There may be a few reasons why you are unable to send email:
- Make sure that your outgoing mail server on your POP client is pointing to smtp.yourdomainname.com (where yourdomainname.com is your domain name).
- Some Internet providers have started blocking port 25 in an attempt to help prevent direct to MX spamming, and abuse of open proxies and relays from their dialup and broadband customers.
This causes email clients not to be able to contact the hosting account mail server directly to send outbound emails. Receiving emails, though, works fine.
To get around this, customers are having to put their ISP's mail server name into their mail client settings on their pc so the mail can then be forwarded from the ISP's mail server to their hosting account's mail server and on to the recipient. The email still shows it's from the correct sender's mail address - not the ISP's domain name.
Here is a list of some of the major ISPs that do this and their mail server names:

- If you are trying to send to a Hotmail, Yahoo, Gmail or other externally hosted account and the emails are not being delivered to the respective inbox, please check the spam, junk or bulk folder.
NOTE: As an alternative to checking your mail using a POP client we suggest that you use Horde or Squirrel Mail available from inside your CPanel under "Email".
