Mailman seems to be continually retrying sending mail to hosts which can't be resolved via the DNS. Is this correct? Also why is it that Mailman seems to invoke sendmail in such a way that it causes sendmail to return a failure on hostnames that can't be resolved (presumably a temporary condition) rather than just passing the message to sendmail and letting sendmail do all the retries itself (which is how most mailers invoke sendmail). I imagine this must relate to the program's needing more detailed info about the state of each message to be sent, but when you tie this in with the default frequency of its retries, it's very strange. ------------------ Leonard Jacobs www.mandala-designs.com (508) 359-5473 ------------------------------------------------------ Mailman-Users maillist - [EMAIL PROTECTED] http://www.python.org/mailman/listinfo/mailman-users
