Re: [Mailman-Users] Call me Don Quixote... :-(
Update: The smart host rejection problem that was affecting only 1 of the Mailman lists on my server was fixed by my provider. No explanation or email notifying me of the fix was provided... it just started working again Friday morning.

Re: [Mailman-Users] Call me Don Quixote... :-(
This morning I checked the smtp log to see if I could find a match to my daily ping. I did find it today, 1 entry for 156 members.

It is possible that the smarthost started using some kind of look-ahead address verification during incoming SMTP. I.e. they check that the message is deliverable downstream before accepting it from you and if it's not, return a generic 554 Message refused. Note that in the case of the above, they accepted the message from you and then later sent an email reporting the delivery failure. In the case of the 554 Message refused. reports you quoted earlier, they were refusing to accept the message during SMTP from you. How do you authenticate to these servers? Why should they accept and relay your mail? hmmm ... 'cause they accept and relay everything else from the server? :-P (ya gotta have some fun when things go wrong or else you'll go nuts. ;-) ) But why? If I attempt to connect to port 25 on the server at 208.109.80.54, it immediatly closes the connection without sending a greeting. Why doesn't it do this to you? There are lots of possibilities, e.g. - your IP is a known 'good guy' in it's network - you are connecting to some other port - you are connecting via SSL with a certificate it recognizes as a customer - other possibilities I ask why, because the answer might have some bearing on the problem we're trying to understand/solve.

[Mailman-Users] Call me Don Quixote... :-(
I have to impossible dream of have *all* the mailing lists on my server work. So far one of the previously working lists continues to evade all methods of retrieving useful debug information... The other lists on the same server/domain currently seem to be OK, so the only conclusion I have is it's the number of subscribers or my provider is blocking emails out. Digests for the problem list still seem to go out every day. The original problem seemed to be RBL related, but that problem has either been solved or well obscured... Server info: Intel(R) Xeon(R)CPU 5110 @ 1.60GHz Red Hat Fedora Core 7, Linux 2.6.9-023stab043.1-smp Parallels Plesk 9.2.3 Mailman 2.1.9 What hasn't worked: * My service provider claimed the info in disable messages was insufficient for debug!? * I tried to bypass bounce processing by changing the list-bounces alias. Plesk fixed the alias. * I reduced the bounce threshold, now people are kicked off sooner. Today's batch of almost 200 disables returned no useful information! All returned: The triggering bounce notice is attached below. Questions? Contact the Mailman site administrator at mail...@rx7-world.net. [disabled by periodic sweep and cull, no message available] * VERP worked a couple times on my test list, but never on the other lists, even though *sometimes* it did send the messages individually from the standard list-bounce address. I set VERP options: VERP_PERSONALIZED_DELIVERIES = Yes VERP_DELIVERY_INTERVAL = 1 * tried to update from 2.1.9 to 2.1.12, but Mailman requires the Python development package. The latest Python won't install for some obscure reason... (Why my PC running Linux has Python dev. and will install Mailman and the server services I *PAY* for won't is a baffling question...) * couldn't find any useful information in the logfiles.
