Using singleinstancestore on a large scale (thousands

thanks for all the replies. I need to clarify a few things. First, we use
sendmail as MTA. We *do* use LMTP and not deliver for the MTA. I'm talking
about something different: when we want to to distribute a mail to all
users or all students, we do so on the server itself, not using the MTA.
As you may or may not know, if you pipe a mail to deliver, you can specify
more than one user as recipient on the command line. Apparently deliver
uses LMTP internally.

Thanks. I suppose I'll just stay below that value.

Separately? In that case singleinstancestore doesn't work, does it?

Right, that's the way I want to do it myself.

I'm still not sure, though, if it's possible to specify thousands of
recipients this way ...
