Isn't there a way for SURBL to detect these encoded redirect destination URLs and check those (without the prepended redirector)?
Well technically SURBLs are lists. They don't detect anything by themselves. ;-) However programs that use SURBLs such as SpamAssassin's urirhs* and SpamCopURI do handle redirection sites:
http://www.surbl.org/faq.html#redirect
SpamAssassin programs such as SpamCopURI and urirhdbl that use SURBLs are capable of handling redirections to differing degrees. SpamCopURI 0.14 uses LWP to get Location information to untangle up to four levels of redirection sites without actually visiting the sites. URIDNSBL's urirhsbl includes patterns to extract the final domains from some redirection URIs. Further development will probably improve the handling of redirection sites.
Other programs may have similar or different strategies for handling redirection or not do anything special at all. If anyone has info about other programs, let us/me know and I'll add it to the FAQ.
