I have two accounts set up in Apple Mail. The second account is for backup purposes and because at times the primary account is unavailable. When that happens, I send from the second account but would like the reply-to address to be that of the primary account. Is there a way to set things up this way in Apple Mail?

With a message composition window open in Apple Mail make the following menu selection:

View > Reply-To Address Field

That works for a message-by-message basis. If you want to apply all the time there's a hack you can do this via Terminal:

defaults write com.apple.mail UserHeaders '{"Reply-To" = "reply-to@address"; }'

Just configure both email accounts with the same email address, but different server details and credentials.

You can set the e-mail address in Mail.app Preferences > Accounts for each account individually.

Not all mail servers accept mails with a From: address not in their own domain. –  patrix Aug 16 '12 at 19:34
Possible, but I never encountered an SMTP server with such a restriction. –  Gerry Aug 16 '12 at 20:19
It's used to prevent spam –  patrix Aug 16 '12 at 20:37
