Have you ever travelled with your computer and connected to a hotel or a friend/family’s WI-FI and you can download your email just fine, but replies won’t send and you have no idea what’s wrong?
This is usually the result of authentication issues. In order to prevent strangers from using their SMTP server to send spam, many ISPs require users to authenticate when they try to send email while accessing the server from outside the network. In many cases, users will also need to use a different port number and may need to use SSL.
Confirm Outgoing Server Authentication
We are using Outlook as an example, but these settings are standard in most desktop email programs. Please refer to your software vendor for where to access these settings in your email program.
To check or change the outgoing server authentication, you need to open the Account settings dialog. In Outlook 2010 or Outlook 2013, this is on the File tab, and on the Tools menu in Outlook 2007 and earlier versions.
After opening the dialog to the list of email accounts, double click on the email account then click the More Settings dialog and select the Outgoing server tab to check the authentication settings.
Enable My outgoing server (SMTP) requires authentication and select Use the same settings as my incoming mail server. These settings will often work both at home and when traveling.
|Username||Your full e-mail address i.e. email@example.com||Your full email address i.e. firstname.lastname@example.org|
|Incoming Port with SSL Enabled||993||995|
|Outgoing (SMTP) Server||Smtp.1and1.com||smtp.1and1.com|
|Outgoing Port with TLS enabled||587||587|
|Outgoing Server Required Authentication?||Yes||Yes|

Once you make these changes, you should be able to send email from home, coffee shops, or hotels.
If you are unable to get the resolution above to work, there are a couple alternatives.
- A free alternative is to use the online webmail portal at http://webmail.1and1.com and login with your email and password. You will be able to send and receive emails without having to change your email settings on your computer.
- One final option is to consider a paid “on the road” SMTP service such as https://www.smtp2go.com or https://www.authsmtp.com/.
