There is most likely a problem with your settings.
Here are some places to troubleshoot:
Using the correct outgoing port?
Make sure your outgoing email (SMTP) connection uses port 587. By default, the port is set to 25. However, email sent through this port will be arbitrarily blocked due to all the spam that also gets sent using port 25. Your email will sit in your outbox, sometimes for hours, and then suddenly send.
Need different outgoing servers?
Some high-speed internet service providers require you to use their servers when sending email. If you have such a setup, when you send email it is not going out via your HostPapa account (even though it looks like it does to anyone who receives the email).
If you do have different outgoing servers, check the rest of your email program settings. Your outgoing settings are correct, but there may be something wrong with your incoming settings.
Connecting to the default email account?
The default email account is not a fully functional email account, and cannot send email. It is possible to accidentally connect to it. Your email username is the full email address including the @your_domain.com. Please do not use your cPanel username, as this will connect you to the default email account.
For more information about the default email account, please see: http://hostpapasupport.com/kb/your-default-email-address/
Can’t send from webmail?
Check to see if you are logged in to your default email address. You can tell by checking the very first webmail page. Near the top, it will say “You are logged in as” and then have an email address that looks like your cPanel username@your primary domain name. For example, if your cPanel username is mynif123 and your primary domain is myniftysite.com, your webmail page will say “You are logged in email@example.com.”
Please click the logout icon in the upper right corner. You can then log back in using the following information:
Email: The email address you want to access. Please do not use your cPanel username.
Password: The password specific to the email address you just entered.
How to check your settings
You will need to check the instructions for your specific email program to see how to get to the settings and change them. Here are some articles that may help:
Outlook 2003 and 2007
iPhone and iPod Touch
Here is a link to video tutorials on how to set up connections from a variety of different email programs. These tutorials will show you where you can change the settings listed above.
If you are unsure of your email account password, you can reset it from your cPanel. To do so, please follow these steps:
Log in to your HostPapa dashboard: https://www.hostpapa.com/dashboard
Click on My cPanel. If you have more than one domain associated with your HostPapa account, click on the appropriate domain link, then enter your cPanel password if required.
From the Mail section, click on the Email Accounts icon.
Locate the email address requiring a password change.
You can either create your own password, or use the password generator.
Make sure to keep your new password in a safe place.
Click Change Password.
