One of the nice things about MailMate is the great search options and instant response, but that comes at the price of having a local copy of your email, and no doubt many of you have multiple mailboxes, as I do.
<br>
So on my 250GB SSD root volume I have just about 50GB now used by MailMate and I am fast running out of disk space. So I thought since “/Users/xxx/Library/Application Support/MailMate/Messages” is an alias pointing at the mail store of “/Users/xxx/Library/Application Support/MailMate/Messages.noindex” this would not be a problem. I could just copy the mail store to a different external SSD and have a new alias to it (called Messages).
<br>
Some hours later, having made the copy (and deleted the original because of the afore mentioned lack of space), I restarted MailMate. It bombed.
<br>
Copy the files back to the “Users/xxx/Library/Application Support/MailMate folder, recreate the original alias, no problems and MailMate starts up.
<br>
Anyone have any suggestions why this did not work?
<br>
Raza
