Betreff:        [Assp-user] SSL didn't work



Hello Thomas,
 
We work ASSP for long time, about two years,  problemlos. Version 
2.6.1.build 19007.
Since Friday 8.3.2019, access by port 587 freezes time to time. Only assp 
restart helps.

assp.cfg:
listenPort:=25
smtpDestination:=[::1]:125
smtpDestinationRT:=
smtpLocalIPAddress:=
listenPortSSL:=465
smtpDestinationSSL:=127.0.0.1:565
listenPort2:=587
smtpAuthServer:=SSL:127.0.0.1:465
 
Our log:
