Dovecot 2.3.17 can not start - too many parameters

[Michael Kliewe]

Hi,

I have heard rumors that this happens when you provide a CA bundle file 
which is big. If you just provide a single CA file it works. Something 
has changed there, maybe the developers have more details about this change.

King regards
Michael
