Problem receiving message forwarded from Internet e-mail account

[Matt Fulks]

I have one mailbox that is setup to receive messages forwarded from an Internet e-mail account. When that user sends a message to their Internet account via Exchange, the message gets stuck in the Outbound queue as "Host Unreachable" with their Exchange account listed in the recipients. It seems that somewhere [email protected] is translated to [email protected] before the account leaves our site. There are no errors in either the Application or System logs.

I'm a little confused as to who is sending what where, but it sound like a dns issue.

I'm not sure exactly how you have the mailbox set up to get messages forwarded from the internet account -- is this a server-side rule at the outside account; or is your local user using the Internet E-mail service in his Outlook profile; or is this a separate mailbox on your Exchange server?

It sounds like you have a separate mailbox, and it also sounds like that mailbox has the [email protected] address associated with it (listed as one of the entries in the E-mail addresses tab within Exchange administrator), as well as the [email protected] address. If the [email protected] address is the primary address (in bold), the Exchange server will make the translation that you're seeing.

Is this an accurate picture, or have I made some wrong assumptions?

The Internet account is setup to forward from their e-mail to ours. There is nothing in the Exchange e-mail properties for the outside Internet account. There is nothing set in Outlook to access the Internet account.

Okay, I think I understand the situation better now. You have a user who's got one Exchange mailbox, [email protected]. This person also has an external e-mail account, [email protected]. The [email protected] account is configured to forward e-mail to the [email protected] account.

So the question is: When sending an e-mail FROM [email protected] TO [email protected], at what point is the e-mail address getting changed?

If another user on another workstation sends an e-mail to the [email protected] account, does the re-addressing still occur?
-If so, there may be an entry in the global address list that has [email protected] as one of its e-mail addresses. The e-mail in the user's Sent Items folder should show the display name from the global address book to who it wants to deliver the message to, which should save tons of time otherwise spent combing through the GAL.
-If not, check the original user's contacts folder and personal address book for any entries with the [email protected] address.

Hope this helps,

The problem only seems to occur when a mailing list is used with the users internet account. If [email protected] sends an e-mail to [email protected] the message seems to go through fine. However if [email protected] sends a message to [email protected] the message that should go to [email protected] is not delivered. The internet account is a Notes account that is forwarded via SMTP to [email protected]. I am starting to believe the problem lies within Notes, not Exchange
