greylisting filter Wrong HELO hostname localhost.localdomain

[tech01]

Seems this started when upgrading to a version of 12. It was working a few days ago and only seems to affect mailing lists. I found a google Cached thread here where Igor was assisting some folks as late as Aug 4 and referenced this was "reported to development (PPP-10678 for your reference)" it seems the forums on Parallels changed or something because several Google links are not working and resulting in having to used cached results for the two links below.

I am able to disable SPF and the e-mails go through just fine however this was working with SPF enabled before a recent upgrade.

This is the error message displayed in /var/log/maillog

I also had to disable the server-wide greylisting spam protection for this to work.

I can say that fix for bug PPP-10678 will be included to upcoming Plesk 12.1 version.
