Problem forwarding emails hosted on another Plesk server

[Jay Versluis]

Hi there,

I've run into a problem where email forwarding from one Plesk server doesn't seem to work to an email address hosted on another Plesk server. Have you heard of this before?

Let me explain:
so I've got [email protected] hosted on Plesk Machine 1, and this email forwards to [email protected]. [email protected] is hosted on Plesk Machine 2 and is setup with a mailbox. It works fine when I send mail directly to [email protected], but emails get rejected when they get forwarded from [email protected].

Likewise, if I switch off forwarding on [email protected] and turn it into a mailbox then mail will arrive in said mailbox.

If I turn forwarding on [email protected] on again, remove the mailbox and instead forward mails to my Yahoo account the forwarding works fine. However, if I then redirect the forwarding back to [email protected] they don't arrive there.

Any ideas? What am I missing?

Hello Jay,

If you would send email from domain1.com (i.e. through webmail) to [email protected] - would it work?

I think the issue is a relay issue. could you check your maillog file using

tail -f /usr/local/psa/var/log/maillog

on the domain2.com server while sending a mail to domain1.com with forwarding enabled.

Is domain1.com configured on the second server? This could cause the relaying issue, too.

Try again

Send the mail to forwarding mail boxes from first destination and see the result if arrived Instantly and check machine 2 plesk Qmail logs.

Plesk Knowledgeable are here.

Something else to look at...

Do you have any kind of spam filtering enabled on the server2 mailbox?

If you do, maybe try adding the domain1 to the server wide white list on server2 and try sending again...

If you have spam filtering enabled, are you using any DNSBL services. Maybe your server1 IP has been listed for some reason. You can check here

Also, do you any kind of SPF rules active
