Hi Sanjeev,
I don’t have the logs from failed sending.
I installed a local smtp relay without encryption which works fine. I tried to reproduce the error with the previous settings, but the error doesn’t occur anymore.
Thanks,
Freddy
Update: In the php error logs I find following entries: PHP Warning: stream_socket_enable_crypto(): SSL: The operation completed successfully.
