On the bright side, there are only 3 specific email settings that you need to focus on. The bad news is that this is a moderately technical topic. The good news is that this problem can usually be fixed by adjusting your email program's settings. On the other hand, you've probably never experienced this problem if you use webmail (accessing your email using an email web site through a web browser like Internet Explorer or Mozilla Firefox or Google Chrome or Safari). This is a growing problem for people who move their computers between different internet connections and use regular email programs. You may also notice that if you use a smartphone or tablet for email (e.g., an iPhone, Android, iPad, etc.), you have no problems receiving or sending, whether you're at home or away, as long as your device can get internet access.

When you get back to your home or office (and your regular internet connection), everything returns to normal, and you can send email again without any problems.However, you get an error when you try to send email, whether you're composing a new message from scratch or replying or forwarding.You then open your regular email client program (Outlook Express, Outlook, Windows Mail, or Eudora on Windows, or Apple Mail or Thunderbird or Eudora on Macintosh, etc.), check your email, and see that you can receive new messages just fine.

Or, you start using the cellular phone system for an internet connection through a 3G or 4G mobile broadband card or hotspot or 'MiFi.'

You connect it to the internet at that location, either by accessing their wireless network or by plugging in a cable they provide.

You take your computer on a trip, or simply across town to a friend's house or coffee shop.
