[cobalt-users] Sendmail and ISP blocked port 25 question

["Eric Lowenbach" <ericlowenbach@xxxxxxx>]

Hi list,

I have a newbie question/problem I hope someone has a quick fix for. I just
set up a Qube 3 on my home network (which is cable provided by
Altrionet.com). I want to serve low volume web pages and a bit of mail, but
it looks like port 25 is blocked by my ISP. I plan to redirect smtp requests
to another port using the MailRelay service at DynDns.org (I have already
registered the domain www.fiddlehoney.com and have nameservers pointing to
my Qube).

The question is, how do I tell my Qube that I want to use a different port
for mail? I tried editing a line in /etc/mail/sendmail.cf from

DaemonPortOption=Name=MTA   to

DaemonPortOption=Port=52525,Name=MTA

This causes sendmail not to work (I believe it's version 8.10.2). Obviously,
I need more info. Does anyone have an answer?

Thanks,

Eric
