I used to have a little more complex regex in use, however, I've seen spam come from those domains as well. I like to assume that anyone sending mail from a canonical or ubuntu email address will be in good faith. However, I realize these can be spoofed too. I have more than just these in the list but those are the two that will concern other users. You could easily append additional domains the exact same way. When I started off with list management, I was using the default settings. I think they were pretty close to defaults. I added a line to "reject_these_nonmembers" which basically amounted to , if the space between user and .com/.edu/etc. part of the email was beyond a certain length it was held. I don't remember the exact regex, but I did this because most spammers tend to have a very long domain name. This wasn't good enough which is why I switched, but that alone helped a lot. > - -- Michael Lustfield Kalliki Software, SD LoCo Network and Systems Administrator -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) iEYEARECAAYFAkoqkEoACgkQ3y7Nst6YLGUP+QCgspBSYfl2S6C9Qt7TQLfiZ5Cz LQUAoIdqgX185bXMMmb8npYK2Gv9p3K7 =SNaD -----END PGP SIGNATURE----- -- loco-contacts mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/loco-contacts
