E-mail error, snap 't niet..

[Verwijderd]

Ik heb een kantoor met 10 computers. Daar draait 1 internetserver en 9 clients. Die 9 clients hebben email laten we zeggen [e-mail] als die clients naar elkaar mailen krijgen ze de volgende foutmelding.... in en uit mailen wil wel lukken naar andere domains. Waar kan dit mee te maken hebben?

Dit is een foutmelding weet niet precies waar 't aan ligt.

[André]

Reason: Remote SMTP server has rejected address
Diagnostic code: smtp;550 <[e-mail]>, Recipient unknown

Bestaan die mailadressen wel? Waar staan de popboxen?

sommige SMTP servers checken of de afzender wel geldig is. Het lijkt erop dat je SMTP server niet van buiten je lokale netwerk is te benaderen.... (poort 25 niet gemapt naar de server ofzo)
