Re: Dada Mail Development Focus
I have had a couple of clients complain that emails were not getting to the entire list. I tried to find the reason in the backend but could not.
What I believe caused the problem was the length of time it took Dada to complete the sending task. My host (Hostmonster/Bluehost) only allows limited continuous access to the processor for one process. If something takes longer than that, the system kills it. In the case of Dada, I believe this caused Dada to force the mail into a stale state, which locked the completion of the send process. Compounded were the many backed up emails that never got to the list unless I cleared the stale mail out.
I tried everything I could think of to get around this issue, but could not come up with a solution. This client was using version 3.?? (I don't remember the exact number). I say was because they since moved onto a gmail-based mailing group setup. I couldn't convince them to stay with Dada.
1. I don't know if the host caused this or if it was Dada. Not much was found in the logs.
2. I played with the sending queue, sleep function and everything I though would speed this up.
3. I noticed sending occurred as expected if I stayed logged into the backend and manually watched the sending process. If I left it to cron, it inevitably failed to complete the task.
4. I tried to figure out how to have Dada sending more than one mail out at a time, but could not find the code.
5. I have not played with any of the version 4 iterations, so I don't know if anything has been improved upon as far as speed.
So I supposed my suggestion/wishlist would be:
Faster
More robust system for handling stale mail outs
More grainular control over the sending process
Better/more robust system for automatic mail outs (cron seems to take much longer than the administrative backend of Dada)
I love the system and can't wait to start using it again, as soon as I get a client that has a need.
~regards, and keep up the excellent work!
