Do you use Dovecot's deliver to save the mails to INBOX, or something
else? Do you have the Postfix mailbox opened while this happens? What if
you change "Max number of server connections to cache" to 1 in the
account settings -> server settings -> advanced?

I tried reproducing this for a while with Thunderbird, but couldn't get
these kind of errors.

Anyway, testing what happens with this patch would also help:
