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 mail server command not implemented 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 ESMTP Postfix May 10 13:32:58 eeg postfix/smtpd[7320]: watchdog_pat: 0x109998 May 10 13:32:58 eeg postfix/smtpd[7320]: vstream_fflush_some: fd 9 flush 36 May 10 13:32:58 eeg postfix/smtpd[7320]: vstream_buf_get_ready: fd 9 got 23 May 10 13:32:58 eeg postfix/smtpd[7320]: < localhost[127.0.0.1]: EHLO host.domain.tld May 10 13:32:58 eeg postfix/smtpd[7320]: > localhost[127.0.0.1]: 250-host.domain.tld May 10 13:32:58

I have tested sending to these domains without untangle and it works fine. With untangle, this is what happens when using telnet to port 25 on the recipient mal server (mx823.au.emailfiltering.com): 220 eci-mta-82.emailfiltering.com emfmtad 33 QUIT 502 Command not implemented (4.2.4) I tried turning off some modules, and found that when I have turned off Virus Blocker and Phishing Blocker (both), it works fine: 220 eci-mta-82.emailfiltering.com emfmtad 33 QUIT 221 Bye for now Could anyone explain this or is there a fix for this? Do I need to include any exceptions in phishing or virus blocker for unrestricted/unchanged traffic from the mail server? 10-26-2011,04:05 PM #2 dmorris Untangle Junkie Join Date Nov 2006 Location San Carlos, CA Posts 15,108 hmm... can you paste the text of the whole SMTP conversation? You can add bypass rules if you like to bypass the traffic in question. Attention: Support and help on the Untangle Forums is provided by volunteers and community members like yourself.

But even if I had a more complete conversation this is what happens: HELO [replaced domain name] 250 sy1-mta-82a.au.emailfiltering.com Greetings [ip address] [[ip address]] MAIL FROM: <[user@domain.com]> 250 <<[user@domain.com]> accepted RCPT TO: <
