MailScanner Text File Creation

[Stephen Conway]

Hello:

I do know perl and am writing the functions, but I am looking now at the
Custom Function , the only problem I have, is that the Custom Function must
be called from within the config file, and not from within a ruleset.  If I
use custom functions, the one for the non SPAM actions is easy enough, but I
will also need to do all archiving things / criteria from a custom function
as well.  Or is it possible to do a custom action from within a ruleset?  If
not, this would be a great future additon to provide the option to run
custom actions from within a ruleset, in a similar fashion to the way you
have already from within the config file.

Thanks,

Steve

Yes, it can be done. It would need a Custom Function attached to the
Archive Mail option, and one attached to the non-spam actions option. This
could ask if the particular header was defined, and produce a different
result in this case, compared to the normal response.

But you will need some knowledge of perl to be able to write this.
