John,

It is S-L-O-W!

It's sending at the rate of under 1800 per hour.  With 18,000 to send it will take over ten hours.  This is not workable.  I cannot send a second msg in the same day.

Reference:  Dada 3.01pro.  External config.  MySQL backend.  I have tried it with the batch sending set to 180 with a one second pause or to not have it set to send in batches or with any pauses.  No difference.

Wha' happened?

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,

I just checked my archives and back in Aprll, I sent 19, 600 in 58 mins total (vers 2.x, which was typical at that time). Sending rates have been decreasing since then, with the largest drop on this edition.

I called Westhost support and was told that they have not made any changes to the mail servers.  Further, they said that while watching the output, that there were few messages in the queue; that Dada was not keeping up with sendmail.

Dada Mail 3.0.1 is released after a good long bug-release cycle, where we squashed about 23 (reported) bugs. There's probably a bit more, but that's how it goes.
