URLs are added and removed all the time from the uribl.com database.  When a spammer's URL shows up alot in their spam traps then they are added.  Then, when the spamming subsides, they are removed.  I have seen very few, if any, false positives at URIBL so I am willing to bet money that URL was accurately in the database at the time of the rejection.  The only other time that I remember this happening is when a company complained about a rejected email sent from an internet marketing company and it turned out that their URL was indeed on the URIBL black list for legitimate reasons.  I can think of few reasons why this would occur, however, the URIBL list is a DNS based blacklist and so I guess that it would be possible to have these types of problems if there was something sporadically wrong with their DNS lookups.

On most installations, the URIBL black list is more active than spamassassin in blocking spam.  For example, on one of my servers yesterday, 98 spam emails were rejected by the URIBL list while spamassassin only rejected 6 spam.  Nevertheless, if the customer doesn't want the URIBL check then you can disable it by removing all references to it from exim.conf.

FYI,

Gordon
