[arch-dev-public] request: remove mailx from Core

Hi! logrotate-3.7.5-1 no longer depends on mailx (FS#6911) and no other package in Core does. FS#4812 says that mailx should depend on smtp-forwarder as /usr/bin/mail calls /usr/sbin/sendmail. Doing this will bring an interesting situation when a package in Core depends on a virtual package provided by many of packages in Extra. I suggest we remove mailx from Core completely (after logrotate-3.7.5-1 will be signed off), because it's not required there anyway. -- Roman Kyrylych (Роман Кирилич)
