I'm trying out www servage net as a webhost, and found that their mailing list feature doesn't support discussion lists, so I'm trying Dada Mail It seems to do what I want (it's unusual to find an open-source app that's so bug-free and well documented, fantastic!) but there are a few unusual features with this host:

1. Servage use 'clustered' hosting and there's no SSH access, which can make debugging a little difficult I've seen occasional 500 errors using Dada Mail, but pages always refresh successfully I haven't seen the errors since configuring absolute paths in mail cgi, but that may be coincidence

2. CRON jobs can't be more frequent than one per hour, and to achieve that you have to manually set up 24 'daily' jobs at hourly intervals, which is a bit of a pain

3. The sending limit is 100 messages per minute, which is unusually generous Anything legal is allowed (including, unusually, 'adult' messages) Their supplied announce-only mailing lists seem to run much slower than this, so Dada Mail is a good alternative for them as well

4. Batch sending stops after the first batch (sleep() not allowed?) if the sending window isn't open Leaving the window open isn't really practical for discussion lists, so here's an improvement request: could auto_pickup be incorporated into dada_bridge? It's not a big problem though, because discussion lists tend to have less than 100 members anyway

5. Servage don't seem to support HTML::Scrubber, so archiving discussion list messages would be a security risk (I didn't want to archive them, so I haven't persued this )

I do have one other improvement suggestion: Could a link to the complete documentation (local or remote) be added prominently to all the admin pages somewhere? I keep forgetting where it is
