Question

Are there any handy general items you put in your .procmailrc file?

Answer 1

Many mailers prefix a mail’s subject with ‘Re: ‘ when replying, if that prefix isn’t already there. German Outlook instead prefixes with ‘AW: ‘ (for ‘AntWort’) if that prefix isn’t already there. Unfortunately, these two behaviours clash, resulting in mail subjects like ‘Re: AW: Re: AW: Re: AW: Re: AW: Lunch’. So I now have:

:0f * ^Subject: (Antwort|AW): |sed -r -e '1,/^$/s/^(Subject: )(((Antwort: )|(Re: )|(AW: ))+)(.*)/\1Re: \7\nX-Orig-Subject: \2\7/' 

Which curtails these (and an ‘Antwort: ‘ prefix that I’ve evidently also been bothered by at some point) down to a single ‘Re: ‘.
