Unfortunately, this didn't fix the problem.  I get the paniclog entry
even using this ACL:

"""
acl_check_dkim:
   warn
     !dkim_status   = invalid
   accept
     dkim_status    = none
   accept
     dkim_status    = none
   accept
     dkim_status    = pass : invalid
   accept
     dkim_status    = fail
   accept
"""

Any further suggestions?  The only other mentions of DKIM in my
configuration are:

acl_smtp_dkim = acl_check_dkim
KNOWN_DKIM_SIGNERS = paypal.com : gmail.com : ebay.com : yahoo.com : fastmail.fm
dkim_verify_signers = $dkim_signers : KNOWN_DKIM_SIGNERS

Thanks,
Tony


Been quite a distance from my kbd for a few days, but I have nothing further on the whyso. You've posted the entire acl set, folk far more expert than I have parsed that - which is not the same thing as saying it is w/o flaw. A fix will probably show up soon.

*I* am still puzzled on a peripheral issue - why the 'panic' log is the destination AND NOT main or reject log.

Wot I expect in PANIC is something that either prevented Exim starting (can't get the IP or port), prevents doing the basic job on ALL or MOST traffic, (bad perms, missing files, certs, scanner socket or IP, DB connection not working ... or something that has already knocked it down.

Given that, inability to GEN a DKIM sig might qualify as a 'panic' but inability to vet one presented is no different that any other 'credentials' fail.

Eg: serious w/r that message, problematic for that sender, but not of the sort of fail that knocks Exim off its perch otherwise - as in still OK and continuing to pass DKIM'less messages in general and DKIM sigs w/o the specific glitches in particular.

IMHO, that ... classing it as a 'panic' - needs looked at, regardless of what triggered it [1].

[1] An illegal attempt to write to the fs is 'serious', but should be simply prevented at that point, not attempted, then seen as a panic when it fails.
