I'm just starting to replace a few bits of old code with ZF alternatives, and I'm trying to replace my validation of email addresses. Using the first code example on Zend Framework: Documentation I get the following error:

Sure enough, that file doesn't exist in the copy of ZF I downloaded from Zend Framework: Downloads.

Looking into the ZF code /Zend/Validate/Hostname.php line 325 says:

It looks like there should be one file for each top level domain in that folder, but there are only files for eight of them.

Is the ZF missing something, or am I?

I am also having same problem which fills error logs with errors. I use E_ALL - E_NOTICE to see possible coding errors and warnings, and this error occurs too many times in logs.

Redownload if your unsure and check.
Im unfamiliar with it so can't advise but redownlad with let you know if you accidently deleted.
