SMTP Issue since upgrade to Version 8

1

I cannot send SMTP messages anymore since the upgrade to version 8. The mail server is hosted by df.eu. I tried the SSL/TSL settings and the non encrypted ones; same result. I use Avast, however, even with the mail shields all turned off, there is no difference. Below is the log entry when trying to send an email. No idea what I need to do to get this going again. Thanks.

Additionally, using the G-Mail client on my mobile phone, sending of SMTP emails works just fine. Exactly the same server settings.

I just tried to use Port 587 which is not listed as a port for SSL connection by the provider. It worked. :grinning:

Problem solved.
