Is this Microsoft's System.Net.Mail or Mono's System.Net.Mail or both?

If you initialize GMime with g_mime_init 
(GMIME_ENABLE_RFC2047_WORKAROUNDS); GMime 2.4.x and 2.5.x should both 
handle the test case you provided. I just tested 2.5.8 and 2.4.25 and it 
works fine. 2.4.14 may be too old, I'm not sure.

The problem is that periods must be encoded if they are inside an 
encoded-word token and in your example, that is not the case. The 
software that produced the encoding has a bug.

Hope that helps,

Jeff
