Rose, I guess I should respond. There are several POP protocols. As to which one is the official one, that's a good question. The original POP was done at USC/ISI. The people working on MH liked this quite a bit but weren't able to quite implement it, so I did an alternate service/protocol specification and put that in MH. Shortly thereafter, USC/ISI came out with POP2, which pretty much fixed all the problems in the original POP. For reasons not worth going into, MH's POP and ISI's POP2 never merged, so future POP work in MH used MH's POP. This future work included support for remote BBoards (which you can also get with NNTP, I think) and support for Stanford's version of MH for the PC. About 10 months ago, the parties involved were supposed to get together and solve this problem (multiple versions), but we never got around to it. Hence the current situation. The question as to which version is official and which version(s) are useful, being widely implemented, is problematic. The original POP is history. That leaves POP2 and MH's POP. /mtr
