[Exim] verify = header_syntax

Hi all.

During processing of an ACL at rcpt time, I have
verify = header_syntax

Quick question.

if this fails, what variable can i refer to that tells me what caused the
check to fail without looking in the log-file?

Currently, I think the answer in 'none', but I'd like it confirmed.
If this is the case, could I add it to the wish-list? It is, I feel, a little
pointless if I deny mail based on the presence of syntax errors in the
message, if I cannot report what the error was...

TVM.

Phil.
