I realize this is sorta off topic but my searches using Google have got me mostly no where. So I thought I'd ask here as there is a lot of _past Postfix_ mail handling issues discussed.
The issue is; I have to deal with a lot of messages that come from MS Outlook users and sometimes they are replies to replies to replies ... My reading indicates it has a little to do with HTML composed messages and the format=flowed declaration.
This produces messages with *lot* of extra line feeds. Makes the messages nearly unreadable -- in Thunderbird. I'm sure others have got two line (sentence) messages that took 6+ lines to display. Then when they are replies or forwards it is even more. Every line gets two NLs/CRLFs.
Anyone have a suggestion of how to _strip_ multiple line feeds from a message? Is there a sieve method/way? I don't want to fiddle with all the users emails just my own.
Pointers, ideas, clues?
