That is not a Postfix Message-ID header. See below for examples

That is also not a Postfix message-ID header.
Postfix Message-ID headers have one of the following formats:
<20180329053241.c57e2332...@english-breakfast.cloud9.net>
20180329053241 is the UTC time in seconds in in YYYYMMDDHHMMSS
form, and C57E2332224 is a short Postfix queue ID (hexadecimal
string with 5 characters for the sub-second time in microseconds,
followed by the file inode number).
<40bxk51ky2zj...@spike.porcupine.org>
40BXk51Ky2zJrNr is a long Postfix queue ID (6 or more characters
for the UTC time in seconds, 4 characters for the sub-second
time in microseconds, the 'z', followed by the file inode
number.
