Der er ikke noget i din mail der har med URL'er at gøre. Det du kalder
en URL hedder altså "domæne" eller "hostnavn".

Der er helller ikke noget i vejen at et domæne eller hostnavn har
flere IP-numre. www.l.google.com har for eksempel 2. Det er helt
normalt.

Problemet er opsætningen af reverse-DNS, det vil sige mapningen fra
IP-numre til domæner. Her peger 148.122.180.27 på
shipshore.imnc.eik.com uden at shipshore.inmc.eik.com peger på
148.122.180.27. Dette er et kraftigt indicium for at rDNS er falsk og
at der er nogle der uretmæssigt prøver at udgive sig for at være
eik.com.

Prøv at sætte den til at acceptere mail fra 148.122.180.27 istedet.
