I found several mails on my system that get 2.5 points bei URIBL_DBL_SPAM. But if I check these mails manually none of the URIs inside the mails are listed at uribl.com. How can I show the URIs in the log if this rule triggers?
I found the solution myself. Seems that I just was some kind of "blind"
The URI is shown directly in the mail-header where the spam detection results are shown.
