The port 25 block is pretty much standard for large ISPs today; it's to prevent spammers from using massive networks of compromised PCs to deliver spam. ISPs generally expect users to either a) use the ISPs mail servers, or b) submit email to some other site, which usually requires authentication. --Ken _______________________________________________ Nmh-workers mailing list Nmh-workers@nongnu.org http://lists.nongnu.org/mailman/listinfo/nmh-workers
