> your precious SPF slots
'slots'? You just add another `include` section - there is no number of slots. And even if there was, you don't want email being addressed from a fake looking domain.
The benefits of having a dedicated domain are far and few between. Particularly the reasons listed here are poor ones. It is far more beneficial to use a single trusted domain than to create a confusing mix of domains which look possibly fake.
- kl4m 12y agoRFC 4408 Section 10.1 says there is a limit of 10 DNS lookups for SPF entries. SPF validation tools will warn if an entry goes over that limit. http://www.ietf.org/rfc/rfc4408.txt http://www.ietf.org/rfc/rfc4408.txt
