newmail is a simple script to generate random e-mail aliases from the command line for OpenSMTP on OpenBSD. I wrote this to avoid having to give out my real e-mail address to every place which requires registration.
whichmail lets you look up which e-mail you generated for a specific site/purpose.
To get a new e-mail address, you simply run newmail, with an optional argument identifying the site you associate with this address:
user@example.com$ newmail hub.darcs.net
pemovrypur@example.comAnd if you later forgot which one you had generated:
user@example.com$ whichmail hub.darcs.net
pemovrypur@example.comAfter running newmail, the following lines have been added to /etc/mail/aliases:
# f5cb7a763186dea37d3f98f7ce9bae6a9449587892acd69f89f88bcae71e694f
pemovrypur: userwhichmail to look up the addresses.user will receive e-mail sent to pemovrypur@example.com.apg1, for reasonable looking random addresses, available as a package as an OpenBSD package.rc and ssam from plan9port2 (also an OpenBSD package).Download and copy the above scripts to
/usr/local/bin/newmail and/usr/local/bin/whichmail.Edit the configuration variables at the top of the script. Remember to read through the source files to understand what they do. Then consider applying a few conveniences to your system configuration.
The following line in /etc/doas.conf enables users3 to run it:
permit nopass :users as root cmd newmailFor ease of use, I also added the following to /etc/skel/.profile and current users $HOME/.profile:
alias newmail='doas newmail'The scripts are written in rc (the shell of Plan9port). You can easily port them to any other shell your self. The newmail script itself is roughly ten lines.
