I can receive, but I'm having trouble sending

This is usually due to the port number used for the SMTP server, or because they don't have authentication turned on. They may also be out of storage space. This is the order in which to check each.

Port 25 Block

  • First, you can have them run a test. Ask them to Go to START on their PC. If Windows XP or lower, click on RUN. If Vista or higher, they'll use the search box at the bottom of the start menu. In the box (in either the run popup, or in the search box), they'll type "cmd" (without the quotes) and hit enter. In the black box that opens, have them type:
   telnet theirdomainname.com 25 <enter>

where thierdomainname.com is their actual domain. Upon hitting enter, one of two things will happen. It will time out (port 25 is blocked!) or it will come up with a screen with text starting with "220-host2.byfcpasites.com...". If they get that, port 25 is not blocked. Move on to the next step.

If port 25 IS blocked, have them get into the Advanced Tab of their mail client. Getting there is handled a variety of ways, but it's with the email account settings. Have them change the port from 25 to 26. Save it, then try a send/receive. If the email goes out, you're all set. If not...

Authentication may not be turned on
In their email account advanced settings in outlook, under the General tab, have them make sure that the "My Server Requires authentication" is checked off, and that the first option "Use same settings as incoming mail server" is selected. Save it and try a send/receive. If it works, you're all set. If not...

They may be out of storage space
If they don't have any room in their personal email account (mail account quota) or if they are out of storage space for the hosting account, the email being sent can't get stored on the server for sending.



Update as of 10/13:


● If you are currently using Outgoing Port 25, please update it to Port 26, as most Internet Service Providers now block port #25. (Incoming Port 110 remains the same)

● If your outgoing mail server is currently set as your domain (ex. yourdomainname.com), please update it to 69.16.233.43

To check your account settings in Outlook:

1. Click the file tab

2. Click ‘Account Settings’

3. Select the email account you are making changes to and click ‘Change’

4. Change your Outgoing Mail Server to 69.16.233.43 (This is likely currently set to yourdomainname.com). Leave Incoming Mail Server settings intact.

5. Under ‘More Settings’ and the ‘Outgoing Server’ tab, verify that your Outgoing Server Port is set to 26.

6. Save changes.
