Smtp Data Command Not Recognized
The best answers are voted up and rise to the top Why does postfix mail server throw error 502 when testing email from Drobo Dashboard? up vote 0 down vote favorite I'm configuring a Drobo on a Mac OS X 10.5 Leopard Server file server and am trying to configure email notifications. Unfortunately, when doing so, both our primary mail server and the local Mail service telnet smtp on the server throw a "502 5.5.2 Error: command not recognized" error when attempting to send the test message. Both our primary mail server and the local Mail service on the file server are Mac OS X 10.5 Leopard Server and so are postfix-based. The primary mail server is set to allow relaying from the local network and the local Mail service is set to only allow relaying from 127.0.0.0/8 and it's IP address and to relay through our primary mail server. This has all worked well for years until now. Drobo Dashboard's Email Settings cannot send through either the primary mail server or localhost without authentication without getting the aforementioned error, although all our other scripts on the server continue to send email normally. I've set debug_peer_level = 3 & debug_peer_list = 127.0.0.1 in /etc/postfix/main.cf on the file server. When attempting to send the test message from Drobo Dashboard, I get the following debug info in /var/log/mail.log: May 10 13:32:58 eeg postfix/smtpd[7320]: connect from localhost[127.0.0.1] May 10 13:32:58 eeg postfix/smtpd[7320]: match_hostname: localhost ~? 127.0.0.0/8 May 10 13:32:58 eeg postfix/smtpd[7320]: match_hostaddr: 127.0.0.1 ~? 127.0.0.0/8 May 10 13:32:58 eeg postfix/smtpd[7320]: > localhost[127.0.0.1]: 220 host.domain.tld ES

Another thought is to check your IP settings of the SMTP server.If those do not work, please consult with online support (sig link) **Franklin is not available** **Please do not Private Message me for support questions; leave it on the forum so all members
