Re: [mlmmj] Problems with spam filters

Thanks. I don't understand why your rspamd says black-sheep-research.com 
has no valid SPF.

Your "digs" show that it has an include for yorkshiremail.com, which in 
turn specifies both my own mail server (mx.yorkshiremail.com) and 
smpt2go.com which is the mail relay that I use for general mail sending.

Where is there an SPF problem?

I don't either understand why your rspamd doesn't like the DKIM 
signature added by the mail relay (smtp2go.com) if that is what it is 
complaining about.
