[exim] Taint mismatch in exim 4.93.0.4

Hi,

after upgrading to exim 4.93.0.4 it complains about

    2020-02-24 11:08:47 1j6AfP-002SAT-9R Taint mismatch, string_vformat: spam 404

in SMTP DATA ACL. The config looks like this:

    deny     message     = This message was classified as SPAM
             spam        = nobody/defer_ok

The message is temporarily rejected. Any idea?

Regards,
Heiko
