It is multiple servers so I'll keep watching my logs and then might be able to provide POSTINI with the server or servers giving me a problem...from what ive read here they will not be of much help in resolving this, but we'll see.<br />

Thanks for your help!

<br />
&nbsp;There was a SMTP communication problem with the recipient's email server. &nbsp;Please contact your system administrator.<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &lt;mail.mydomain.com #5.5.0 smtp;550 Requested action not taken: mailbox unavailable or not local&gt;<br />

Interactions between email servers and clients are governed by email protocols. The three most common email protocols are POP, IMAP and MAPI. Most email software operates under one of these (and many products support more than one).  The correct protocol must be selected, and correctly configured, if you want your email account to work.
