Just to add my recent experience to this useful thread. Yahoo seem to be
the toughest, I currently have an old domain with correct PTR records
and SPF set up which simply gets dropped by Yahoo's servers. I get a
warning regarding delayed delivery then a day or so later a failed
delivery error.
The domains that are successfully getting through to Yahoo have DKIM set
up too (although I don't think this always needs to be the case).
I have just filled out this form which I am told can help:
http://help.yahoo.com/l/us/yahoo/mail/postmaster/bulkv2.html;_ylt=An8jLP5eP8VPdGZvTxFMD6eiNCV4?from_url=&last_url=
we'll see...
