hi,
I have some errors with a
517-Domain does not exist: arpmuseum.de
I see, that there is no A record for this domain? is this right?
That's fine, as long as the domain has MX records.
Ok, so if i put the domain with its ip into etc/esmtproutes, courier should be able to accept mail for it?
No, because your DNS resolution is not working, which is what causes this error.
And: what exactly is the header, that does courier choke on mails from this domain? is it "from:" ? Or is it the server, that delivers the mail? i donÂt understand, sorry...
It is the mail envelope sender address, which has nothing to do with any header (although in most cases the same address also appears in the From: header).
