I know for shore, that the config file was filled with correct data, and the database was made from downloaded sql files correctly.
I done some debugging.
To start the mail client, I needed to escape the check mail line
in AjaxMail.inc (line 68,$this->checkMail();), and because I found the JSON.php file wrong (the class Services_JSON is missing), I replaced it with file downloaded from the http://pear.php.net/pepr/pepr-proposal-show.php?id=198
Send mail option started to work but after sending the mail it stopped. I found some errors in the AjaxMail.js
Line 104: this.info = vInfo.parseJSON();
replaced with: this.info = JSON.parse(vInfo);
Line 117: this.message = vMessage.parseJSON();
replaced with: this.message = JSON.parse(vMessage);
Line 625: var oResponse = sData.parseJSON();
replace with: var oResponse = JSON.parse(sData);
After replacing the JSON.php file and correcting those lines, the mail client sent the mail and didn't stop after it.
Still, the check mail action fails on $this->checkMail() line and stops the mail client totally. Somewhere in the pop3.class.php is the problem, but I didn't investigate it.
To see how the original files downloaded from Wrox works, follow the link:
Also, I downloaded the AjaxMail from http://sourceforge.net/projects/ajaxmail/
, it's fails to work too. I found errors in this version too.
English is not my native language. I hope that this lines clearly represents the problem.
