I'm completely new to XAMPP and Apache (though I have run a different local server before).
I've got my localhost up and running 'out of the box' using the XAMPP Windows Installer. Now I'm trying to test my site locally.
I want to test the sending of e-mails from the site to LOCAL destinations, but I get a message "Warning: mail() [function.mail]: SMTP server response: 553 We do not relay non-local mail, sorry. in..."
I've got Mercury ON, but am confused by all the configuration options. I expect I've got to tell it what domains it should regard as local and arrange for e-mails to be sent either to Thunderbird (my normal client) or Outlook Express. But I'm not sure how. I have looked at the Help but so far haven't got it right.
Any suggestions, please ?
