Hi Kevin,
This is my first mail server set up, and I can say that I now have it up
and running and to be quite honest, I'm very pleased with the results.
It is sendmail I'm running, version 8.12.8-5.90. Despite what security holes it may have,
I'm kind of thrilled to have it working so well, even if it did give me a
bit of a headache initially.
I will have to have a google at the security holes found in sendmail, but
for now I'm just pleased that my 'project' has been successful. I've
installed ipop3 on my mail server now, and can send and retrieve mail from
it using Mozilla Mail with no problems. For someone like me, with just an
amateurs-eye view of computers, this is a real result. I'm going to have a
look at how ipop3 intergrated so well, without me having to do any more than
supply the connection details for the mail client to use.

Thank you for the information there. I went and had a play with BIND after
reading a bit about the Domain Name Service and A, CNAME and MX records.
Again, I ran into problems. Although the server appeared to be running, ie
it restarted no problem after any modifications, I noticed in
redhat-config-services that 'named' had 'rndc: connect failed: connection
refused' in the status box. I appear to have the rdnc.conf and the key
file, so I don't really know what's going on there.
I was wondering if I needed it (DNS), and I would welcome the benefits of
reducing any unwanted traffic on my 1024/256Kbps line, so I'll look into
the alternative you suggested.
Many thanks for your input.
Regards,
LLFormat.
