I have a rather annoying problem with ISPconfig 3. I'm currently running version 18.104.22.168p8, but the problem has always been there. Some mailboxes will always be deleted whenever a change is made to the account. It only happens for some accounts, but it seems to happen every time such an account is changed. I just got a support ticket from a client, that needed a password reset for a mailbox. I changed the password, it worked instantly, but a couple of minutes later, the account was deleted from /var/vmail/, but not from the database. Luckily I took a backup before the password reset, because this has happened to me several times with another account. With the other account it was a change of spamfilter settings, that provoked deletion. At that time I tried several things to prevent the account from being deleted (for instance I deleted it from database and created it manually again and backed up the files). But nothing worked so I eventually gave up and decided to make a backup every time I made a change. Can someone help me debug this problem. It's rather annoying to have to go through the extra step of taking a backup just for a trivial password reset.
