> What IS a reliable way to check the hostname that IP is sending? (a) With IMail in particular, just know what virtual host is sending; (b) with any SMTP server, look in the logs.

"Respond" is not the usual term for a HELO, even if it technically is a response to a remote server's 220. IMail will use a different HELO depending on the originating virtual host, as stated several times already. > Is it this hostname that some remote servers will try to match the > reverse DNS to? Only those run by fools who are content to reject mail from any virtual hosting scenario with per-host HELOs. > Finally, how do I change the hostname that Imail is sending so I can > make sure it matches the reverse DNS entry? You can't have _every_ virtual host on a box match the PTR entry. That's impossible. You need to make sure that every host name (and therefore every HELO) has public A record pointing back to the server IP. --Sandy ------------------------------------ Sanford Whiteman, Chief Technologist Broadleaf Systems, a division of Cypress Integrated Systems, Inc. e-mail: [EMAIL PROTECTED] SpamAssassin plugs into Declude! http://www.mailmage.com/products/software/freeutils/SPAMC32/download/release/ Defuse Dictionary Attacks: Turn Exchange Addresses into IMail Aliases! http://www.mailmage.com/products/software/freeutils/exchange2aliases/download/release/ 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/
