Hi,

I did try to search in the forum but can't find any similar error, the MTA can't be started due to opendkim error, I sure the ldap is working fine and I can get those info DKIMDomain, DKIMKey, DKIMSelector and DKIMIdentity when I use ldapsearch

ldapsearch -h xxx.xxx.xxx.xxx -p 389 -b "dc=domain,dc=com" -x -a never -D "uid=zmpostfix,cn=appaccts,cn=zimbra" -W

I also don't think this is caused by DNS problem and there is no much information show in the zimbra.log as well, I'd be grateful if anyone can give an idea the possibility cause or provide me a command how to start debug mode in opendkim.

Thanks.
