Can I see the URL of an RSS feed on Apple Mail 4.5?
I cannot find the option.
Once an RSS feed is added to Mail, you cannot see the URL it retrieves anywhere within Mail :(
There does not appear to be any way you can read the configuration using Applescript, looking at the dictionary, the RSS feeds are not accessible either as a distinct entity type or as a Mailbox type.
The only place I can find this information is in ~/Library/Mail/RSS
Each feed is a folder with an .rssmbox extension and inside the folder, the Info.plist contains the URL of the feed.
edit: change reponse re: applescript after further investigation
