Sending problems using email program on your computer or mobile device can be caused by a number of different issues:
1. First, double check ALL your settings with those listed Here. If any settings aren't correct, you will receive errors and your email program won't work.
In particular, you should ensure you have outgoing authentication turned on in your email program. If you don't, you will be receiving an error similar to "authentication required", "relaying not allowed" or "mail rejected by server". The setting is usually called something like "my server requires authentication" or "use authentication" in your OUTGOING settings within your email software.
2. Firewalls and security software such as anti-virus programs can often cause problems with email. Try temporarily disabling any firewall/security software you have on your computer to see if that is causing the issue (remember to turn your firewall back on afterwards).
3. Some ISPs block port 25 (the standard port for outgoing emails). If you connect to the internet with one of these ISPs, you won't be able to send emails without changing your settings. If you are unsure whether this applies to you, please contact your ISP and ask if they block port 25.
If your ISP is blocking port 25, you will need to change the following setting in your email program (usually found in the advanced settings):
- Outgoing Mail (SMTP) Port number: 587
This will change the port number from 25 to 587 and you will then be able to send emails.
If the above doesn't solve the issue, please contact us with a description of the problem and the exact/full error message that you receive in your email program. That will help us further determine the cause of the issue.
