Subject: Correctly wait for the MTA to finish before exiting.
X-Git-Url: https://projects.mako.cc/source/attachcheck/commitdiff_plain/e1c3042eba5989f7db537ceda2766e08c15f9b59?hp=e1c3042eba5989f7db537ceda2766e08c15f9b59

Correctly wait for the MTA to finish before exiting.

And use the MTA's exit code as our own (so that the various
possible error states are correctly reported to the MUA).
