I am sure that would work, but as you know the more port 587 is published, it will be hit also...
Imail 587 refuses any SMTP command, including the RCPT TO and its vulnerability, if the SMTP session is started without an SMTP AUTH after EHLO. IIRC, about the only command port 587 accepts without a preceding successful SMTP AUTH is EHLO.
Imail 587 it won't even accept HELO because HELO says the SMTP protocol level will be basic SMTP protocol and therefore won't support Enhanced ESMTP service of SMTP AUTH.
Everybody should hack their registries to activate port 587. It absolutely can't hurt to have it on.
Then telnet into it to see how it behaves. Len To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/
