The files in the tmp directory were not showing up in my mailbox.

I resolved both using the following technique. Anyone can see the solution in the archives if they run into the same situation.

Create a temporary mailbox (.INBOX.tmp_email).

For each mailbox that had an issue, Items 1) and 2) below) Move in Linux (mv command) all suspect files from 1) and 2) below into the .INBOX.tmp_email/cur directory.

Use mail client to move the messages from tmp_email mailbox to the <original mailbox>.

Verify in Linux that the files are correctly formatted in the <original mailbox>/cur directory

Everything is running smoothly now.

Not sure if this actually has any impact, do you get an error?

I had to restore many thousands of dovecot emails from a crashed Mac Server to a new Ubuntu server. After completing I am noticing a few things that may be okay or may need to be fixed.

1. a couple of mailboxes have a lot (one has 102462) emails in the tmp directory. The files do not have the standard Mairdir++ filename format. An example: 1581262582.M397740P72267.mini.mmpcrofton.com (http://1581262582.m397740p72267.mini.mmpcrofton.com/) (missing the stuff at the end,,S=,W=:2,S)

2. I see files in the cur directory that do not have the Maildir++ format. An example: 1601287326.V810Ie80087M240104.mmp-mail.mmpcrofton.com (http://1601287326.v810ie80087m240104.mmp-mail.mmpcrofton.com/):2,S. (do not have the,S=,W= values and the second value, V810Ie80087M240104, is longer that the other file names)

How do I get the emails in (1) out of tmp?

Do I need to convert the emails in (2)?
