## You can receive emails but cannot send
Many major internet service provides (ISP's) may block outgoing mail server ports to prevent their services being used to send spam emails. The most common port that are blocked is port 25, but for non-SSL settings we do recommend that you use port 26. You should review your email account details (in Outlook / Mac Mail etc.) and adjust if necessary.
## Using Port 26 but this still does not work
Some ISP's may block port 26 as well as port 25. When this happens, you may wish to contact your ISP and discuss whether they can enable a port for you or alternatively receive instructions on what SMTP port or servers you can use that will work through their network. Most commonly, this information will be able in your ISP's FAQ section on their website.
## You cannot receive emails or send emails
If you are unable to send or receive any emails, it is likely that your email account details haven't been set up correctly or they may have changed (especially if you use SSL which has a specific server setup which may have changed). You should review your mail configuration settings as follows:

Scrolling down to the '**Manual Settings**' heading, you will locate the manual settings required for the email account. It is important to review these settings to compare to them to what you are using on your email client. Please note that there are two settings available, secure SSL/TLS and non-SSL. It's important to choose the correct settings that you have opted for.
