It's better to use `A .ics` to avoid attachments which happen to include 
`ics` in its name.

If possible, send me an example via “Help ▸ Send Feedback”. You 
can also use “View ▸ Show Raw Message” and locate the 
`Content-Disposition` header and the `Content-Type` header of the 
calendar attachment. These are likely all I need to figure out why this 
happens.

There might be an issue with MailMate not looking at some specific 
variant of specifying the filename. The filename indicates that MailMate 
could not find the name (or there is no name) and gave it a default name 
of `Attachment.ics` based on its MIME type. In that case, it's hard to 
search for. I think maybe this would work:

	Content-Type ▸ Subtype is “calendar”

For which you need to enable the “All body parts” check mark for the 
“is” comparison method.

I'm not saying that this shouldn't be easier :) For example, when using 
the `A` search MailMate should (to be intuitive) somehow also search the 
name which is generated for display.

No, I don't believe it is.

That “trick” should not trigger re-downloading emails, but it could 
certainly work better. In general, rebuilding should not be needed 
unless MailMate detects an issue itself. I'm afraid it's used far too 
often in an attempt to fix unrelated issues (not that this particular 
issue could not somehow have been related).
