Hello,
We may have something wrong somewhere, but can't find it.
We have a domain (say domainA.com), in which we have the users (configured as local in EA)
We have a subdomain (mail.domainA.com) configured as remote/remote host in EA pointing to domainA.com
Everything works fine (external receive, external delivery).
But for an obscure reason, when userOne@domainA.com sends an email to userTwo@domainA.com, it doesn't work, returning the following error : 501 local user must be authenticated at first.
What are we missing ?
TIA
Christian
