SMTP Issues with Exch 2010 RRS feed

  • Question

  • Mail has been intermittent today. 

    Sent mail sometimes does or does not reach recipients, although it does show up int the sent area of Outlook.

    The message in the event viewer is: Send connector SMTP-Out: the connection to IPINFOHERE:25 was disconnected by the remote server. This does not seem like it is the right SMTP server as I recall, and cannot find the SMTP IP info in the console (not that experienced in Exchange).

    Hyper-V machine hosted on a Server 2008R2 box.

    It also seems like the old crashed Exchange server is showing up in the AD. It was not recovered during a crash, so cannot be "uninstalled"

  • Hi John,

    Does this issue occur only in Outlook? Please use OWA to have a check.

    Warning Event ID 2006 indicates that the specified Send Connector was disconnected form the remote server. The Disconnection was initiated by the remote server.

    To solve this warning, please try to:

    1. Verify the availability of the remote server.

    2. Adjust the inbound connection limits on the remote server.

  • Thanks for the follow up.

    When I send a message from OWA, it stays in the draft box.

    Also, I was pretty sure I am not using a remote server to send, rather, using the local Exchange box with SMTP connector enabled, so not sure how I could control the remote settings?

  • Hi John,

    Thanks for your update.

    Mailflow issue occur on OWA, it seems an issue on the connectivity.

    I notice "Sent mail sometimes does or does not reach recipients" and the warning message in your first post, does it mean that sometimes mailflow is fine?

    If it is the case, does this issue occur on a specific time? How about the network traffic status on that specific time?

    Please also try to check whether Port 25 is available.

    Please use following article to test SMTP communication:
