Why am I getting around 20 lines of this in a spamassassin --lint -D:
debug: plugin: Mail::SpamAssassin::Plugin::URIDNSBL=HASH(0xa89414c) inhibited further callbacks
What is URIDNSBL and what is this error?
It's not an error, it's a debugging informational message only.. It's highly important to plugin writing and debugging, but otherwise it's irrelevant... Ignore it.
URIDNSBLs are DNS based blacklists of domain names found in spamvertized URI's (aka URL's) from the message body.
surbl.org is the biggest source of URIDNSBLs.
