I can receive e-mails but I can't send...!

[muzik]

I am sure that all settings are true in Outlook Express. I can receive incoming e-mails but why I can't send any e-mail.

Here is the error number: 0800CCC0F

Thanks

Typically, this kind of problem comes from the SMTP authentification option.

You must activate the SMTP authentification option on your Outlook or equivalent software.

This means that your soft must provide authentification also when it sends emails.

I know that and I already activated SMTP auth. But it still dosn't work. So what can I do?

Check your /var/log/exim/mainlog while attempting to send email, to see if the mail is even getting to your server.

If it's not, then problem is that your ISP is blocking outgoing port 25 connections.

That's very common, and if your ISP is doing that your best bet is to use the ISP's mail server for outgoing email.

Try this is ISP or firewall block port 25 for Smtp service, use alternative port tcp (587)

Check you have check my connection to smtp server require authenticacion: select same setting as my incoming

If you want to implement port 587 as the authenticated email port for exim, the easiest way is to install SpamBlocker2, which installs authenticated email over port 587.

I traditionally use POP-Before-SMTP, which then allows people to use SMTP after logging via POP.

Most Email programs will 'check Email' first, thus it becomes a no brainer for users.

Look for /usr/local/directadmin/da-popb4smtp

The easiest way to test if your ISP is blocking the port is to try
telnet mail.yoursite.com 25
in a command prompt. If you can connect, the problem is elsewhere. If you get some kind of connection failed error, then the problem is that your ISP (or maybe a local firewall, but probably the ISP) is blocking SMTP.
