-Rt0 switch stopped functioning after 8.1.1 upgrade

eugenevdm

Regular Pleskian
Just upgraded from 8.1.0 to 8.1.1.

In the past we've used the switch -Rt0 for server_args in /etc/xinit.d/smpt_psa in order to speed up connections to our e-mail server that come from non-reversed connections, as per Plesk Knowledgebase article 298:

http://kb.swsoft.com/article_22_298_en.html

We really have to use this because not everyone who connects to our server has a reverse record, especially from our internal network where it's all private IPs.

But now this setting does not work anymore! Please could someone shed some light?
