It replies with "abc Not Allowed" where abc is a SMTP fail code as soon as the bad IP connects. Most mail servers then seem to just drop the connection. Could it be that your mail server is rejecting your Mantis server IP for some reason every now and again? Are you using any DNS based blocking? Try adding the mantis server IP as an allowed to relay host if it isn't already. Not saying that's the problem for sure and I have never had such a problem with Mantis, but it does sound similar. Alternatively for some reason PHPMailer is simply dropping the SMTP connection because it doesn't like the response it got from the mail server. The result is the error you're seeing in your mail logs. HTH CH |
