E-mail forwarder fails "retry timeout exceeded"

Hi,

I've got quite a unique e-mail situation. Two domainnames run on the same server: domain1.com and domain2.com.

For domain1.com I've created e-mail forwarders who point to an existing e-mailaddress on domain2.com which is using Google Apps.

Domain1 uses local delivery for MX (to forward the e-mails) while domain2 doesn't use local MX records because it's running Google Apps.

When I send e-mails to domain1.com, it keeps failing. I've tried to add domain1.com as whitelist domain in the exim conf, but that didn't work.

Any suggestions?

Thanks!

What error is in the logs. What error is displayed as a bounce back.

Any idea how I can solve this?

Once it's returned it's too late to see why. Send another email to the same address. After it fails the first few times check the exim mainlog, or even the queue, to see the underlying failure cause.
