Hi there
I am having difficulty as our mails are not going on time to some of domains. With mxtoolbox it showing following error for SMTP diagnostics test.
SMTP Reverse DNS Mismatch Warning - Reverse DNS does not match SMTP Banner
SMTP TLS Warning - Does not support TLS.
SMTP Server Disconnected May be an open relay.
SMTP Banner Check OK Company Public IP address resolves to static-mum- Company Public IP address.mtnl.net.in
I configured FQDN as servername.domainname.com on default SMTP virtual server. Kindly guide me as I am new to exchange server.

Try out the following steps to Configure SMTP banner:
1. Start Exchange system manager.
2. Go to administrative group> Expand Servers>"YourServersName".
3. After that expand Protocals container then select SMTP container.
4. On the right window, right click the Default SMTP virtual Server (Or the name you set your SMTP Server) and select Properties.
5. Select the Delivery Tab> Advanced button.
6. Under the Fully Qualified Domain Name (FQDN) type mail.yourdomain.com (The A/Host record you created in DNS for your mail server)
7. Click Apply and OK.
