libemail-filter-perl 1.035-1 (s390x binary) in ubuntu oracular

 Email::Filter is another module produced by the "Perl Email Project",
 a reaction against the complexity and increasing bugginess of the
 "Mail::*" modules. It replaces Mail::Audit, and allows you to write
 programs describing how your mail should be filtered.

 This module is not actively developed upstream anymore.
 Cf. Email::Filter.3pm.
