    Re: DNS or Firewall?

    Thanks.  At home I was using OE and that explains my problem.  I'll install PMail at home and see if it works.

    I will also turn on authentication in MercuryS and create the file to see if that solves my problem.

    I've got a number of domain names pointing to the same IP address.   In all cases I set an A record to the IP address and an MX record to the actual host name of the server.  Here's my domains section and you can use your NSLOOKUP tool to see what I have set for the domains in the DNS.  A couple of these are local only domains I use for testing and I have bolded these since they are not real domains.  I can access these domains from the outside via my router.  I use daemons and other tools to move the mail to internal servers where required.

    [Domains]
    stephens: stephens
    stephens: [209.128.94.2]    # external IP address
    stephens: mail.tstephenson.com
    stephens: tstephenson.com
    stephens: [192.168.1.2]   # internal IP address

    Riight.  I had sigs turned off.  Now I can see them.
