Hi, I am in the process of moving to a new VPS with DirectAdmin (I am switching to a new hosting provider, the old VPS also uses DirectAdmin) and I am trying to get everything set up and working. Some information first:
-OS: CentOS v7.0
-DirectAdmin version 1.51.3
-Exim version 4.88
The problem I am dealing with is that one of the sites I am hosting uses the DirectAdmin E-mail forwarder functionality. The e-mail should be forwarded to a Gmail address. On the old server, this worked fine, however on the new VPS I am having a hard time to get it to work.
I think I have the general mail settings set-up as it should, the VPS has an IPv4 and IPv6 address and reverse DNS has been set correctly. I have correctly set-up SPF and DKIM and do not have any problems when sending e-mail through a mail account on the server to any external mail address (e.g. Gmail). I have checked with mail-tester.com and get a 10/10 for e-mail that has been sent from a mail account on the server.
I've read that the problem with using forwarders is that the header needs to be rewritten in order to avoid problems with spam detectors on the receiving mail server. Therefore I have installed SRS (through the DirectAdmin SpamBlocker 4.5 package). As far as I can tell, SRS is working as it should and the headers of mail that has been send through the forwarder are correctly rewritten.
However, when I try to send an e-mail to the forwarder that leads to a Gmail account, my mails get bounced immediately. I always receive the same error message from the Gmail server:
Up to now, I do not have a clue what else I can do to get this to work. Therefore, any help or suggestions would be appreciated.
BTW: forwarding to any mail account other than Gmail (even sending mail FROM Gmail) works fine.
