SYMPTOMS
After opening e-mail that includes an Internet Read Request (IRR), you notice that there is mail stuck in the Outbox. You may also receive mail that references the error code 550 followed by some explanatory text.



CAUSE
The SMTP mail server does not have the ability to process the header item, Mail From: <> because it is based on an outdated RFC821 that used a conflicting programming example. You will only see this on old SMTP servers.



RESOLUTION
Turn off processing of read receipt requests, or upgrade the SMTP mail server.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.



MORE INFORMATION
Other than having your Internet Service Provider (ISP) upgrade the SMTP server, the only way to keep these messages from filling your Outbox is to select the option Never send a response. To set this, use the following steps:


 * 1) On the Tools menu, click Options.
 * 2) On the Preferences tab, click E-mail Options, and then click Tracking Options.
 * 3) Click to select Never send a response.
 * 4) Click OK, OK, and OK.

By setting this option, requested read receipts will not be sent.
