Is there a way to do this....? I usually just use my PowerBook at home, so it's connected via Airport to my wireless network using my home broadband settings. My mail program is set up to use the pop3 server of my email provider for incoming mail, and the smtp server of my broadband provider for outgoing mail (my ISP doesn't provide my mail account). So... if i take my powerbook round to someone else's house i have to manually switch my settings to pick up a different wireless network, or connect via dial-up etc. Not too much of a problem. But - if i wanted to send email I'd also have to change the settings of my mail account to use the smtp server of their ISP. I'm assuming that you can use "Network Preferences" to set up different locations (e.g. for different people's houses) to default to the wifi/dial-up connection etc, but is there a way to link the mail server settings to this?
