Who has email that does not have web access at the time they get their email?
Granted I suppose it's possible that you would download your mail ahead of time
before leaving home and then opening your laptop on the train.

The load shift is a valid concern, and does change from a 'push' to a 'pull'
format. True: users who have a bland interest in the article that is being
posted will probably not pull down the URL - what's the problem with this, it's
saved bandwidth. Anyone who is /actually/ interested and can take the time to
read/parse through 30k worth of email will take an extra second to click on a
link or do what not to pull up what they want. And I do understand that this
means that a person may actually pull on that link a number of times on
different occasions. However it's now pulling on a webserver rather than
pushing through an email server, which depending on it's configuration may have
as few as one outward connection at a time (which I'm not sure how rare /that/
is, my original sendmail server only had 1 outbound, but my current qmail setup
allows up to 50 outward smtp connections at once), and a webserver is designed
to be pulled on a lot. Most basic configurations will start anywhere from 10 to
20 instances at once, and the 'high bandwidth' demand won't be high at all if
you keep the presentation simple and clean and non-graphicy - just you like
you'd get in a 30k message that got pushed out to you. Plus, if you really want
to get finicky, the manner of processing http requests churns out fewer headers
and data than mail.

Also, unless 100% of your user base is actually reading the article, you're
going to be saving bandwidth (some people may open an article more than just
once, but most will read it once and be done, in which case you will come out a
little bit ahead instead of a lot). The load of an entire batch (rough 300meg
estimate) will also be spread out more over the course of a few days as
everyone checks their mail and may or may not look at that message and cause it
to draw on the url or click/paste it into a browser themselves.


It all boils down to a matter of how you want to use your server. There are as
many good points for as against everything I said and have been responded to
with, however all the items presented have not really made an effect on my
point of view. There are two sides to this debate, the client side (where the
rebuttal for my view came from), and the server side (which I was presenting).


If you want the best of both worlds, perhaps consider doing similar to many
newspapers have done with their web presence/maling list user base. Send out a
smaller email message which briefs the content of the full article and then
present a link at the end which lets users get an idea of the article rather
than flying blind on whether or not to follow the link or not. Cut a 30k
message to 10k users down to maybe 5k in this way and y

If the piece of email is sponsored and has advertising, it's a HUGE problem.

Um, Tib -- I've actually done this and measured it. Have you? You ignored
pretty much all of the data in my message while responding to JC -- and you
still sound like you're guessing at this stuff. Have you actually run
servers in both configurations and measured response like I have? Because my
numbers say you're wrong.

No, it won't. There's a huge peak in the few hours after delivery, which
drops radically after that and stretches out over about ten days or so.

> It all boils down to a matter of how you want to use your server.

And whether you want to pay for peak load capacities on your web server or
the lower, spread out push capacities on your e-mail.

Again, I have to ask. Have you actually done this with large lists? I'm
curious if your numbers disagree with mine, or if you don't have numbers to
back up what you're saying. I'd like to know if the data I've gathered may
or may not be typical. If you've done it, what size lists?

No, but I expect wireless mobile to have limitations on display -- not to

If you're running on a 384k dsl then the only advertising is the stuff you put

Well your numbers aren't my numbers, so of course they'll say I'm wrong, and if
that's all you're intent on proving then feel free to flame/shoot down every

I would think this would be a bit the opposite. For your mail server to push
anything it has to look up records on the domain it's going to send to (which
for 10k users I would assume to be a lot of domains), rather than just firing
back a response to an ip for a data request (and will only lookup and put
resolved host names into your log only if you tell it to do so). Again it would
seem to me that the webserver would have an easier time with the load than the
mail server.

What I have:
A personally built server (PIII 500, 256mb memory, 30g hd)
a 1.1 sdsl line
5 fully hosted domains
23 users (maybe a third of which are decently active for mail and web demands)
5 email lists running on mailman, the largest of which is about 300 users.

Do I run a newsletter like the original topic of this thread was about? Nope.
Am I guessing a little about traffic and how it could happen if changed to the
way I talked about? Yep. I say a little because I used to work for a company
that was completely based off of this kind of newsletter and traffic, to the
tune of about 8 million addresses, 200 mail servers, and about that many web
servers. Dealing with systems on two vastly different scales (millions of users
at my old company, and a handful at my own server - versus 10k towards the
middle of the spectrum) turn experience into best guesses. I have never maxed
out my bandwidth with list traffic, so my comments are /estimates/ of numbers
and /estimates/ on behaviors of people based on myself as being 'joe average'.

