[CLUE-Talk] email filtering

[Michael Clark]

Depending on how dyndns handles their email, they probably store it for up
to three days (I think sendmail has a default for this??), which would
cover most, if not all, disconnects.

As for aliases, with sendmail I would edit my /etc/aliases (there are
examples in it) and run 'newaliases' as root.  That would activate the
changes. (I am currently running Mandrake 7.2, which uses postfix, and both
/etc/aliases and newaliases work identically to sendmail, fwiw).

I seem to remember another option, maybe a dotfile in your home directory?

Overall, I would say that Grant's fetchmail solution would be the easiest,
but you would have to rely on your dns/email provider to setup and maintain
your aliases ;-).

six of one, half dozen of the other
