I am having problems with mail on my new plesk 10.1 installation:
I have two IP based sites setup in my plesk, lets call the two IP numbers IP_1 and IP_2. When I send out email from the first IP_1 site some foreign mail servers reject my messages and qmail tells me the reason is that I lack a reverse DNS entry for IP_2. Here is an an example of a bounce where I have replaved the real IP number with IP_1/IP_2. My original message was sent from IP_1 and bounced with a message back like this:
x.x.x.x does not like recipient.
Remote host said: 550-Inconsistent or no rDNS record for IP_2 (see RFC1912 2.1)
550-http://www.ietf.org/rfc/rfc1912.txt
550-Reverse DNS record and matching forward entry must exist.
550 => wrong configuration at sending server IP_2
Anyone have any idea what can be the reason for this? I don't understand how emails from IP_1 can in any way generate a bounce due to IP_2. IP_2 does indeed lack a reverse DNS entry right now, but how on earth can that affect emails sent from IP_1?
DNS and I have never been good friends :-(
