Subject: Testsuite: find a group name if 'mail' is not available.
X-Git-Tag: exim-4_88_RC4~23
X-Git-Url: https://git.exim.org/exim.git/commitdiff_plain/1f187290089991b306083d9418a6cacb6a400f6b

Testsuite: find a group name if 'mail' is not available.

If the group 'mail' does not exist (as on some *BSD systems),
test 0001 fails. We now use a randomly choosen group, if necessary.

The group name isn't used for anything else than testing the config
file parser.
