[imapfilter-devel] interest in filter mailing lists on unknown names

[Tobias Eigen]

Dear Lefteris and Gautam, 

Many thanks for this response. I'll wait until the next stable version of
imapfilter is released then try these out. 

Do either of these examples check that the message ID is unique? 

Best wishes, 

Tobias
