Since Monday 8th June 2020 I am having trouble sending emails from thunderbird pop3. It just sits there and finally come up with the following message ----"Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.ntlworld.com timed out. Try again."
This is happening on Thunderbird both on Windows 10 and Linux. No settings have changed and I have checked all the settings as stated by Virgin.
I think Virgin were doing something to email on Sunday night as I was getting a message that they were doing maintenance.
Thanks for the response. I have now changed server setting from pop3.ntlworld.com to pop3.virginmedia.com and outgoing server from smtp.ntlworld.com to smtp.virginmedia.com
After this I did have to enter my password again and could receive emails ok but sending still seems to be very intermittent and only seems to work after I edit outgoing server but do not change anything and then click ok. Maybe its to do with the sticky you mention. Again everything was fine until Monday 8th and that was using the old ntlworld settings
