Someone recently posted on 'gab' about getting spam on their RTC email
account. It got me thinking about creating a simple whitelist for
separating friends from foes. Noramlly one would use something like
procmail but as there currently isn't such a tool on RTC I took a stab
at writing one, in AWK naturally:
$ head ~zilog/public_bin/onlyfriends
#!/usr/bin/awk -f
# -----------------------------------------------------
# onlyfriends :: a simple AWK-based MDA; email from
# non-friends go to ~/Maildir/Spam/
# -----------------------------------------------------
# how to use:
# 1) create ~/Maildir/Spam/{cur,new,tmp}:
# $ mkdir -p ~/Maildir/Spam/{cur,new,tmp}
# $ chmod 700 ~/Maildir/Spam/{cur,new,tmp}
# $ chmod 755 ~/Maildir/Spam
#
# 2) create or edit ~/.forward file like so:
# $ echo '|/home/zilog/public_bin/onlyfriends' > ~/.forward
# $ chmod 640 ~/.forward
#
# 3) add address & domain fragments of friends to ~/.friends:
# $ echo '@rawtext.club' > ~/.friends
# $ echo 'membership@sdf.org' >> ~/.friends
# $ echo 'sweetiepie@' >> ~/.friends
# $ chmod 640 ~/.friends
#
Lines of code: 61
I've testing it a bit with my various email account and it appears to
work as intended. I *think* it ought to work for others on RTC as well
without further tweaks but that remains to be seen; perhaps I can get
some testers..
Prior to this exercise I hadn't really looked into how Maildir-style
email messages were created and processed; took a bit of trial and
error to get my MUA (s-nail) to stop complaining.
