So something interesting I encountered while working on my site. I use Xampp on a mac OXS Lion to run my website. And I have mail() functions in my code that never worked (sent outgoing mail) before while I was connected to my home internet connection (Verizon Fios).
However, I was recently at a local hospital and logged onto the internet through what seemed to be an unsecure internet connection. While I was working on my site, all of a sudden the mail() functions started working and sending mail... But, when i got back home, it did not work anymore!
How can I figure out what was different, so that I can change some settings maybe in php.ini or maybe my computer configuration, so that I can get it to send mail, like it was doing at the hospital. I am trying to figure it out... any ideas?
