Ability mail server opsætning

Hej eksperter.
Mit problem med mailserveren er at jeg ikke kan modtage mails fra fx. hotmail, cybercity etc. eller jeg kan modtage 1 ca. hver 5-10 min. Hvis jeg derimod sender fra fx. wannafind til min mailserver kan jeg modtage konstant. Har i en fiks lille idé til hvad der er galt?

Her er min opsætning:
