The answer to (3) directly is, "no"* - which is why SPF is so useful, since it doesn't require large (or any) changes to a user's clients (assuming you're not doing mailing list expansion via your MUA, which I believe some packages do). The SPF pages at pobox have all the details you could want, including pointers to various implementations. It's pretty simple and straightforward; furthermore, the license situation is positive. If the MARID stuff ends up encumbered with what RMS calls a non-free-software-compatible license then it's quite likely that it simply won't fly, regardless. SPF itself is in use right now, however. jan * if you're originating email from "offsite" (dialup lines etc.) then you may need to coordinate with your mail admin to ensure you're targeting the correct MSA. -- jan grant, ILRT, University of Bristol. http://www.ilrt.bris.ac.uk/ Tel +44(0)117 9287088 Fax +44 (0)117 9287112 http://ioctl.org/jan/ Donate a signature: http://ioctl.org/jan/sig-submit
