Well, it cannot wait forever. Something must time out, if a queried server does not respond. Otherwise, SIMS might not ever accept any mail, if just one RBL server is down. I guess my question should have been: What is the timeout on a RBL query and, if other RBLs report no problem, will SIMS accept mail in the absence of some responses? > > >>I then add the address of this daemon to my RBL list and thereby implement >>a 30-second delay which SIMS is otherwise not capable of.

Just a DNS server >that takes 30 seconds to say "I dunno". Anyone know how to implement this? Perhaps, come up with URLs for 5, 10, 15, 20, 25 and 30-second delays. The Users of SIMS and other servers without the built-in ability to add a SMTP delay could then choose the delay desired based on the URL. > >Imagine if every SMTP server had a tarpit. Yeah, if a general-purpose daemon, as described above, could just wait X seconds before responding, then every SMTP server *could* have a tarpit. Certainly there's gotta be someone at one of the better RBLs who would be receptive to implementing this... Whom do I contact, hat in hand, and ask for this pittance? ;) ############################################################# This message is sent to you because you are subscribed to the mailing list <[EMAIL PROTECTED]>.
