I'm not sure how well MailHost scales, but you can certainly store thousands of names in a ZODB-managed list. Tests done for the BTreeFolder product prove it.
Sadly, I think MailHost doesn't scale too well :-(
What it'd need to do if you're sending the mail to a few thousand people is to be non-blocking. IIRC, currently, a method/page with a <dtml-in addresses><sendmail></dtml-in> tag pair in it will only return when the mail has been sent to all the recipients. So, if the mails going to lots of people, the page takes ages to return.
Perhaps it would be better to solve this by configuring your sendmail (or other SMTP MTA) to be non-blocking, i.e. store-and-forward. Also you could send just one message to all the recipients instead of sending individual messages.
This is the problem I had where our mail server was taking lots of time to send messages (it was doing lots of stuff to make sure the address was valid) so submitting posts on Squishdot.org was taking ages too.
What, IMHO, is really needed is a mailhost/sendmail tag type thing that gets a message and a list of addresses to send it to. If it could do that in a seperate thread/process/whatever so that whatever calls it doesn't block, that'd be great. Of course, it'd need to have a 'hook back' method provided so any errors that occured could be dealt with.
I wonder how mailman does this stuff and if the code could be borrowed for Zope?
Maybe you could just use mailman as MTA, greating temporary mailing-lists. -------- Hannu
