i recently had a barracuada tech guy visit me as far as i understand all users will connect to barracuda appliance -- it monitors both mx (incoming mails) and also outgoing emails (authenticated senders) for outgoing spam.
incoming emails will be filtered and sent to the qmt box and forward it to qmt box qmt box smtp service will accept connections only from barracuda. pop3 / imap users will download emails from qmt box but send via barracuda server. rajesh ----- Original Message ----- From: Eric Shubert [mailto:[email protected]] To: [email protected] Sent: Sat, 06 Dec 2014 11:34:40 -0700 Subject: [qmailtoaster] Re: smtp auth I'm not sure you want to do this. This would make barracuda an open relay, allowing it to send to *any* domain, not just the ones local to your QMT. Are your clients submitting to barracuda or QMT?? I was thinking that barracuda was handling only MX (incoming) traffic. What's the point of having barracuda handling submissions? -- -Eric 'shubes' On 12/06/2014 03:47 AM, Rajesh M wrote: > dave > > port 587 (qmailtoaster submission port) is configured to use smtp > authentication by default > > pl see /var/qmail/supervise/submission/run > > to disable smtp authentication for barracuda ip pl try this > > nano /etc/tcprules.d/tcp.smtp > > add the line below to the file on top, where 1.1.1.1 is your barracuda ip > > 1.1.1.1:allow,RELAYCLIENT="",CHKUSER_START="NONE" > > # qmailtctlcdb > > there is no need to restart qmail > > rajesh > > > ----- Original Message ----- > From: SYS [mailto:[email protected]] > To: [email protected] > Sent: Fri, 05 Dec 2014 11:46:42 -0700 > Subject: [qmailtoaster] smtp auth > > Hi guys, been a while, out of country on business. > However when I got back , I find the the company bought a Barracuda to > help supposedly with spam catching.
