[exim] option -MCd

Hello,

my exim-4.94 has problems. Message coming in via TCP doesn't get delivered.
The debug output is

264380 SMTP>> 221 siffux.fritz.box closing connection
264380 LOG: smtp_connection MAIN
264380 SMTP connection from (siffux.fritz.box) [::1] closed by QUIT

264363 child 264380 ended: status=0x0
264363 normal exit, 0
264363 0 SMTP accept processes now running

The problem is new, exim-4.93 works perfect.


Greetings, Frank
