Earlier I talked about generating random Subject lines for emails. I settled on something that looked like Subject: Your email (1024) . Those were fine, but got dull quickly. By switching the procmail rules to look like:
:0 fhw * ^Subject:[\ ]*$ |formail -i "Subject: RANDOM: $(fortune -n 65 -s | perl -pe 's/\s+/ /g')" :0 fhw * !^Subject: |formail -i "Subject: RANDOM: $(fortune -n 65 -s | perl -pe 's/\s+/ /g')"
I'm now able to get random subject lines with a little more meat to them. They come out looking like: RANDOM: The coast was clear. -- Lope de Vega
However, given that the default fortune data files only provide 3371 sayings that are 65 characters or under the Birthday_paradox will cause a subject collision a lot sooner than with the 2:superscript:15 possible subject lines I had before.
Update: It's been a few weeks since I've had this in place and my principle subject-less correspondent has noticed how eerily often the random subject lines match the topic of the email.
