Thunderbird abruptly stopped sending mail. No error message shown. The mail just sits there.

Tried sending from another account. Same. The same server settings work fine on another computer from my home.

I read the knowledge base and it recommended checking add-ons. But I cannot find any under Tools or anywhere else.

Server type: IMAP Mail server: mail.pobox.com Port 993 SSL/TLS Normal password

Outgoing server: smtp.pobox.com Port: 465 SSL/TLS Normal password
