If it was only Earthlink and AOL there would be a pattern. There are numerous other ISPs not getting the email sent and some, on all the ISPs, seem to be receiving the emails. This does NOT seem to be the case of an ISP rejecting ALL of these emails sent to their subscribers.
I've put some of the subscribers on a public Topica listserv and all these folks seem to be receiving the email just fine.
I'll send the following summary to CPanel also. Hopefully this is a more comprehensive description of the issue of Not All Scribers Receiving Daily Email
- The mailman list has some 600+ subscribers
- This mailman is part of the CPanel package
- This is a daily (M-F) listserv newsletter. The daily newsletter is only sent out by the moderator.
- The list is fairly stable in size with the usual unsubscriptions and subscriptions, a slight increase each month.
- Mailman had been running fine for months, until Aug/Sep when subscribers started sending messages saying the daily email was not arriving.
- Subscribers NOT receiving their email seem to be consistently the same subscribers. They are from many and varied ISPs including AOL and Earthlink.
- NOT ALL subscribers of any of the ISPs are being rejected. Many subscribers on ALL the ISPs are receiving the daily email just fine.
- Some 250 of the subscribers are now on a Topica listserv. They ALL receive the daily email each day. When the same message is sent to the mailman listserv some of these 250 subscribers do NOT receive the email.
- Emails sent directly to the subscribers, from the same email address that is used to send to the mailman listserv get through just fine, though email sent through mailman does not get to them.
Help is much appreciated.
Thank you, Easy Spokane ===

The cPanel folks have requested that all support issues regarding cPanel be directed to them. Please see <http://www.python.org/cgi-bin/faqw-mm.py?req=show&file=faq06.011.htp>.
Some Earthlink and some AOL subscribers are not receiving their messages others are receiving them fine.
Both Earthlink and AOL could easily be dropping the messages for some recipients, without telling you or the recipient. Both Earthlink and AOL could be implementing anti-spam policies that no one will or can tell you about, because you might be speaking to well-meaning but ignorant people at the service(s) in question. Both Earthlink and AOL tend to have less net-savvy customers who will occasionally click on the wrong button and "report as spam" a legitimate message, or not remember how to unsubscribe themselves and use the "report as spam" button instead.
There's not much you can do about this general class of problem. Please see <http://www.python.org/cgi-bin/faqw-mm.py?req=show&file=faq03.042.htp>.
There does NOT seem to be a pattern yet to those reporting not receiving the daily message.
They're using AOL and Earthlink, that seems to be a pattern to me.

I don't see a personalize option in the Non-digest options page. Just 3 - receive mail immediately, header, footer.

The statement that the list was working fine was intended to mean that the list had been up for months, with people subscribing and unsubscribing etc without any glitches - a 'stable' list of about 630 subscribers. Then missing emails started being reported around September. Perhaps someone else experienced something similar??? And found a solution????????
This is a newsletter of one email per day. Few if anyone receives a digest. When i notice someone with digest set it is turned off.
I'm not sure if mailman is on the same machine. I send to mailman and directly from the same email address. On those that do not receive the daily message - sending a direct message to them works fine.
Bounce-processing is NOW fully turned on. I'll ask the IP provider for the error logs.
If bounce_processing is not on for this list, turn it on. Check the
mailman bounce, smtp, smtp-failure and error logs. Check the MTA logs.
If you don't have access to these things, get your provider to check
them for you.

What is meant by a 'personalized' list. (See the header below for a message that was received.)
If you don't know, then your list probably isn't personalized. If your Mailman installation allows personalization, you will have the option to turn it enable it for a list on the Non-digest options page.
The one subscriber that is on both lists and only receives from the small list is on Earthlink. Earthlink says they are not blocking the list.
If other Earthlink subscribers are receiving the list, then this probably isn't the issue - see below.

Are the lists personalized? If not, messages to the larger list may be caught by spam filters because they have too many recipients. Check the ISPs of those not receiving posts and their spam filtering policies.
If a list is personalized, each recipients message is sent in a separate SMTP transaction because its content may be different in some ways from all the other messages.
It the list is not personalized, messages are sent to a large number of recipients in one SMTP transaction. However this is only the delivery of the message to the outgoing MTA. What happens next depends on the outgoing MTA, but maybe the message is then sent to all the recipients that are in the same domain (e.g. aol.com or earthlink.net) in a single SMTP transaction with the recipients domain. Dan is suggesting that if this transaction has "too many" recipients, it might be rejected. If this is the reason, all the users who aren't getting the posts would be in the same few domains, each of which contained "too many" affected users.

Mailman had been working find on a 600+ subscriber list. Something changed? somewhere?
If you don't know what changed, how could we?
Now more than a few people are not getting their email.
Is delivery enabled for these members? Is there a pattern? E.g. are digest members and only digest members not getting mail?
Sending directly to a subscriber works fine.
From the same machine that Mailman is on?
On another list with 30 subscribers. One subscriber is on both lists. This subscriber receives emails from the 30 subscriber list but not from the 600+ subscriber list.
How can this be fixed?
How can this issue be further isolated so it can be resolved?
If bounce_processing is not on for this list, turn it on. Check the mailman bounce, smtp, smtp-failure and error logs. Check the MTA logs. If you don't have access to these things, get your provider to check them for you.
