Our Exchange 2003 server keeps getting blacklisted by means of
<mail.ourcompany.com #5.5.0 smtp;553 Bogus helo jdesk. <http://unblock.secureserver.net/?ip=66.XXX.XXX.XXX
I have contacted our ISP and setup reverse dns for our IP to mail.ourcompany.com. I have also gone under the SMTP virtuial server in exchange 2003 manager and set the FQDN to mail.ourcompany.com as described in:
But I do not beleive this have been configured correctly still. We keep getting blocked and I have ran SmtpDiag.exe from Microsoft and it still reports our mail server saying ehlo as ourcompany.com instead of mail.ourcompany.com. When I telnet to our server it welcomes me as mail.ourcompany.com.
Does anyone know if this discrepensy would be casusing us to keep being blocked?
I have changed our FQDN is in the "Default SMTP Virtual Server" to mail.ourcompany.com but it is still ehlo as ourcompany.com, does anyone know where I can change this?
