Subj : anyway the wind blows To : August Abolins From : Maurice Kinal Date : Mon Apr 12 2021 22:17:06 -={ 2021-04-12 22:17:06.607549879+00:00 }=- Hey August! AA> My system has both of these Perfect! That confirms that the address is indeed part of the dupe checking routine. AA> [1] == MID: 1:153/7001 8QIOgQad AA> [2] == MID: 1:153/7001.2989 8QIOgQad That is what I see here. Also there is no doubt they are completely different MSGs, from two different systems. Right? Also it appears from this angle that your idea for the random serial number is indeed compliant with fts-0009.001 despite objections anyone might have about the methodolgy. AA> Perhaps you need to keep the "address" part the same for a valid AA> test. This was a perfectly valid test. If you actually need to see if it will pick up on a duped MSGID we could try that as well. I'll follow up this reply of a totally new MSG with the "1:153/7001 8QIOgQad" address serial number. Don't touch that dial! Life is good, Maurice .... Wa þære þeode þe hæfð ælðeodigne cyng.
