Reverse DNS does not match SMTP Banner
- by Bastien974
Hi all,
I had this Warning with mxtoolbox. I know that it's not necessarily a big problem, but since we are having lots of issue with email delivery, I want to check everything.
I have a Exchange server 07 + Sonicwall.
My FQDN is office.mydomain.ca for send/receive connectors.
When I try : telnet office.mydomain.ca 25 -- 220 MYSERVER.mydomain.local Microsoft ESMTP MAIL Service ready at Fri, 7 May 2010 10:34:36 -0400
I can change my SMTP Banner in the Sonicwall, but I don't know what to write, if there is a specific syntax or what can be the consequence if it doesn't work.
Thanks for your help.
