One of my clients switched from cbeyond to another provider and just like that lost email notifications coming from their ecommerce site. The site is hosted by rackforce. I have access to the plesk panel and shell access to the site. I ought to be able to do command line mail be doing: mail bobm at dottedi.biz <cr> etc... This fails with no obvious error; I tried doing mail -v to see a verbose output but apparently wrong argument. I also made up a very simple php file which when accessed should send me a test message. It also fails, something like: <?php $message = "Email body/contents"; $subject = "Test of php email script"; $to = "bobm at dottedi.biz"; $from = "From: admin at wherever.com"; mail ($to, $subject, $body, $from); ?> No dice of course. Finally within zen-cart itself I found the configuration item for the mail server which was originally set to "mail.west.cbeyond.com" and changed it to: "smtp.integra.net" and the dice remain silent. What are some UNIX/Linux command line tests I can do to determine the root cause? As I have access to Plesk, is there anything in the control panel that needs to be changed that might still be referencing cbeyond? -- Bob Meetin www.dottedi.biz 303-926-0167 Hook up with me on Twitter, Facebook, LinkedIn, Plaxo Pulse and Bebo or catch my blog at www.dottedi.biz/blog.php Standards - you gotta love em - there are so many to choose from!
