Spammer lennék?

Általában tudok levelet küldeni gmail által managelt domain-ű emailcímekre is, de vannak kivételek (lásd lejjebb).

Valaki fel tudna világosítani, hogy ez a levelem miért nem ért célba?
(Vastagon kiemeltem amit végképp nem értek. A csillagokat is én helyeztem el a lenti töredékben.)
