Configure QMail to use a Smarthost
Routing all mails to a smarthost
The file where
SMARTHOST relaying to smarthost settings are kept is named smtproutes
and is usually found in /var/qmail/control/. We use the hostname
'mxpool1.spamgateway.comodo.com' (EU
based server) and
mxpool1.us.spamgateway.comodo.com
(US
based server)
on port 587 as
outgoing server:

echo:
mxpool1.spamgateway.comodo.com:587" >
/var/qmail/control/smtproutes
United
States
echo: mxpool1.us.spamgateway.comodo.com:587"
> /var/qmail/control/smtproutes
This
command will set qmail that all your mails will be routed to
mxpool1.spamgateway.comodo.com:587 ormxpool1.us.spamgateway.comodo.com:587
according to your preferred routing (will
remove other existing lines).
