Message from Entourage Fail, but arrive via Outlook 2003

[marcmelk]

Hi.

I have a small business server running Exchange 2003. I use Entourage
and Outlook 2003. My domain is a Custom DynamicDNS domain
(melkonian.net).

One of my clients can not receive email when sent via Entourage. I can
send this client an email from Outlook 2003 without issue, but if I
send an email from Entourage the customer never gets the message.

I am not sure if this is an issue with Entourage mail formatting, a
setting in Exchange, or something on the customers end (which I have no
idea what that item might be).

Here is what I have done to test.

1. Sent email from Entourage to customers primary account and Yahoo
account. Mail arrived at Yahoo account only. No NDR was reported back
to me.

2. Sent email from Outlook 2003 to customers primary account and Yahoo
account. Mail arrived at both accounts.

Any help or suggestions would be great.

Thanks.

Marc

Do you get and delivery failure notification? If not, that indicates the
message got as far as their servers.

I am not sure if this is an issue with Entourage mail formatting, a

Unlikely, but to be sure, set Entourage's mail prefs to 'plain text' and try
again. No server in the word should barf on plain text messages.

Here is what I have done to test.

1. Sent email from Entourage to customers primary account and Yahoo
account. Mail arrived at Yahoo account only. No NDR was reported back
to me.

I suspect it is probably some over-zealous spam filtering at the recipients
servers. Do you have any problems sending to other addresses?
