WifiSmtp grabs SMTP server info while you're using AirPort.

Don't you hate it when you are connected to a WiFi hotspot but you can't send e-mails because the ISP prevents you from using any other SMTP server than its own (and you usually don't know its address) ?

WifiSmtp tells you:

  • the name of the Internet Service Provider (ISP) you are connected to
  • the address of that ISP's mail server (SMTP)
  • the connection speed (available bandwidth)
It can also:
  • copy the address of the SMTP server to the clipboard (so that you can paste it into you favorite e-mail software)
  • more...

What's New

Version 1.1.1:
  • Changed URL of database update file
  • Updated the local database (inside the application package)
  • Made the e-mail reports (uknown or incorrect ISP) a little clearer and added some debugging information
  • Known bugs:
    • An error -1762 (that you can safely ignore) can randomly appear
    • ISP identification in South America and Africa barely works, or more...


Mac OS X 10.3.9 or later

Even though this app gives you the addy of the smtp server..You are not going to be able to send out on it. Why? Cause you don't have an account with them. Thats why Port # 25 is blocked. The best thing you can do is get a Google mail account, .Google gives you free access to an smtp server on port #587..This works 80-90% of the time if your on a laptop and traveling..

um.... why not just change the port your smtp server is using?

my mail server recognizes port 26 as well as port 25. port 587 is also popular. ISP send mail blocking is usually nothing any more sophisticated than just blocking port 25.
