E-mail problems

[Michiel_Gedopt]

Hi all
I am having email problems on my VPS with Plesk and I dont know what is going on.
I have 3 domains (sites) on it.
on 1 of them any e-mails I send are not working.

sending them to one of my other inboxes (not hosted on the VPS) i always get the following:

host [RECEIVINGDOMAIN].com[x.x.x.x] said: 550
"REJECTED - Bad HELO - Host impersonating [Problemdomain.com]" (in reply to
MAIL FROM command)


I only have this with 1 domain. the others are working well.
I have exactly the same DNS settings for all 3
I have SSL enable for my main hostname domain but the 2 others also use it.

any idea's?
many thanks

Check RDNS entries for the ip's sending the mails. It should be pointed to the sending domain.
