Subj : what is this? To : all From : mark lewis Date : Mon Sep 02 2013 21:26:13 what does the last sequence of characters in the following PIDs signify? PID: ALLFIX+ 6.00.18 EFF59863 PID: ALLFIX/2+ 6.00.18 A397509A is it supposed to be a MSGID serial number or is it some kind of registration number? the reason i ask is because i'm seeing some allfix v6.0 announcements in my dupes area... none of them have MSGIDs... however, my allfix 5.13 does generate proper MSGIDs and it also has similar numbers to the above on the PID line... thanks for any help with this! )\/(ark * Origin: (1:3634/12) SEEN-BY: 229/426 103/705 218/720 102/401 103/1 218/501 215 840 301/1 218/860 SEEN-BY: 218/880 214/22 218/900 870 930 601 124/5016 218/700 1 10/1 218/0 10/0 .
