I am now unable to send emails to multiple email addresses. I've tried both addresses in the To: field and one in To: and the other in CC:. It just hangs in the sending mode, dialog box stays there showing sending. I can send emails to each recipient individually but not both at the same time?

Who is the mail provider?
Host is iPage. I was on with them yesterday, their webmail (same email addresses) works fine so it appears that it's a Thunderbird issue.
Another user had the same issue:

What are your server settings, and what is the antivirus app?
