How to edit incoming email directly on the mail server?

Question

Email

It is necessary to correct the subject of the incoming letter, add the ticket number according to the condition.
The sequence of actions is as follows:
1. The sender writes a letter to our mail.
2. The mailbox on the server is pre-processed by the script, ticket numbers are put down, according to the condition.
3. The recipient receives the mail, and it already has ticket numbers.
Are there ready-made solutions for this or is there a specification for such a call to the server?
There is a similar plugin for chrome https://chrome.google.com/webstore/detail/signal/d... - but you need to make your own application.

Answer 1

It seems you want to reinvent the wheel.
There are ready-made SDs, where the processing of an already received letter is carried out and a ticket with a number is created, according to the keywords in the letter, it is already assigned to a specific group of performers, and already the performers receive a letter with the number of the ticket assigned to them.

usually similar processing does on local delivery of the letter. You can write your own Mail delivery Agent (MDA), which will stand between the MTA (mail transfer agent) and the "real" MDA (mail delivery agent), will receive a letter from the MTA, process it and transfer it to another MDA. Look, for example, at the descriptions of procmail and maildrop, perhaps you will find there, if not the necessary functionality, then an understanding of how to organize it.
