follow up: help request: new 1300 member list results inmostly bounces
After getting some advice from the list - specifically Mark - last week, I asked the hosting provider if there was in fact some limit on outgoing mail, or some other setting on their end which might be causing the bounces I'm getting. (see previous post for details, but basically, I set up a new mailman list with around 1300 subscribers and as best I could tell - without going through ALL of them one by one - most bounced. I did sample 30 addresses, of which 29 bounced).
Below is the response from the host. They seem to feel it's all on the recipient's end. Does this make sense? or is it passing the buck?
They suggest sending out 10-15 emails at a time - is there a way to set mailman up to do this? (and would there be a point?)
Thanks again for your help.
Nathan
There is really no cap as to how many emails you can send out. However, the more you send out at one time the more likelly they are to bounce. It has nothing to do with Globaltap, it has alot to do with the servers that are recieving the email. There is a marker in the email that marks it as bulk. Most servers including Globaltaps often rejects those emails to protect their/our customers from spam. Comcast and aol also do the same thing. For the most part most mail servers use the same filters and black lists. So the more mail you send out at one time the more likelly that most of them will get rejected by recieving server and bounce. It also creates a possiblity that an entire ip block will get black listed. Which means that ALL your mail will get rejected, but also ALL other of our customers on the same ip block as you will get black listed as well. I'm sure you have a valid subscriber list, but the recieving server has no way of knowing that. For all they know you're just another guy peddling viagra. OK, there are options. 1. You can set up to send out no more then 10-15 emails at a time. 2. There is an organization that can certify your email as not spam. The ceritification is inserted in to the header of your email and then the bulk delivery should get accepted by most other servers, but still not all. And the cerification isn't free.
Most hosting services frown on people who send out large bulk emails. It tends to cause problems for other customers and it takes alot of time to clean up the mess plus explain to other customers why they are not able to send mail for upto a week. In those cases you could be held liable for the "clean up" and loss of revenue.

The SMTP_MAX_RCPTS setting can control the number of emails sent at a time. Others with more experience can comment on the worth of doing this.

I have a Comcast address and I receive a lot of mail from mailman run lists which contain the Precedence: bulk header. If Globaltap is saying that most servers reject mail with those headers I think they're wrong on that.

I'm calling bull$#!+ on this one. First off, plenty of sites run Mailman-hosted mailing lists with thousands, tens of thousands, or even hundreds of thousands of subscribers, and they don't have these kinds of problems. Secondly, if rate-limiting does solve the problem, then you should seriously consider finding another provider.

<BEEEEEEEEEEEEEEEEEEEEEEEP> Wrong answer. Thanks for playing.
Mailman does intentionally add a header for "Precedence: Bulk" to all outgoing messages, as is appropriate for the function that it is performing. However, I've been involved in running mail services at a good number of sites in the world, and I have never, ever heard of any site being stupid enough to filter based on this header.
If this were a problem, then all the Mailman-hosted mailing lists with tens of thousands or hundreds of thousands of users would never have been able to get off the ground.
Most servers including Globaltaps oftenrejects those emails to protect their/our customers from spam. Comcast and aol also do the same thing.
No, AOL doesn't. I was the Sr. Internet Mail Administrator for AOL, and I know perfectly well how they operate, since I helped define most of those procedures.
Anyone else in the world who claims that they know how AOL operates without having personal experience at AOL, or without having direct recent contact with the guys at AOL, is simply blowing smoke up your skirt.
For the most part most mail serversuse the same filters and black lists.
Rate-based activity has nothing to do with filters or black lists. Again, clearly a sign of someone who knows the buzzwords but doesn't understand how the technology actually works.
As for most of the rest of this crap, I'm not even going to bother. Clearly, they need to steal several clues, since they don't have any themselves and it doesn't appear likely that anyone else is going to give, sell, or loan them any.
2. There is an organization thatcan certify your email as not spam. The ceritification is inserted in to the header of your email and then the bulk delivery should get accepted by most other servers, but still not all. And the cerification isn't free.
Talking about Goodmail? Maybe you might want to do some Googling on the phrase "AOL e-mail tax" and see what the community *really* thinks of this idea.

Hint: If your hosting provider is sounding this threatening to you over a small mailing list, you should seriously consider getting a different hosting provider.

Actually, Precedence: list
(As copied from the message I'm replying to.)
This doesn't change the argument (much), and I agree with Brad's points.

Brad has addressed this response from the host, and I agree with Brad with one minor exception. The header Mailman adds is 'Precedence: list', not 'Precedence: bulk', but as Brad and Todd both point out, mail in not generally bounced because of this header.
They suggest sending out 10-15 emails at a time - is there a way to set mailman up to do this? (and would there be a point?)
Todd mentioned setting SMTP_MAX_RCPTS. This may help, but as I recall, you said in your original post that you are dealing with Mailman hosted by the same host that gave the bogus reply to your inquiry. So you have no control over these 'site' settings.
Thus, the situation appears to be that that this host offers Mailman lists as a service to it's customers, but they are unwilling and or unable to make it work, and when you ask for help they offer threats that you can get into trouble for using it.
Note that 1300 is a modest list size for a Mailman list. You certainly aren't asking anything out of the ordinary here. If you are interested in getting this to work with this host, you are going to have to try to escalate this to a management level within the host that cares that they are offering a service that doesn't work, and if that is unsuccessful, Your friend should take her business elsewhere.
BTW, Since you are just setting up, you can do the following:
Mass remove the 1300 members (with notifications set to No).
Go to the Bounce processing options and set bounce_score_threshold to 1.0 (or less). Be sure bounce_notify_owner_on_disable is set to Yes.
Mass subscribe the 1300 (with notifications set to No)
Send a post.
This time every bounce will result in a disable, and the owner will be notified, and the notice will include the bounce.
This may help in your discussions with the host.
Finally, after the problem is resolved, you can remove the 1300 members and re-add them with a welcome message if it is important that they get that (their passwords will change when you remove and re-add them). The remove and re-add is the easiest way to reset their bouncing status in this case.

Mark, Todd, Brad, John, Thanks very much for your advice. It seems like we're dealing with an uninformed host here, and it would be an uphill battle all the way to get this thing working. While she will probably continuing the webhost, I think we'll look elsewhere for a mailing list option. It's unfortunate that a nice piece of software like mailman can be crippled by poor hosting.
Again, I really appreciate all the help.
