Currently all of my clients receive email to their Exchange servers from my DirectAdmin/Exim server via POP3 Connectors. This works OK especially since inbound email is screened by SpamBlocker prior to reaching the user's Exim mailbox (and then eventually reaches the Exchange mailbox).
There are situations, however, where it'd be nice to have inbound email screened by SpamBlocker then passed on immediately to a client's Exchange server via SMTP (instead of POP).
Is this possible? If so, how?
P.S. Yes, I know I could change the MX to point email directly to the Exchange box (completely bypassing the DirectAdmin server itself) but then I'd lose the benefit of using my DirectAdmin box as a spam filter before it reaches my client's server. I'd prefer to use my DirectAdmin box as a spam filter instead of implementing a spam filter server on my client's location or within their Exchange server itself (e.g. GFI MailEssentials).
