Hi comeanddance,

please change '25' in /sbin/init.d/qmail:

to

and restart qmail.
But remember: we will update this file soon (for RBL) and you will loose this q&d hack!

I just did a fast "lookup"...

http://www.exim.org/exim-html-4.10/doc/html/spec.html

Maybe you search the documentation yourself for your specific question...

Just answered a related one in "General":

on top of

/var/chroot-smtp/etc/exim.conf-default

put

smtp_accept_max = 5

then stop/start.

This will allow 5 concurrent SMTP connections. Surplus connections will be deferred with a 4xx.

Hi Tom,

thank you for the answer.
In our case it was a mailer daemon who tried to establish 50 concurrent connections for outgoing mail.
(Sending about 100-200 Mails from a delivery job several times a day).
We reduced him now to 5 concurrent connections...

Karsten
