SA-exim 4.0 crashes on discard

Hello,

I noticed on our mailhubs that some mail was being delivered to userids
beginning with a hyphen. We have no such userids so I modified exim to
discard these. This was before installing sa-exim 4.0 - and it worked
okay. I have now installed sa-exim onto our second mailhub and in
testing that mail sent to '[email protected]' was discarded/rejected I got
the following error in the main and reject logs, there is no panic log:

=============================================================

In our configure file for the RCPT ACL we 'discard' invalid local parts.
If I change this to 'drop' then it works okay - no crash.



Regards,

John.
