I recently setup a new server with plesk only to find that some machines fro 79.247.96.x scan it for open ports every other second.
There have been 40000 probes in the last 24 hours.
So I strongly favor a plesk addon against port scanningPeter supported this idea ·
There were some solutions for Qmail MTA in Plesk – https://talk.plesk.com/threads/how-to-setup-a-procmailrc-correctly.103810
In latest Plesk versions you can use modern Sieve mail filtering instead of outdated procmail. As you can see procmail support is not so popular feature here for many years, but if you request will be quite popular we will consider implementing this feature.
I had a look on sieve and I don't see it can replace procmail.
Sieve can do simple mail filtering but it cannot feed the mail to a pipe so that it can be post processed by other programs.
Thus I cannot trigger specific actions depending on mail contents.
So Sieve can do something but is not as sophisticated as procmail.
Thank you for your answer.
Checking on google for plesk and procmail I find quite a number of articles.
This shows to me that there is well demand for mail filtering with plesk even though it may not show up as popular on the plesk forums.
Regarding sieve vs. procmaiI found the following article https://lwn.net/Articles/416901/ which discusses the obsolescence of procmail
Nevertheless I will have a look at sieve to see if I can switch to that.
As far as I see sieve support is mainly for dovecot and I am on courier imap right now.
Can I switch to dovecot transparently or do I have to change/reconfigure e.g. my mail and/or mailman configuration?
