Rmail Problem

[Robert Thorpe]

I'm having some problems with Rmail and perhaps with Movemail.

I recently upgraded my computer.  I upgraded Emacs with it, and changed the 
distro I use.

Since I did that Rmail sometimes gets stuck with particular emails.  There are 
some that it can't remove from my inbox.  It refuses to proceed after that.  I 
then have to go to my webmail and delete the email from there.

Has anyone come across this problem before?

I'm using Emacs 26.3 and GNU Mailutils 3.9.  I only use the following 
configuration:

--8<---------------cut here---------------start------------->8---
(setq rmail-primary-inbox-list
      (cons (concat "pop://"
                    "email address"
                    "password" 
                    "@mymailserver.com")
            nil))
--8<---------------cut here---------------end--------------->8---

Some emails cause the problem every few days.  For the bad email I got
most recently it says the following in my messages buffer:

> Getting mail from the remote server...
> movemail: cannot append message 1: Malformed email address
> (No new mail has arrived)

There is nothing wrong with the email address that I can see, it's a
normal x@y.com address.  I have tried using both the pop protocol and the imaps 
protocol.  I've also tried using Emacs movemail which gives me the error 
"movemail: Usage: movemail [-p] inbox destfile".

Is this a movemail problem or an Emacs problem?
