I can at least point you in the right direction. Here is the most 
straightforward way to get something like that:

	defaults write com.freron.MailMate MmFilenameFormatString -string 
'${#date} ${subject} [${from.name:${from.address}}].eml'
	-> 2014-12-16 14;32;50 +0100 [MlMt] MmFilenameFormatString question 
[thfl at me.com]-1.eml

The problem with `;` is because `:` cannot be part of a filename. Note 
that the name of the sender is used if it exists, but it didn't for your 
email.

Slightly better perhaps:

	'${#date.formatted} ${subject} [${from.name:${from.address}}].eml'
	-> 16 Dec 2014 14;32 [MlMt] MmFilenameFormatString question 
[thfl at me.com].eml

Using a regular expression substitution, you can do something like this:

	'${#date/://g} ${subject} [${from.name:${from.address}}].eml'
	-> 2014-12-16 143250 +0100 [MlMt] MmFilenameFormatString question 
[thfl at me.com]

And it gets a bit more hairy to get somthing closer to what you wanted:

	'${#date/(\S*) (\d\d):(\d\d).*/$1T$2$3/} ${subject} 
[${from.name:${from.address}}].eml'
	-> 2014-12-16T1432 [MlMt] MmFilenameFormatString question 
[thfl at me.com].eml

I hope this helps and thanks for trying out MailMate.
