Mailismus won't start up. The log files claim it failed to find a licence.
n/a - Mailismus is now free and open source and no longer requires a licence file.
How do I route all outbound email via my ISP?
Like any SMTP server, Mailismus can of course send messages directly to their final recipient, but for various reasons (eg. company policy, or the fact that connections from your retail IP block might score lower on some spam filters than connections from a backbone ISP) you may wish to funnel all outbound email via a single point.
This can be configured via the /mailserver/mta/deliver/relays block in the mailismus.xml config file, which is documented in section §4.5.4 of the Admin Guide.
Say your ISP has advertised post.demon.co.uk as the outgoing SMTP relay, you would configure it as follows:
<relays> <relay address="post.demon.co.uk"/> </relays>
