So at least in my case, I'm running SOGO on a mail server with only 1 account. It gets thousands of messages per day. I had to upgrade the SOGO memory size limit to 10G, it uses about 3G according to the logs. I was trying to duplicate the old Outlook/Exchange workflow. Add rules to Outlook (no concern for whether they run on the server or the client) and let them manage the mailbox on the server. This means hundreds of messages are moved upon receipt to correct subfolders. Messages are deleted automatically, classified as spam automatically, etc. Later if a message in a subfoolder is manually moved, the expectation is that it updates the main server and all other AS clients. As the mailbox has grown, this does not seem to work... many messages seem to just be ignored or missed. So in a normal day, there are hundreds of automatic alerts that come in... probably 20 of them are moved according to outlook, but the SOGO box does not seem them as moved. If a message is moved in a sub-sub-folder in outlook, it does not necessarily get updated in SOGO's view. With Roundcube running on the same maibox infrastructure, its view and SOGO's view are not the same. By SOGO's view, I'm referring to the web client -- this may or may not be AS related. I can provide logs, or make other tests or adjustments, just need some suggestions on where to look. Thanks in advance! -- FF
