Strange email behavior catch-all / main email account

[fwpeter]

We encounter strange behavior of one user in DA (1.31.4). The account has a number of pop3 mailboxes as well some forwarders. One pop3 mailbox has been configured to be the catch-all account. But this seems to fail. A lot of email is been delivered to the default email account (username, without the @domain.tld). Configuration:

Email accounts configured in webinterface (Debian Exim, last version without Dovecot):
username (not configured to receive any email)
[email protected] (configured to receive catch-all email)

Spamassassin enabled.

Most email not tagged as spam is delivered in the catch-all account. However, most spam messages (and a number of non-spam email messages) are delivered in the main email account ([email protected]).

How can this occur? All other user users/accounts seem to work properly.

John, would you please take a look at this issue? Thank you!

It seems to occur due to a filter rule. Blocking all e-mail containing a word will send the mail to the spam box of the main e-mail account. I'm testing this at the moment. This seems to be not the expected behavior. Don't we want these 'spam' messages to the catch-all spam folder instead of the default main account?
