Dear Plesk,
An costumer of our corporation uses an externtal Spamexperts server and not the extension for Plesk. Sometimes its working just fine but the costumer says sometimes the email is rejected by the SPF on our server. The costumer do not know this but I can see this in our log file when I connect with SSH.
The problem is that the SPF check is reacting on the sender@domain.nl SPF record, he expect the *.antispamcloud.com in the sender@domain.nl SPF record. This is not possible because every sender@domain.nl that sends mail to this receiver@domain.nl will need the *.antispamcloud.com SPF record in their DNS settings.
I also added Spamexperts delivery.antispamcloud.com on the whitelist of Postfix (see: How To Whitelist Hosts/IP Addresses In Postfix).
This also doesn't work, I don't see any option in Plesk to add domains or wildcard domains to the whitelist so that the SPF wil bypass this domains.
Is there anything I can do because the costumer can't receive some email now because the SPF is rejecting Spamexperts on our server.
Please let me know what I can do about this problem so I can bypass SPF check for Spamexperts delivery servers.
Cheers,
Dennis de Jong
