Hello,<br>
<br>
Virgin Media uses SSL/TLS on port 465 for email submission via SMTP:<br>
<br>
$ dig _submission._<a href="http://tcp.virginmedia.com">tcp.virginmedia.com</a> -t SRV +short<br>
0 1 465 <a href="http://smtp.virginmedia.com">smtp.virginmedia.com</a>.<br>
<br>

Claws Mail supports SRV records for autoconfiguration. Unfortunately, it always assumes that STARTTLS (=explicit SSL/TLS) is used for SMTP. But in this case I need implicit SSL/TLS on port 465.<br>
<br>
I would like to suggest that the autoconfig wizard in Claws Mail tests if STARTTLS works for SMTP. If it doesn't, it should try implicit SSL/TLS.<br>
<br>
If this is not possible to implement, I suggest that implicit SSL/TLS is always used for port 465. It is very unlikely that someone would be running STARTTLS on port 465. Ports 25 and 587 are commonly used for STARTTLS.<br>
