I have a form that calls a sendmail tag to send user-feedback to a specific email-adress. When I try to send mail I always get the error:
Recieved error code 553 from SMTP: 553 ... Domain name required
I know that this error occurs if the user is not allowed to send mail from that host. The SMTP error 553 means that there is a syntactical problem with one of the mail headers, usually an address header.
Your SMTP server tells you that it expects a "Domain name" and there is none. This may be indicative to either: 1. one of your mail headers (To:, From:, ...) is faulty 2. you did not specify any domain name and the SMTP server cannot provide the default domainname due to some configuration problem. Under Unix, the program "hostname -f" provides the default host name. Dieter
