Hi all, New to xwiki and trying to gather all the available support resources. While trying to subscribe xwiki-announce email list I got the following error message... ---- The original message was received at Wed, 28 Feb 2007 20:37:51 +0100 (CET) from 231.Red-80-34-100.staticIP.rima-tde.net [80.34.100.231] ----- The following addresses had permanent fatal errors ----- &lt;xwiki-announce-subscribe(a)objectweb.org&gt; (reason: 550 Unknown local part xwiki-announce-subscribe in &lt;xwiki-announce-subscribe(a)objectweb.org&gt;) ----- Transcript of session follows ----- ... while talking to cvs.objectweb.org.: <<< 550 Unknown local part xwiki-announce-subscribe in &lt;xwiki-announce-subscribe(a)objectweb.org&gt; 550 5.1.1 &lt;xwiki-announce-subscribe(a)objectweb.org&gt;rg>... User unknown <<< 503 Valid RCPT TO <recipient> must precede DATA ----- But, when trying to do the same from http://www.objectweb.org/wws/info/xwiki-announces it worked fine. Could this behaviour be a symptom of any problem with the subscription process? HTH, Ricardo -- Ricardo Rodríguez Your XEN ICT Team
