Unreachable adress

I tried to reach an adress and immediately I get this message back (without actualisizing):

Uw bericht heeft sommige of alle van de beoogde ontvangers niet bereikt.

De volgende geadresseerde(n) kan/kunnen niet worden bereikt:
[email protected]’ - 5.1.1 [email protected]… No such user [3565]

Is their anybody who recognizes this and knows a solution?

This is a message from your email server telling you that the address you are trying to send the message to does not exist.

The solution is to find an address that does exist.

Hello Gary,

Thnks for the reaction. But that is not the problem. For the e-mail adress is reachable when I send an e-mail from my Gmail-account. But when I try it from my Xs4All -account, then I get the message that the adress is not reachable.

I hope you know the course of that. It looks like a problem with the settings of eM Mail.

Wgr, Wetiek

The message is from your server. Best to ask them what that is about.
