I need to setup a SMTP sever only for the outgoing mails.
There should be no MX record for these servers so that there will be no incoming mails.
But I have the following queries.
1.If there is no MX record for this server & for the outgoing mails some of the receipient mail server will look for the reverse DNS record & for the valid MX record. So in this case there are chances that some of the mails will be dropped.
2. There are chances that SPAM mails will be targetted using IP address of the SMTP server.
I dont have Anti SPAM solution so in this case . So can i configure the SMTP server to reject any incoming mail to this server.
