And then what happens?
Does it eventually time out, do you get a network error, cannot connect to host, connection refused? If so, is your network connection flaky, intermittent, subject to disconnections, etc.?
Or, does it eventually give a dns error, about hostname not found? If so, is your dns server flaky, or your network connection to your dns server flaky?
Can you manually connect (telnet) to port 25 of the mail server, reliably, and reliably get back an esmtp/smtp greeting from it? Or are manual connection attempts just as flaky as your automated ones from your application?
