The clue is in the error message 'relay access denied'. Spymac isn't running an open relay (a good thing, as it's a spammer's paradise otherwise). Presumably the server has a list of acceptable TCP/IP addresses (or netmasks) it will accept mail from, and your machine isn't on that list. Alternatively, I'm talking from an orifice not normally reserved for communication, and someone who knows more will be along in a minute. Steve S

The IP for spymac.com is 213.218.8.109 the 'MX' for spymac.com is mail-in1.spymac.net which has an IP of 213.218.8.221. So when you connect to a mail server at spymac.com and ask it to deliver mail to a spymac.com address it must relay that mail to the mail-in1 server, and it won't do that from just any old IP address. Hence the SMTP error. Try connecting to the other SMTP and see what happens. BTW your SMTP conversation should start with a 'HELO' or 'EHLO'. Paul
