Delivery is delayed in exchange server 2007

Question

I have exchange server 2007 and everything is fine until I try to send attached file or simple email to another exchange server i got this message "delivery is delayed to these recipient" but if I try to send the same email from Hotmail or yahoo the email received. Can any one help me.

Answer 1

First question - is this a delay, or an error? As in: Does the email finally go through after some time, or does it delay for some time, then fail?

Basically - obviously not everything is fine (your statement contracdicts). I would check SMTP protocols. SOmehow hotmail, / yahoo dont like your email. Can have a OTON of reasons, but this needs more look into your configuration.

• SPF record errorso nthe domain?
• Routing problems?
• What about your SMTP host name and the reverse name on the IP you use- do they match?
• DO you come from a dynamic IP?

All that can lead to good servers just not wanting to deal with you.
