Hi Ahmed, >From your error msg, it shows that your user cannot connect from external IP to port 25 of your server because they are blocked by RBLSMTP. They will have to use submission port instead.
Please check your server log files and see if there's anything wrong, such as: qq hard reject (DomainKeys verify status: bad format (#5.3.0)) May be you can disable Domainkey for now and see if it's related to your problem. Good Luck. Best regards, Bill On 9/2/07, Ahmed Shareef <[EMAIL PROTECTED]> wrote: > Could somebody help me.
