Email being falsely rejected as spam when using Image in Outlook signature

Hi Experts,

I have a problem that is causing some issues. Recently some emails have not been delivered to clients because the email has been classified as spam. The signature on the email contains a 36k jpeg, when this is removed it seems to be sent correctly. The image signature seems to work for most people, it is only a few that have issues. The email client is Outlook 2007. I believe exchange is 2007.

I have attached the diagnostic information below, please can you offer any advice so that I can prevent this from happening in the future.

What does the 1.00 spam hits mean?

Many thanks,

Simon.

The recipients need to add the sender email address to the whitelist (if Outlook then it's normally sufficient to add the sender to Contacts)

If I am emailing someone for the first time, then I need to be sure the email is going to be delivered. It is not practical to ask every recipient to add an email address to a whitelist.

If the image is removed from the signature, there is no problem with the email. If the image is in the signature then the email is rejected. I would like to know why an image in the signature will cause the email to be rejected for a few recipients.

Thanks,

Simon

Hello si_marshall1972,

Instead of sending the image, put the image in a server on the internet.  Then put the link to the image in your signature.  Then the email and signature should go through and not be flagged as spam.

Hope this helps!
