The question you should be asking is why it sometimes taking mail.borken.com more than 10 seconds to respond to a connect with a banner and exit after a QUIT command. Is this a busy server? Do you use anything like greet-pause on it? As previously mentioned, the mail logs on that server might provide some insight but also running check_smtp from the command line while it's happening (with -v) might be helpful. Also telnetting directly from the command line might prove informative... $ telnet mail.borken.com 25 Trying <ip>... Connected to mail.borken.com (<ip>). Escape character is '^]'. 220 mail.borken.com banner; Sat, 8 Mar 2008 09:09:44 -0600 quit 221 2.0.0 mail.borken.com closing connection Connection closed by foreign host. $ -- marc ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
