How do I set up the Mail application?
I have my Mail box set up to the internet through my comcast internet account. I am trying to set it up so I am able to use the Drop Box large file feature. How do I do this? Thanks!
iMac, OS X Yosemite (10.10)
Dropbox, if that is what you are asking about, isn't related to Mail; it's a completely separate program: http://dropbox.com
File attachment size limits aren't a function of Mail either. File size limits are imposed by your email service provider. Sometimes they're 5 MB, sometimes 10 MB. iCloud Mail is 20 MB unless you enable Mail Drop. There are other limitations on its use. See Mailbox size and message sending limits in iCloud - Apple Support.
