The folks at MacHighway used to be a little secret we'd just let VIP people know about, but we're confident in them - so much, that we'll let everyone know about them for their Dada Mail needs. They're local (to us) and we work and live by Macs, so why not host on them as well? They also have installation instructions for Dada Mail tailored to their servers. Like most every hosting company, you'll want to host your entire site and Dada Mail with them and not just use them for Dada Mail.
MacHighway doesn't have any sending limits - just be within reason and good ettiquette and contact them for more information.
Bluehost recommends Dada Mail, so we'll recommend Bluehost. Do check with them about your email sending limits, it may be low, but if you contact them, they'll tell you how to raise it (to about 500 messages/hour). The above link is a partner referal, so if you click it and sign up, we do get a kickback.
The people at BlueHost were kind enough to give us a testing account for Dada Mail, which helps us ensure that Dada Mail works well on their servers. Thanks, Blue Host!
Hostasaurus recommends Dada Mail, so we'll recommend Hostasaurus. We've had very good experiences dealing with their support people who've always been friendly and helpful.
IvyCat.com offers reliable, Dada-friendly web hosting with lots of other effective features to help make your site a success. Mention Dada in the referral field when signing up for free Dada installation.
Tiger Technologies has been kind enough to give us a testing account for Dada Mail and it helps ensure that Dada Mail works well on their servers. We've also worked closely with clients running moderately busy discussion lists on Tiger Technologies' servers with good luck. We really appreciate the support team at Tiger Technologies and we're pretty happy to be able to suggest them highly for web sites that use Dada Mail.

According to Clook.net, they really, really like Dada Mail and are using it to host lists of the 10,000 - 20,000 size. They tell me there's no limits (within reason, obviously) set on their accounts currently for the amount of messages that can go out in a specific timeframe and that long running server processes, like Dada Mail during a mailing list sending, are allowed to keep on running.
On top of all this, they'll also help you set your Dada Mail to use a separate SMTP server specifially tuned for sending, so even if you're on a shared hosting environment, you can send your messages, without burdening everyone else and the messages will go out at a good pace.
These are three fantastic points that makes these guys a good host for Dada Mail.
Also, according to their shared packages comparison page (the most economical that they offer), they have MySQL and Cronjob support, as well as plenty of POP3 mailboxes you set up, so it looks like whatever you'd like to do with Dada Mail, you can do on these accounts.
They do have a few reasonable points that you must follow (actually, you should always follow these points, no matter where you host):
I also get a sense that they'll be passively monitoring your sending, so if they get a report of abuse regarding your mailing list activity, they'll ask you about it and see if everything is configured correctly and work with you so another report won't happen again.
If you do have a specific question, or if want more information, please contact Clook.net directly.
Ipower - at least the support there says, *who knows* that they don't support the Perl, fork() subroutine. This means you can't send mass mailings. I can't even get mail to send on their servers. Avoid.
According to their own Resource Usage docs for shared hosting, users may not, "Run their own mailing list software, whether custom or packaged."Pair networks do seem to have their own solution they'd like you to use. I'd double check if you have something other than shared hosting, as I have myself installed a ton of Dada Mail's on Pair Servers.
Try to stay away from Yahoo's entry-level hosting. Their support for such programs like Dada Mail is fairly bad.
Unless I'm mistaken, Earthlink still does not have a new enough version of Perl to work with Dada Mail, so it's a no-go.
Dada Mail will probably work just fine on a GoDaddy account - but their hosting company is ridiculously complex and I generally loathe them. I've heard great things about their domain name services, but not so many good things about their hosting..
If you'd like to have your hosting company added to this list, please let us know. When contacting us, please tell us why Dada Mail works well with your hosting setups.
