Can you be more specific? What do you want spamassassin to check about it? It should already check the URL itself against surbl.org, uribl.com, etc. Or are you suggesting the the triple-t in htttp:// is inhibiting SA's ability to understand that it's a URL? If you're suggesting having it follow the link and download the image for analysis, that's very unwise. This is a great way for spammers to track what messages are being processed, by using custom URLs (ie: web bugs). It's also a great way for them to detect what IPs appear to be fetching them automatically for analysis, and start returning different, potentially slow to process, information to those servers and DoS them.