[Mailman-Users] no mail delivery

2001-05-13 Thread Hendrik Runte

Dear list-members,

I searched the archives and the whole web without any success. So, you'll understand 
that any help on the following topic will be appreciated:

Trying to install Mailman-2.0.5 failed. Honestly, it's my 6th try, and I think it's 
time to ask some people being more successful. Any try produced these errors: The 
postings are not delivered to the list members. Additionally, a confirmation request 
from any subscriber never arrives at the subscriber's mail account.

This is how I tried to install mailman on a Cobalt RaQ3 with sendmail 8.9.3:

- unpacking, creating mailman:mailman, creating /home/mailman right as shown in the 
installation guide at lists.org

- my options to do ./configure were:
--prefix=/home/mailman
--with-username=mailman
--with-mail-gid=mail
--with-cgi-gid=httpd

- adding a symbolic link to /etc/smrsh:
124920 lrwxrwxrwx   1 root root   26 May 13 14:48 wrapper -> 
/home/mailman/mail/wrapper

- mm_cfg.py:
from Defaults import *

# Site-specific settings
DEFAULT_HOST_NAME   = 'raq.granus.net'
# DEFAULT_URL must end in a slash!
DEFAULT_URL = 'http://www.granus.net/mailman/'
PUBLIC_ARCHIVE_URL  = '/pipermail'
PRIVATE_ARCHIVE_URL = '/mailman/private'

HOME_PAGE = 'index.html'
MAILMAN_OWNER = 'mailman-owner@%s' % DEFAULT_HOST_NAME

SMTPPORT = 25

- doing the last steps to create a site pass, creating a new list ('abc'), copying and 
editing the /etc/aliases like this (and running newaliases successfully):

# Mailman 2.0.5 settings [13.05.01]
mailman:[EMAIL PROTECTED]
mailman-owner:  mailman

## abc mailing list
## created: 13-May-2001 root
abc: "|/etc/smrsh/wrapper post abc"
abc-admin:   "|/etc/smrsh/wrapper mailowner abc"
abc-request: "|/etc/smrsh/wrapper mailcmd abc"
abc-owner:   abc-admin



The GUI runs pretty fine, but trying to subscribe gives no error message but an entry 
like this in /var/log/maillog:
May 13 15:09:50 raq sendmail[32214]: PAA32214: from=, size=0, class=0, pri=0, 
nrcpts=0, proto=ESMTP, relay=localhost [127.0.0.1]

The subscription message never arrives...

Trying to post to the test list returns 'no such user here'.

Does anybody have a clue what I was too blind to see, didn't set properly?


Thanks a lot in advance,

regards,

Hendrik.

This blanket statement is not always correct.  It strongly depends on
the MTA that you are using.

My mailman installation talks to the Windows 2000 SMTP MTA, where
there are no performance problems with having the batching set to a
very high number.  Multiple queues can send out the same message at
the same time.  Using high SMTP_MAX_RCPTS numbers results in a lot
less disk activity and also means that all of my mail going to
hotmail.com or aol.com can get sent in one transaction.

The statement above is true for many Unix MTAs where the queue runner
can only send one message to one file at time.  If you only give the
MTA a couple of messages to party on then it will only be able to talk
to a couple of remote servers at a time, so sending out a single
message could take quite a while.

What this really means is that you should understand how your MTA
works and choose a SMTP_MAX_RCPTS that works well for your MTA.  I
just think that blanket statements such as "500 is way too high for
reasonable performance" should be avoided, as you never know what MTA
the admin is using.

Aye, that's one of my more common performance refrains along with,
"install and use a local cacheing name server!".  Fair dunkum tho --
I'd forgotton the painful side effects of turning of DNS checks for
Sendmail, and had thus ritely assumed that non-DNS-check was a

MTAs are fundamentally disk IO bound.  This is one of the reason
that several large mail houses run their mail spools on silicon
disks (ie hard drives which sit on SCSI busses, and which are made
out of RAM).  Within the bottleneck that is formed by disk IO,
read/write time is a smaller percentage.  open/close/delete occupy
the lion's share of the IO time.  Ergo, volume of data processed is
really not that concerning -- its the NUMBER of data items (spool
entries) processed that is concerning.

The laptop has a Wavelan card.  When its at home it auto-joins the
home network and picks up the mail my server has spooled for it, and
delivers the mail it has waiting for outbound.  I then go to work,
laptop in tow, and (generally) have no more 'net access from the
laptop until I retunr home.  (I'm still not happy with this setup,
but it kinda works ATM).

