Hello,
I told exim that it should authenticate itself to the smart host
by putting
hosts_require_auth = smtp.smarthost.dom
in the transport definition, because this will be required from
tomorrow on anyway. Exim tells me:
> ... defer (-42): authentication required but server did
> not advertise AUTH support
TLS is explicitly not required.
I have checked manually that AUTH=LOGIN is supported:
> $ telnet smtp.smarthost.dom 25
> ...
> ehlo
> 250-smtp.smarthost.dom Hi.
> 250-PIPELINING
> 250-AUTH=LOGIN
> 250 8BITMIME
> auth login
> 334 VXNlcm5hbWU6
> YmVudXR6ZXJuYW1l
> 334 UGFzc3dvcmQ6
> cGFzc3dvcnQ=
> 235 authentication successful
> quit
Debugging the delivery attempt with exim4 -d -M msg-id did
not enable me to find the cause of the problem -- this is what it says:

What could be the reason for exim saying the "server did not
advertise AUTH support" ??
Thanks & Regards,
