'Cheap and cheerful' is to let Exim read that same file.

Another way might be even more useful:

Granted appropriate 'group' membership et al, Exim has a lookup type of
'dirsearch' that can be run against the tree the webpages live in.

or the shell-holder's /home dirtree, or .... whatever.

If one or more 'user@???' be placed as subdirs or filenames at a
predictable path Exim can use the return from THAT to vet the needfuls.

Also useful for deciding whether to accept/reject for Ecartis closed-lists
before calling Ecartis to life at all. That allows turning OFF all Ecartis
bounces to anyone NOT a list member/admin, etc, thus preventing deliberate
non-member posts to a closed-list being used for backscatter propagation.

Which the bastids DO try to do ...

HTH,
