Hello!

I'm trying to use DKIM on my FreeBSD 7.2 amd64 box with Exim 4.70 from
ports but all I get is that messages without DKIM signature rejected
with strange commentary: 550 Administrative prohibition

configure:

...

acl_smtp_dkim = acl_check_dkim

...

acl_check_dkim:

  defer         sender_domains  = gmail.com
                dkim_signers    = gmail.com
                dkim_status     = none:invalid:fail
                log_message     = message must have a valid DKIM signature
                message         = try again later


accept

for corp security, sorry):

Messages with valid DKIM signature processed ok. The mail server was running
for a long time (before upgrade) well and the mail recieved and processed
correct. All I done is binary upgrade from 4.69 to 4.70 and add configure
parameters above.

Eximstats shows that rejects in even more strange manner:

3 Rejected DKIM: <BA>^A
2 Rejected DKIM: x<E6>A

Am I missed something?
