting the max number of incoming SMTP connections on the toaster--we
have started seeing brief periods of time where these are maxing out, and
I'd like to raise the cap.
Also, while migrating users from our older toaster machine to our newer
one, we've run into a strange issue where one particular client can POP
mail from our toaster, but can't send through it from their office LAN
(which was working fine on the older toaster).
Sending mail through the newer toaster works fine for this client from
anywhere outside their LAN; the LAN is behind a NAT FW, though we've
confirmed that the neither the FW (or their upstream ISP) are blocking
outgoing port 25 to anywhere.
Meanwhile, multiple other clients on the newer toaster are not having any
problems with sending or receiving mail--just the one.
Any suggestion/ideas would be greatly appreciated.
if you're using the firewall provided by qmailtoaster.org then it blocks
private IP addresses. Might be worth looking into.
As far as increasing the number of smtp connections - look at
/var/qmail/control/concurrencyincoming to adjust that:

You may also want to look at increasing your mysql connections as well,
as by default I think it's set at 150 or so.
