* 1.0 SPF_SOFTFAIL SPF: sender does not match SPF record (softfail)

This is a problem that came-up before, and was deemed fixed(v 7.x), though I personally cannot confirm whether that was the case.
That said, I noticed an ongoing issue with Cloudron/Haraka mail, in-that it is not acknowledging SPF record entries, and thus detrimental to spam score;
