External relay send connector not resolving sender names RRS feed

  • Question

  • Greetings,

    I have a simple relay connector that works well to send emails outside and inside the organization.

    However, the only issue we have is that when the message reaches the recipient, it arrives as someone@domain.com instead of   Someone Lastname <someone@domain.com>.

    I have an older Exchange 2010 and it has a connector but this one works well. When I check the premissions provided by fl, they are the same. We are testing by connecting directly to the server (no LoadBalancer in between)

    I have many forums but I haven't found an answer.

  • Hi Eve,

    According to your description, my understanding is that the message reaches the recipient which will show sender's smtp address instead of showing the sender's display name. Am i correct?

    If any misunderstanding, please feel free to post back.

    Moreover, please help confirm the following questions, that would give us more clues to help troubleshoot the issue:

    Do only the outside recipient have this issue ?or internal recipient ? or both?

    Does the sender's SMTP address exist in GAL?


    Best Regards,
    Niko Cheng

  • Thank you for your reply.

    Yes you are understanding correctly. The sender name is not displayed, only the address.

    As for your questions

    Yes it is only for external recipients. Internally it works well.

    Yes the address exists, as I am testing it with my own and also two other emails.

    Thanks again,

    Eve

  • Have a look at this.

  • Thank you that was very informative.

    I checked and it's set up to 'True'

    With this new information I created one for a domain (to test) and tweaked some of the options and I still find the same behaviour.

    DisplaySenderName                    : True

  • Hi Eve,

    The message send from internal user to outside user, right?

    For example: UserA@Yourdomain.com send a message to UserB@Outsidedomain.com, UserB receives the message that show the sender as UserA@yourdomain.com instead of UserA<UserA@yourdomian.com>.

  • Yes, that is correct

    For example

    John Peters jpeters@mydomain.com
    sends a smtp message (port 25) internally and you get 'John Peters <jpeters@mydomain.com>' or the exchange equivalent

    If i send to Mary Jones - mjones@outsidedomain.com

    I get a message from jpeters@mydomain.com but no name.

    If i send it from Exchange 2010 I get the whole John Peters <jpeters@mydomain.com>

    I compared and both connectors have the same characteristics.

    Thank you!

    Eve

  • Hi Eve,

    If disable this connector, let the internal user send a message to an outside user directly, does the same issue occur?
