Trying to send or "reply all" to a group message generates this error message. "An error occurred while sending mail. The mail server responded: 5.2.0 3uaJ1x0020rJ4F001uaJvR internal error. Please check the message and try again."

I can send individual emails and reply to individual emails without a problem. Only get error when sending group message or "replying all" to a group message.

Rats. 5.2.0 is about the most vague and unhelpful error code you could imagine. Typically, it's explained as "Other or undefined mailbox status".

How big is your "group"? What mix of To:, Cc: and Bcc: is being used? Are they separate discrete addresses or is a Mailing List being used? (I guess this isn't a Mailing List, since "reply all" wouldn't apply).

Have you reported this to your email provider? The error message is, after all, issued by their server.
