Header Regex Match: Some headers don't work for regex filters

[masscream]

I have asked this question in https://github.com/RealRaven2000/FiltaQuilla/issues/115 , but probably it was dedicated to another problem...

I am trying to filter out Outlook calendar meetings by content-type "text/calendar" header. However so far I have not been successful. When setting up the filter I tried following options:

content-type:/\b^text\b/
content-type:/\b^text\/calendar\b/

I also tried adding it into mailnews.customDBHeaders in the format:

"content-type".
"content-type"
content-type
Content-Type

But the filter is still ignoring these events. I have found no other info, how to achieve this (except of broken java script). Any ideas? Thanks

I also tried adding it into mailnews.customDBHeaders in the format:

"content-type".
"content-type"
content-type
Content-Type

that may not be the right place to add custom headers. You should be able to add it via the uI:

In the conditions column, please select "Customize..."

then add the string content-type. (no quote marks)

From what I see, this is not added to the config setting mailnews.customDBHeaders - then I would just try the value

content-type:text\/calendar

I don't think you need the word boundary anchor \b as I guess this the full header value in this case.

Minor Edit: I had to add the code property above because otherwise the backslash is being swallowed. Make sure you look at this on github and not just in email.

The option Customize or Custom header works only in case the header is unique in the msg and does not have more occurences. Besides it's not a part of the FiltaQuilla plugin and does not work with RegEx at all (or at least I think). Therefore this is not working, that's why I tried filtering via body RegEx, but this is not working either. The exact phrase I need to match is "Content-Type: text/calendar" or just "text/calendar", however these Header/Body Regex filters are omitting both.

Content-Type: text\/calendar
text\/calendar

edit: I think it would be great to look also in the whole msg source, because as far as the msg can have multiple instances of the one header and/or multiple bodies, it's pretty difficult to say if the msg regex filter should be for header or body. I tested today couple of similar filters but none of them really successfully.

Header Regex:

content-type://i - printed out all msgs
content-type:/multipart.*$/i - none
content-type:/^text.*$/i - none
content-type:/text\/calendar/i - none

Body Regex

/content-type: text\/calendar/i
/^content-type.*$/i

I am not sure Header Regex works at all. Because nothing worked for me, I tried simple tests:

Subject://i - selects all messages Subject:/.*/i - selects all messages Subject:/.+/i - selects NO messages

Is this the expected behavior? Would that mean that the string to be matched is always empty?
