[mew-int 2853] Re: How can I delete invalid messages safely?

[Will]

Hi vvoody,

If you sync the %[Gmail]/All mail folder by pressing s, the messages will
no longer appear as "invalid," and deleting or refiling them will then
be correctly applied to your messages on the gmail server.
Unfortunately, the sync can, of course, take a while if you have not
done it recently.

Best regards,
Will
