Given the following procmail recipe:
:0:
* ^Subject:.*viagra.*
* ^From:.*viagra.*
/dev/null
Procmail would only delete emails that were both from viagra, and had viagra in the subject. Is it possible to apply the filter if either of the matches are true?
The solution should preferably not make use of the regular expression (regex1|regex2) operation, but if that is the only solution, then please say so.
