EDIT: I did get a little further but all posts on my search say permissions are wrong or regenerate key but I fixed that to be 644 as well as owned by DKIM AND I keep regenerating the key but it is not helping. My latest error now is this
Apr 21 21:19:12 Sniffy opendkim: BB5BF3AA66: dkim_eom(): resource unavailable: d2i_PrivateKey_bio() failed Apr 21 21:19:12 Sniffy postfix/cleanup: BB5BF3AA66: milter-reject: END-OF-MESSAGE from localhost[127.0.0.1]: 4.7.0 resource unavailable; from=<firstname.lastname@example.org> to=<email@example.com> proto=SMTP helo=<abcs.com>
I am looking for a way to simply debug this(don't necessarily need the answer but a way to get logs from opendkim would be good).
If I stop opendkim, I see postfix log connection refused which is good. but when I send mail with opendkim started, I see no logs whatsoever. I even add the "LogWhy Yes" line to my opendkim.conf file as well and still see no logs there.
Since I see opendkim running under user opendkim, I changed the owner of /etc/opendkim/* and /etc/opendkim and /etc/opendkim.conf all to opendkim user.
I am running on ubuntu. My opendkim.conf file is
# Log to syslog Syslog yes # Required to use local socket with MTAs that access the socket as a non- # privileged user (e.g. Postfix) UMask 002 # Sign for example.com with key in /etc/mail/dkim.key using # selector '2007' (e.g. 2007._domainkey.example.com) #Domain example.com Domain sniffyapp.com #KeyFile /etc/mail/dkim.key KeyFile /etc/opendkim/keys/sniffyapp.com/default.private #Selector 2007 Selector default # Commonly-used options; the commented-out versions show the defaults. #Canonicalization simple Mode sv #SubDomains no #ADSPDiscard no Socket inet:8891:localhost ExternalIgnoreList refile:/etc/opendkim/TrustedHosts InternalHosts refile:/etc/opendkim/TrustedHosts LogWhy Yes
I of course have these lines added to main.cf in postfix
smtpd_milters = inet:127.0.0.1:8891 non_smtpd_milters = $smtpd_milters milter_default_action = accept
