You might be right, but I also think that if Dovecot needs a fix, it 
would be also a good thing to provide an updated online version 
including the fix instead of an unfixed version @ dovecot.org that

The simple fix has been communicated over this list.

Unfortunately his fix is not available @ dovecot.org which gives the 
impression that the current non-SSL functionallity can only be fixed 
through a mailing list populated by incrowd.
