I'd recommend choosing a port greater than 1024 as some ISP's have specific allow statements for ports less than 1024. It's not a common practice, but it may save you from having to change things later if your ISP decides to go crazy on the security front. kashani I met also a problem if Solaris is on other side ... try "echo 0 >/proc/sys/net/ipv4/tcp_ecn" noro -- gentoo-user@gentoo.org mailing list

Set it to listen to port 26 (instead of 25). A friend of mine who runs a small ISP has basically set this up as a permanent solution for his customers who are being blocked by their local ISP's. Those who use the SMTP server (e.g. myserver.net) will have to configure their mail clients to send on port 26. (Usually done like so: myserver.net:26) HTH! -- G a b r i e l M .
