[Alpine-info] "syntax error in sequence"

[Paul]

Hi -

Once every week or two, when I send a reply (via a remote SMTP server), 
Alpine 2.25 tells me "Syntax error in sequence" after the send finishes.

I've been ignoring the messages, but lately it seems that those messages 
never reach the recipient! That's a problem.

The message is successfully FCCed to the sent-mail box, but the 
"Answered" flag isn't set (my inbox is a local Maildir).

How can I track this down?

thanks,
 	Paul
