Hi everyoneNot quite sure if this is a developer or general 'hacks' forum discussion, but we are now receiving quite a large (50/60 per 1/2 million newsletter) amount of Abuse Reporting Format responses from AOL which are from people who flag the messages as spam (not true!) and we then manually unsubscribe them from our lists. I was about to sit down and roll some custom code to handle these automatically, as we have the unsubscribe link in the body of the email (ARF format doesn't include the reporter's email in the ...Continue Reading

During my optimization pass, I found a massive memory leak that happens during a mass mailing of an HTML message. The mass mailing process potentially starts eating up many hundreds of megs of memory, which could potentially start slowing things way, way down, or even get your sending process killed. This underlying problem could be the culprit of a lot of mysterious sending problems with Dada Mail. I've been able to remove the problem with the development stuff I've been doing and was also able to backport the bug, so ...Continue Reading

Here's the scenario I'm talking about: You archive the old install and install the new version.

The backwards compatibility issue is easily solved by dupllcating, renaming and archiving all the old files including the database.  Then they wouldn't be deleted or overwritten and could be reinstated.  Should have thought of that when I wrote it.I don't understand the below sentenceIt's pretty hard to know what your deliverability is actually with Dada Mail 2x. Do you have any idea (meaning: data)?   Yes we are saying the same thing below, just from a different point of view.  The re ...Continue Reading

Before testing it, I would have to be sure that I would not be changing something that would prevent me from going back to the earlier version. (if it ain't broke, etc)The improvement that has me the most interested in upgrading has not been implemented yet.  It's the changes suggested to Bounce handler in which soft bounces are cleared if mail to a recipient is accepted on subsequent mailings.  There are other nice features, but I've gotten by without them so far.But I'd even forego that fea ...Continue Reading

Actually, depending on what I use to look into this, I get different answers. Using a tool called Devel::NYTProf (which is pretty incredible) it actually gives a dramatic speed improvement: http://dadam ...Continue Reading

You got my attention on this one.I reverted to 2.11.16 quite some time ago because it could send out 25,000 emails about 180kb in size in about an hour, which is about 7 per second. I needed the speed because sometimes I send several in a day.  Subsequent versions took much longer to send.  I'd like to have the advanced features of the newer versions and would update in a heartbeat if the speeds were comparable.FYI: using sendmail, no batches, no gaps; just one big gulp.  It's faster than ...Continue Reading

Hello Everyone, I've been toying (again?) with changing the template engine in Dada Mail (but keeping the syntax the same) from HTML::Template: http://search.cpan.org/dist/HTML-Template/ To HTML::Template::Pro http://search.cpan.org/dist/HTML-Template-Pro/ HTML::Template::Pro promises speedups between 10 and 25x over HTML::Template, which is pretty nice. The downside is that I won't be able to ship Dada Mail with HTML::Template::Pro enabled by default, as HTML::Template;:Pro requires you to compile the module. ...Continue Reading
