Subj : anyway the wind blows To : August Abolins From : Maurice Kinal Date : Mon Apr 12 2021 20:52:02 Hey August! Here is an official test of duplicate MSGID serial numbers from two different addresses to see if it shows up as a false dupe. Note that I am using the 8 character serial number which is restricted to [a-z][A-Z][0-9] aka [:alnum:] regex. So far it appears to be working as I've already seen it converted to a REPLY kludge in MSGs from a number of different sources so now all that needs to be confirmed is the dupe checking. For the record I still believe the 32-bit hex unixtime to be the better option given that it actually represents something useful beyond just dupe checking. Life is good, Maurice .... Don't cry for me I have vi. --- GNU bash, version 5.1.4(1)-release (x86_64-motorshed-linux-gnu) * Origin: Little Mikey's Satellite - Ladysmith BC, Canada (1:153/7001.2989) .
