Mbox errors with webmail

[ryan.overton]

About 2-3 times a week, I get a user who gets this error, or some variation of it.

ERROR: Could not complete request.

Query: COPY 176 "INBOX.Trash"

Reason Given: UID COPY failed: Can't append - not in valid mailbox format:

what causes this?

Probably a script failure or an invalid email, somehow. You'll either have to repair the problem or empty out the file. This is another good reason to migrate over to maildir as it does away with this type of issue completely.

how does one do this??

Run:

/scripts/convert2maildir

This will give you options to first backup existing mailboxes and then to perform the conversion process. Note that Neomail is removed, as it's no longer supports, and users of squirrelmail will have to signup to their imap folders again afterwards.

is there a way to convert just a single person for testing purposes?

No, it's all or nothing.

Yes, I've found one. Here's how I did it.

1. SSH as root
2. Execute:
/usr/local/cpanel/3rdparty/mb2md/mb2md -s /home/username/dir/to/inbox -d /home/username/dir/to/

I've tested this method with a server that has maildir installed, created a a test email address, copied inbox file (mbox format) into /home/username/dir/to/inbox then run #2 above. Then it created all email in /home/username/dir/to/cur.

Note: change /username/dir/to/ to your actual path.

Hope this helps.
