Need to ignore external resources during email content extraction

Durning email msg extraction of content the application seems to hang. This is due to fact the body of the email has over one hundred external resources image tags which are for example blank.gif somewhere on the internet. Also, some of these may even not be accessible and are behind corporate firewalls. Is there something similar to HandleResourceLoading for Aspose.Words?

Thank you for your request. Could you share the simple hanging code example for extracting email content, please?
