-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Speaking of port blockage, I know of at least three ISP's in my area that do this; more specifically, they intercept all traffic on port 25 and if it isn't destined to their own mail server, it gets bounced back as undeliverable. They even include a specific message telling you that it must be sent through their MTA. Cox high speed internet, the only high speed internet provider in my immediate area does this. I have several linux and windows machines at my house on a LAN, they all route mail to my internal mail host which runx Exim and I have Exim configured to smart host all outgoing mail to Cox and it all works well so far. Cox blocks even more inbound ports - namely FTP, HTTP, Telnet and 25 SMTP. They don't seem to block ssh port 22 though:). - -- HolmesGrown Solutions The best solutions for the best price! http://ld.net/?holmesgrown -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (GNU/Linux) iD8DBQFCE8l+WSjv55S0LfERAtQLAKCaNy62264Ai3XrzWZokO+ALhTokACg2G0C IYU/5XRcAAQGM8ILdnz7a/Q= =RgTp -----END PGP SIGNATURE-----
