SMTP issues?

[#1]

Suddenly I can't send messages from PlusNet POP account.

Before I start tinkering, are there current issues, or the settings altered?

Don't use it often but comes in handy sometimes.

  Sending of the message failed.
  The message could not be sent because connecting to Outgoing server (SMTP) relay.plus.net failed.
  The server may be unavailable or is refusing SMTP connections.
  Please verify that your Outgoing server (SMTP) settings are correct and try again.

Must be local to you, @IanSn . I had no problems at all.

Thanks John,

Hmm, I suspect Thunderbird... Might have been the recent update.

Dunno about that - mine is the current one.

Its odd, other accounts are working ok.

Other suspect might be installing the Bridge for ProtonMail. Though I have no idea what that might have done.

Doesn't matter much. Its down to how much can I be bothered to tinker with it! Rarely use it these days.
