Log:
Exim crashed for a huge SMTP error response; increasing big_buffer_size
for Exiscan made this go away, but I've now also made the code more
robust.

51. Small patch to Sieve code - explicitly set From: when generating an
autoreply.

+52. Exim crashed if a remote delivery caused a very long error message to be
+ recorded - for instance if somebody sent an entire SpamAssassin report back
+ as a large number of 550 error lines. This bug was coincidentally fixed by
+ increasing the size of one of Exim's internal buffers (big_buffer) that
+ happened as part of the Exiscan merge. However, to be on the safe side, I
+ have made the code more robust (and fixed the comments that describe what
+ is going on).