Given the number of others I see on the train reading mail I'm
nowhere near alone in this (tho our methods will vary on how we got
there -- mine is excessively complex).

Which of course means that your web page must now be WAP friendly
and desktop browser friendly.  Reading the web effectively on a

I wandered over to Akami a few months ago and looked at the graphs
of attack time and decay rates for sites that hit Slashdot.  The
leading edge of the peak is typically measured in single digit
minutes.  The decay rates vary fairly widely depending on the time
of posting, but fall into a small number of basic camps.

There's also the possiblity of using your ISP's MTAs as smarthosts
(which many ISPs actively encourage and some enforce/require).

Yes, and no.

I posit that some MTA's ala Postfix and QMail do a good enough job
that they do solve 80% of the problem, which leave only rather rare

Web server traffic is controllable, bandwidth profiles poorly (users
complain), is unschedulable and tends to be bursty.  Mail traffic is
implicitly controllable, bandwidth profiles easily, is schedulable,
and is as flat as you care to make it.

Not true, but also not really relevant -- I was using it only as an example,

Ah, thanks. You finally admit you don't know and haven't done.

I've done lists up into the seven digit size. We've experimented with URLs
and click-ins. If you're talking about 300 users max, it doesn't matter what
you do. ANYTHING works. It doesn't scale, though.

But believe what you want. Trust your algebra. I suggest you don't sell the
service until you know for sure, though with real numbers.

There's reason to keep the RCPT TO envelope reasonably small to
prevent triggering some ISP's SPAM traps.  Specifically, this
appears to be one of the filter points that AOL uses (and of course
it then drops the caught mail silently without a bounce of warning).

[Mailman-Users] configuration problem

2001-05-13 Thread Joe Copeland

Hi,

I'm trying to set up mailman but I'm not getting something right.

When I go to my mailman site's admin page,
http://www.deangeuls.com/mailman/admin, I can see a list of links that I
have set up with the ./newlist command.  But when I click on one of the
links to administer the list, I get nowhere.

I'm Running RH7.1 and Apache.  Any ideas what's wrong?  I tried installing
off the tarball and the RPM from Red Hat, but I can't get over this big
hump.

Joe

Do you have any details on AOL's spam filters?  None of my AOL
readers have complained about missing email.  It looks like my
largest list has 60 digested and 55 regular AOL members, so
I'm guessing that their spam filter is set to a higher threshold
than that.

[Mailman-Users] Mailman + Qmail + Virtual domain

2001-05-13 Thread Rodrigo Borges Pereira

Hello all.

I installed Mailman on my server, and i want all the lists to run with
domain lists.domain.com.
So i setup DNS, add lists.domain.com to rcpthosts and
lists.domain.com:mailman to virtualdomains under /var/qmail/control.

After that, i create a test list, "newlist testlist".
Then I configured /var/mailman/.qmail-default to use 'qmail-to-mailman.py'.

When i subscribe using the web interface, i do get a e-mail from
"[EMAIL PROTECTED]; on behalf of
[EMAIL PROTECTED]", welcoming me to the list.

However, every time i send a mail to [EMAIL PROTECTED], i get a
bounce from MAILER-DAEMON saying:


Hi. This is the qmail-send program at domain.com.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.

<[EMAIL PROTECTED]>:
Sorry, no mailbox here by that name. (#5.1.1)


A also tried not using 'qmail-to-mailman.py', and used a script that comes
with the program that creates all the .qmail files. Same result.

What i'm i doing wrong?

Any help will be appreciated, tks in advance.

They appear to be using a multi-valued metric for their spam
detection -- and to change their metrics regularly.  See:

It doesn't sound like it makes a huge difference if they are batched
up at once, or if they come very quickly on different messages.

"If a mailing list server sends too much mail in too short a time to a
number of AOL members, AOL will consider it questionable and delete
it."

[Mailman-Users] porblem with one domain

2001-05-13 Thread Boris Krivulin

Hi Guys,

We, xraymedia.com, are setting up mailman (lists.xray.tv).  
In addition we are setting up a mail server supporting web and pop access 
(mail.xray.tv).

Separately they both work fine.  When an xray.tv user ( e.g. [EMAIL PROTECTED]) 
appears as a list member, he/she doesn't receive mass mail. There is one 
exception -- the 'welcome' message and confirmation messages do come. 

Question: why only half works ?  Is the welcome message sending code 
different than the mass-mailing one ?

are there.
