Subject: Testsuite: tidy generation and sorting of exim -bp output
X-Git-Tag: exim-4_89_RC3~8

Testsuite: tidy generation and sorting of exim -bp output

The root cause is, that exim -bp doesn't always return the message
ids in the order they were created, but sorted. The 2nd
part of the message id (PID) can be random on *BSD.
