Oh, I meant that the redirect router should pull it from the alias file. :)

I'd like to have it compatible with all the other entries in the alias
file. For an entry like

foo:    fl@???


your suggestion gives the error
R=test_filter defer (-1): "fl@???" is not an absolute path

Also, and that would be a bigger problem, it is syntactically identical
to the

user:        /path/to/mailbox


syntax for direct delivery into a mailbox, so that would break too.

Something like:

user:        ":include:/path/to/filterfile" 


would be perfect, but the manual explicitly says that this doesn't
work for filter files. What's the reason for this?

Kind regards,

Florian
