Sourceforge introduced the 'callback' some moths ago. Check your logs (as you always should before posting...) and you may see a connect from there at the same time. If you dont see anyting it was probably because you server was unreachable like just now. mail1.americasnet.com has a delay of at least 30 seconds until the greeting appears and mail2.americasnet.com just sits there without any greeting at all for 2 minutes: # telnet 38.118.152.247 25 Trying 38.118.152.247... telnet: Unable to connect to remote host: Connection timed out You are probably using defunct dnsbl or something alike. Additionally the identical priority of your mx prevents a fallback, one good configured mailserver is still better than two messed up boxes ;) Roland ------------------------------------------------------- This SF.net email is sponsored by: IBM Linux Tutorials.
