[otrs] Feeds mails to OTRS via HTTP(S)

Hello, In my test environment I have OTRS installed which I feed through a procmail filter which pipes the email to PostMaster.pl (used the .procmailrc.dist from OTRS package for that). In my production environment I have separate servers for email and for OTRS. So I can filter incoming mails with procmail, but I don't have access to the PostMaster.pl script because it's on another server, so I can't pipe to that directly. I don't like the idea of PostMastDaemon.pl, I don't want to run daemons for every OTRS installation. Because the server already runs a webserver for OTRS, I would like to feed the mail to OTRS via HTTP(S). Has anybody tried this before? Can it be done? Regards, Richard
