Hi David, Exim is an SMTP server. Mail clients don’t use SMTP to download mail, they use SMTP to send mail. They use IMAP, or a Microsoft proprietary protocol, or POP3 to download mail.
It’s a very strange requirement, and I don’t know of any IMAP server which would limit the number of downloaded messages: they just do what the clients ask. BTW: displaying 3000 messages doesn’t imply downloading them. A good IMAP client will download only the headers (Outlook isn’t a good IMAP client). Mulberry hasn’t seen much development for a long while, but can be configured quite flexibly. > On 16 Jun 2015, at 15:39, David Byrne <[email protected]> wrote: > > Hi all, > > We have a client who has a large number (1000+) of users, sending ~25,000 > emails per day.
