Big problem today, impossible to send/receive email

[JL]

Hi, all of a sudden, I cannot send nor receive in Outlook ANY email from my 2
SMTP and IMAP servers (gmail, fastmail). I use WinXP, OL XP.

I get those error messages: gmail: your outgoing server doesn't support
SSL-secured connections

fastmail : could not fetch new headers in the folder Inbox / (null) for
account fastmail. Unable to connect to the server...

I didn't change anything in my email settings. I made some changes in my
firewall but if I disable it, I get the same result.

It seems my vfemail works normally.

Could you tell me what is wrong, please?

Thanks a lot.
