            All _ I would appreciate any help with an issue. I am a moderator with admin rights on a local community forum - Joomla/Kunena. When members post in certain topic sections they have started to receive the following error message: 'Fatal Error: Cannot redeclare xmail() in libraries/phpmailer/phpmailer.php on line 1 The error was detected in the Libraries.'

            I have consulted Kunena forum but they suggest I try here as it appears to be an xmail issue. Does anyone have any advice? I would be very grateful.

            Re: Multiple domains on the same IP address

            Same thing here, the emails mostly bounce with 417 temporary delivery error.
            I think it has something to do with the primary domain for SMTP.
            Is there any way to get help on proper configuration for multiple domains?

            multiple domains on one IP

            I am trying to setup several different domains on one Xmail server all with the same IP address.

            It has been having problems with relay and seems to come of an invalid PTR record. There is only one PTR record to the root domain, but many other emails get bounced back from the rest of the domains.

            How should I be setting it up?

            Thanks a lot.

            Re: Windows XP configuration
            Are you trying to send mail (SMTP) or get mail (POP3), while getting the password retry?
            How did you configure your server? Manually, or using the CtrlClnt tool?
