SMTP E-Mail Pipe broken error

[eluser]Alexandru[/eluser]
Dear Codeigniters,
I try to send some E-Mails through SMTP and sometimes it works well, sometimes it drops an notice error without sending the mail.

Code:

Severity: Notice

Message: fwrite() [function.fwrite]: send of 1286 bytes failed with errno=32 Broken pipe

Filename: libraries/Email.php

Line Number: 1856

Is what I get. Does anybody know what to do to solve this or how to track the problem?

Broken pipe means an interruption in your connection that was, in this case, opened by fsockopen. I guess your script is (a) to slow in running its code or (b) the remote server cuts connections after a certain amount of time and your script unfortunately exceeds that limit.
