Are you sure CableOne does not filter outgoing port 25 connection attempts to any servers save it's own relay? My ISP (A big name DSL provider; grep the headers if curious) does not perform incoming port filtering, but rather aggressively filters outbound TCP port 25 and (for reasons unexplained) 4444 as well. -- Fuzzy love, -CyberLeo Technical Administrator CyberLeo.Net Webhosting http://www.CyberLeo.Net <[EMAIL PROTECTED]> Furry Peace! - http://wwww.fur.com/peace/ _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
