Port 993 is the SSL enabled port for IMAP .Mac access. If you have .Mac configured for POP use, then with SSL, you use Port 995. I have used these ports for years without problems with .Mac. I also use Port 587 for authorized SMTP access without difficulty. Norm --- Norman A. Cohen nacohen at mac.com "Washington is the only place where sound travels faster than light." C. V. R.
