Ehlo Command Not Recognized12,600 Views Last Modified: 2013-11-30 Hi guys, Confused here. Trying to do some smtp tests on our centos 5.3 mail gateway (postfix). Tried to do some smtp tests via a telnet session, and I cant get any of the commands work. Ive tried ehlo, hello, helo, and none of these works. All say "error: command not recognised" Do i need to install or enable ehlo command not found ubuntu something to allow this work? 0 Question by:Network_Padawan Facebook Twitter LinkedIn Google LVL 23 Best Solution byMysidia The SMTP RFC specifies exactly what syntax is allowed for the HELO command, and when keying it manually, it is easy to make a syntax error.

Unfortunately, when doing so, both our primary mail server and the local Mail service on the server throw a "502 5.5.2 Error: command not recognized" error when attempting to send the test message. Both our primary http://serverfault.com/questions/268267/why-does-postfix-mail-server-throw-error-502-when-testing-email-from-drobo-dashb 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: connect from localhost[127.0.0.1] May 10 13:32:58 eeg postfix/smtpd: match_hostname: localhost ~? 127.0.0.0/8 May 10 13:32:58 eeg postfix/smtpd: match_hostaddr: 127.0.0.1 ~? 127.0.0.0/8 May 10 13:32:58 eeg postfix/smtpd: > localhost[127.0.0.1]: 220 host.domain.tld ESMTP Postfix May 10 13:32:58 eeg postfix/smtpd: watchdog_pat: 0x109998 May 10 13:32:58 eeg postfix/smtpd: vstream_fflush_some: fd 9 flush 36 May 10 13:32:58 eeg postfix/smtpd: vstream_buf_get_ready: fd 9 got 23 May 10 13:32:58 eeg postfix/smtpd: < localhost[127.0.0.1]: EHLO host.domain.tld May 10 13:32:58 eeg postfix/smtpd: > localhost[127.0.0.1]: 250-host.

Becuase of this my mails are not flowing. All other commands (Helo, Ehlo) gives me response as unrecognized. Port 25 is opened. Has any one seen this issue before.

Becuase of this my mails are not flowing. The banner looks suspiciously like what you'd get if you were using a Cisco PIX firewall with their Mail Guard feature enabled. Turn it off.
