Well I don't except incoming mail other that an occasional return
receipt. But I did (for the dial users) include a line that maps the
'mail.ohiocounty.net' to the SMTP server. This also the dialin server,
ftp, www, etc. ...

I am thier ISP. However, (to apply this) I guess your saying this is
not nesscary since netaddress.com (a free email server) will be holding
