How To Filter Emails Whose Return Address Is Invalid. RRS feed

  • Question

  • Outlook 2010 x32 running on local machine

    I have noticed an uptick in phishing with a false return address that includes my domain.  For example if my domain is mydomain.com I will see return addresses such as Larry@mydomain.com which does not exist in my post office.

    Is there a way to setup a filter or VBA code that will check incoming emails and route ones with invalid return addresses to the junk e-mail folder?  Any API call to validate that an email address exists?

    In my option, there is no built-in API to check the email address. Is your address is a Microsoft Exchange account, if so, I think you could check the email address whether it is list in Address Book. Or, I think you could create a list of address whose domain is mydomain.com, and then check the incoming email address whether it is list in this address in Application.NewMail Event (Outlook). And, if it is not in the list, move it to junk folder.

  • Cannot add code to post office.  All code must be on client side.

    Address Book is by user so not all valid addresses would be all address books.

    Maintaining a list would be a maintenance nightmare as email addresses are added and removed.

  • Hi saberman,

    Sorry for less help.

    If this is a new feature you want to include in the future version of Outlook, I would suggest you submit a feedback in the link below:

    You have to be kidding.  Microsoft ignores almost all (maybe all) of the items posted there.  As near as I can tell Microsoft's presence on uservoice.com was setup so all users could vent instead of doing it in the TechNet forums.  It is a public relations stunt not an actually request for input.  Users would be better off venting on yelp.com.  At least other users would get warnings about all of the problems with Microsoft software that Microsoft tries to sweep under the rug.

    I have opened incident reports with Microsoft just to have them acknowledged as bugs and then closed without fixing.  If you open an incident report and level 1 acknowledges it is a bug it disappears without Microsoft fixing it.  You are not even allowed the option of paying Microsoft to fix a bug in their software even if it damages your retail product.

  • Hi saberman,

    Thanks for your post.

    Due to the limitation of the community support channel, for new features or bugs, I could only provide you uservoice. If it did not meet your requirement or it is urgent, you will need to contact the Microsoft professional support so that our engineers can work closely with you.

    Best Regards,

    Edward

    I have done that in the past.  But they just said it was a bug and then closed it without fixing it.

    As to contacting them for a feature that would require agreeing to pay for whatever hours somebody sleeping somewhere billed against it at an outrageous rate.  I would write an add-on for Outlook to do what I want but Microsoft would probably break it in the next release or via an update.
