Thunderbird fails to send emails on the first request (per account)

[Frederic Muller]

Hi!

So now that I have solved my screen problem I am having a weird annoying
problem with Thunderbird which is failing (time out error, but very fast
response) to send email on the first "send click" on every account.
After that everything works as long as I don't restart TB.

Any idea what this could be and how to look into it?

Thank you.

Fred
