I just wanted to report an oddity with Dbmail 3.1.3 and mailboxes containing the "&" character which themselves contained mailboxes.

I don't know if this was a one off, or something to do with dbmail 3.1.3

Just to try and make this clear a user had a mailbox structure like this (as viewed in Thunderbird):

Admin
Admin\External & Internal
Admin\External & Internal\Surname,Forename 1
Admin\External & Internal\Surname,Forename 2
.....etc
Admin\External & Internal\Surname,Forename 20


In the dbmail_mailboxes table the folders with the & character were shown as containing "&-"

Admin\External &- Internal\Surname,Forename 1

But not every folder with a & symbol had the extra - in place.

Now we have been running 3.1.3 since Monday (now Friday) and although these mailboxes had been used during the week (they contained e-mail messages from Thursday for instance suddenly this morning there was the situation where whichever mailbox was opened showed the wrong messages internally. So Surname,Forename 2 as well as Surname,Forename 4 might contain the messages "really" from Surname,Forename 1. There were a couple of folders whose messages were seemingly duplicated in all the rest.

This behaviour was observed in both Thunderbird and Roundcube; and also in further different mailbox trees which contained the ampersand symbol and subfolders thereunder (in one example where each subfolder was a year each folder showed the contents of the first/earliest folder).

The only things which happened were where odd where:

a) I ran dbmail-util -ctubdsv -y yesterday afternoon
b) the cron job put in place for 3.0.2 to restart dbmail-imapd (using the FreeBSD script dbmail-imapd restart) hung at 0300 when running and had to be killed this morning.

Clearly I was worried there was major corruption going on, but then thought it might be the ampersand and just renamed the offending mailboxes... which resolved the situation and the normal contents of the mailbox was shown in both Thunderbird and Roundcube.
