When I look at the mail log I see entries like this
The configuration of opendkim is outside the scope of this list. As an example however, the server that sends this list's mail is mail.python.org, but it dkim signs from the python.org domain. In any case, the public key text record needs to be in DNS at sss._domainkey.ddd where sss is the selector and ddd is the domain in the DKIM signature. > Apr 19 07:49:42 hostname opendkim[1738]: 091CE1205AE: s=ppsdkim d=ucsf.edu > SSL error:04091068:rsa routines:INT_RSA_VERIFY:bad signature > > Apr 24 09:25:31 hostname opendkim[1738]: 3B7CA120431: s=mail > d=domainname.tld SSL error:04091068:rsa routines:INT_RSA_VERIFY:bad > signature > > Lastly, I'm confused by the term in the Mailman interface of ' host_name' > where it says > ...> Is the host-name literal for my server? Right now I have it set at > lists.domainname.tld. Is that incorrect? Mailman's host_name setting should be the domain to wich you send list mail. If the list's posting address is listn...@lists.domainname.tld, then lists.domainname.tld is correct, but if you post to listn...@domainname.tld, then host_name should be domainname.tld. > Finally, my mailing list distribution success is mixed.

And without information from the failed recipients ISPs as to why they discarded or spam filtered the mail, you won't know why, unless of course they outright bounce it in which case the reason should be in the bounce DSNs. -- Mark Sapiro <m...@msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
