First and foremost, I don't make Dada Mail to go as fast as possible.
I don't do that because the bottle neck is never Dada Mail, it's the
actually mailing part - where you send the message off to your mail
server. You're 1800 messages an hour is about 2 messages/second.
That's probably on ball with how fast the mail server can take
messages. I'm not at all worried about that.

You can test my theory by, instead of sending a message to your mail
server, using the sendmail command, instead send it to, just a file
that gets appended. Change the config variable $MASS_MAIL_SETTINGS
from what it probably is set to:


$MASS_MAIL_SETTINGS = "|$MAILPROG -t";

to something like this:

$MASS_MAIL_SETTINGS = ">>/dev/null";

Send a message out (nothing will actually get sent out) and tell me
how fast messages are going out. If it's more like 18,000 messages/
hour, instead of 1800 messages an hour - guess what? It's not Dada
Mail, it's the sendmail command taking 2 seconds a messages - and
that's it.

Make sure to change back this variable, when you really want to send
out a message.

If it's sendmail taking so long - there's not much I can do. You can
try this:

which means switching to SMTP sending. That's all I got for you.

I know, John, you like to report sending speed problems, but a lot of
your reports are without much evidence - error logs and the like and
you then don't like trying out a lot of the changes I make. This
report, for example, is basically the same report you gave a few
months ago. My answer is pretty similar, as well. If you're asking me
to jump, I'm going to tell you, "I'm jumping" and not, "how high" -
there's nothing I can do, internally, in Dada Mail to speed up sending.

I don't want it to be a, "He said, she said" thing with Westhost,
where they say they haven't changed anything on their side, so it must
be on Dada Mail's side - it gets us nowhere. Are there major, huge,
ginormous changes in Dada Mail 3, when compared to 2? Yes. A lot. Can
I go back to how 2 worked? I can't, unless you want to get ride of all
the subscriber fields stuff and all the mailing monitor stuff in 3. If
those aren't important to you - use 2.x. Especially with this version
- which is just an incremental *bug fix* version of Dada Mail to be as
compatible with 3.0 as possible, I don't have much leeway to make huge
changes to the architecture within Dada Mail.

I guess a question, *I* would love to ask is, "What is it, that you
all - everyone, would like me to do?", when it comes to the issue of
mail sending? No one has any ideas, really. I ask for comments on what
major feature you all - everyone, wants and no one said, "I want mail
sending super fast!". It was even on the list of things, in the form
of what's called, "Envelope Sending", but not many people said, "hey,
that's a great idea"

A lot of my concentration, in Dada Mail, is not with sending super
fast - a lot of my concentration has been around getting the people
who have limits of sending at only 500 messages an hour realistically
working, thus the whole sending monitor stuff - which is a very
complex bit of code - almost too complex. But it's not so complex as
to add 2 *seconds* of overhead per message. That's just silly,
