URGENT!!!! Phpmailer e-mail issues under Linux

I sent the message with Phpmailer, the local test was successful, and placed under the Linux server, the following error occurred

Found a lot of information on the Internet.
1, @fsockopen changed to @pfsockopen
2. SMTP changed to SMTP
3. Firewall blocking
But all modified, the Linux server firewall stopped, or reported the above error, there are other ways to solve it?
Emergency......

First make sure the network is unblocked, or change another SMTP look. What kind of machine did you try on? Virtual hosting? Own local?

That's right, the computer room sealed the port. Or your firewall will not open the channel properly.

It should be a Linux-to-case-sensitive issue. You can change it, but you can't get the mail, okay?
