Missing suplimentry packages for Postfix on OS where they upgrade Postfix

PRODUCT, VERSION, OPERATING SYSTEM, ARCHITECTURE

Product version: Plesk Obsidian 18.0.63.0
OS version: AlmaLinux 8.10 x86_64

When we try to enable PCRE support for Postfix yum will attempt to downgrade Postfix because Plesk does not include the supplementary packages on OS where they upgrade Postfix.

STEPS TO REPRODUCE

Try to install the postfix-pcre package:

yum install postfix-pcre

yum install postfix-pcre

I already warned about this issue in the past:

Question - Do not forward spam emails to external mailbox

Hi, Some of our customers are using e-mail forwarding to their personal mailboxes like Yandex, Hotmail or Gmail. When I check our mail logs I see a lot of incoming spam to our servers (which are marked as SPAM, no issue there) But is there any way to deny forwarding for spam mails? At this...

Plesk should release the postfix-pcre package with the same version as the postfix version used in Plesk.

Thank you for your input. The report has been submitted to our engineers for a review.

Well it's good that Plesk does have PCRE support compiled in with their Postfix package. Maybe the simplest solution here would be to just add a dummy package for postfix-pcre so that postfix doesn't get downgraded if the customer tries to install it. Otherwise they could make it modular like the default OS postfix-pcre packages do using dynamicmaps.
