Filter customer info from Reply-To in mail header

[L8EK]

sorry for maybe trivial question but i'm new to otrs

i want to use otrs to handle our (my company) internal emails (so no customer base, sender=customer) but knowing my users i know they will send some problems to my mail adress (instead of sending it to helpdesk@domain.name)

in this case i want to resend that mail straight to otrs, adding to mail (header) field Replay-To with original sender

how can i set PostmaterFilter to set cutomer info from Replay-To field?

i even have regexp to search First Name and Last Name ([A-Z]\S+\s[A-Z]\S+) and Mail ([\w%-\.]+@[\w\.-]+\.[\w\.]{2,9}) but i can't get it to work
another case is how to set all customer info, not just the mail - in filter options i see only X-OTRS-CustomerUser and from what i read is only for email

thunderbird has a redirect plugin that does better than set Reply-To
