Hi Ian, > Cyrus Mailstore does handle final delivery, but there's plenty of > opportunity to handle messages before that point. For example, we now > use Exim and Cyrus Mailstore, and we have plenty of processing going on in > Exim before hand off to Cyrus (with LMTP) including spamassassin, clamav and > Exim filters. There are also processes between the two, for example > Mailman. Very true, but it does not do the processing needed by Outlook. It cannot convert iTip and winmail.dat attachments to the related message objects and do the linking in the Outlook message store. This is where you need the transport mechanism of Outlook.
