The Activity window looks something like this: That one will show you exactly what is going on and who or what is slow. To monitor what is slowing your Apple Mail down open the Activity under Window Tab in Mail. It looks like this on my mac for one of the accounts: If you right click on you gmail account in Apple mail and ask for Account information you will get the limit information you have with the gmail on they server. You can have more space with gmail account by converting it to premium (pay for it).įolder limit is none (as many as you like) In my case I have 2 gmail accounts each with 16 Gig Quota Limits- those are standard gmail accounts. The limit is only what your gmail (Google) account gives you. If you're reaching a Mail-Count of more than 200k, you are probably collecting a decade of mails (unless you are writing a lot).Īfter 3-5 Years you should store those mails on a Backup Server (Maybe at a different location), safe for nobody to access and safe regarding any kind of loss. Also roundcube as a Frontend is much faster when going through severel houndred of thousands of mails. The Server can handle those Mails a lot better than Apple Mail.

In our company we have a Linux Mail-Server and a Roundcube Frontend with a MySQL DB.

I use a OS X (Mail-) Server with a Roundcube Frontend and a MySQL Database. Having your own Server for that helps a lot. Don't go beyond 10k Mails (in your main Postbox).It is not recommended having such a big MailBox at all. In effect, your Hard-Drive storage and the Performance of your Mac are the only limiting factors, not some count of messages in terms of size or number.Īs you already noticed, the app gets really slow with Mails over 100k or even 200k on current hardware (perhaps except the Mac Pro).

The Limit is not something programmed into Mail.
