SMTPswitch
April 15th, 2002[Original Link] Today I release my first ever Mac OS X utility! Wait - don’t get over-excited! It’s a simple bit of AppleScript which changes the SMTP server of all your Mail accounts at once; very handy if, like me, you have several accounts and move between networks frequently. Absolutely no use to anybody else.
Update:This really isn’t necessary on more recent versions of Mac OS X, so I’ve deleted it.
