I am finding it difficut to get the rabbitmq-email and postfix to get working.

sam@domain.com: mail for domain.com loops back to myself

Can you please post

samjadmooppan commented 8 years ago

Thanks Michael,

  1. I am working on an application which will push an email to RabbitMQ using Postfix and rabbitmq-email. The data will then be fetched from rabbitMQ queue and pushed to a database.
  2. There is nothing on the rabbitmq logs. My configuration for rabbitmq-email is as follows

{rabbitmq_email, [ {server_config, [ [{port, 25}, {protocol, tcp}, {domain, "app.mydomain.com"}, {address,{0,0,0,0}}] ]}, {server_auth, rabbitmq}, {server_starttls, true}, {email_domains, [{<<"app.mydomain.com">>, {<<"/">>, <<"email-in">>}} ]}, {email_queues, [{{<<"/">>, <<"email-out">>}, <<"app.mydomain.com">>} ]}, {client_sender, "arun@app.mydomain.com"}, {client_config, [ {relay, "app.mydomain.com"} ]} ]}

  1. The postfix configuration main.cf is as follows

  1. The postfix transport file is

app.mydomain.com smtp:app.mydomain.com:25

  1. When i try to send a mail to arun@app.mydomain.com , the postfix logs shows the following

Jun 19 14:28:56 zimbra postfix/smtpd[2453]: connect from server.supportlobby.com[158.69.11.64] Jun 19 14:28:56 zimbra postfix/smtpd[2453]: 1E549C1BEB: client=server.supportlobby.com[158.69.11.64] Jun 19 14:28:56 zimbra postfix/cleanup[2458]: 1E549C1BEB: message-id=c42fe5b1-ab74-fcec-82a5-3598d7b5ffb1@activelobby.net Jun 19 14:28:56 zimbra postfix/qmgr[2445]: 1E549C1BEB: from=sam@activelobby.net, size=2178, nrcpt=1 (queue active) Jun 19 14:28:56 zimbra postfix/smtp[2459]: 1E549C1BEB: to=arun@app.mydomain.com, relay=none, delay=0.03, delays=0.03/0/0/0, dsn=5.4.6, status=bounced (mail for app.mydomain.com loops back to myself) Jun 19 14:28:56 zimbra postfix/cleanup[2458]: 3344FC1BEC: message-id=20160619142856.3344FC1BEC@app.mydomain.com Jun 19 14:28:56 zimbra postfix/smtpd[2453]: disconnect from server.supportlobby.com[xx.xx.xx.xx] Jun 19 14:28:56 zimbra postfix/bounce[2460]: 1E549C1BEB: sender non-delivery notification: 3344FC1BEC Jun 19 14:28:56 zimbra postfix/qmgr[2445]: 3344FC1BEC: from=<>, size=4084, nrcpt=1 (queue active) Jun 19 14:28:56 zimbra postfix/qmgr[2445]: 1E549C1BEB: removed Jun 19 14:28:56 zimbra postfix/smtp[2463]: 3344FC1BEC: to=sam@activelobby.net, relay=activelobby.net[xx.xx.xx.xx]:25, delay=0.41, delays=0.04/0.01/0.14/0.21, dsn=2.0.0, status=sent (250 OK id=1bEdie-0006yd-FO) Jun 19 14:28:56 zimbra postfix/qmgr[2445]: 3344FC1BEC: removed

  1. The bounce message is
    The mail system

arun@app.mydomain.com: mail for app.mydomain.com loops back to myself

gotthardp commented 8 years ago

It think the postfix is misconfigured. By doing this

myhostname = app.mydomain.com
mydestination = localhost.$mydomain, localhost, $myhostname
relay_domains = $mydestination, gmail.com, app.mydomain.com, activelobby.net, server.supportlobby.com

you essentially say that mail for app.mydomain.com should be delivered to the postfix server and at the same time that it shall be relayed to another server, whose address points again to the same postfix server (itself), which is the error you are getting.

Please add the domain that corresponds to the rabbitmq-email instance only to the relay_domains.

Thanks Guys,

Got it working. I have one more clarification. I am looking to pool multiple mail domains . For eg : app1.mydomain.com, app2.mydomain.com ....app'n'.mydomian.com to rabbitmq email.

The rabbitmq shows that the messages are queued , however its not there in the configured queue.

` =INFO REPORT==== 23-Jun-2016::05:06:31 === text/plain message from sam@activelobby.net to [<"arun@app2.mydomain.com">] queued as 75525d3b83b21b1bc8f4390471199dae

Please note that incoming e-mails are sent to the AMQP Exchange you configured in email_domains. If this exchange is not bound to any queue, the AMQP message gets discarded. Couldn't this be the case?

samjadmooppan commented 8 years ago

I had the exchange type set as topic. Worked once i configured the queue correctly . Thanks again :) . All issues solved :)

Hi gotthardp

Thank you for great help. Now how do i get rabbitMQ to send back mail to my postfix server sitting somewhere, it seems sending to rabbitMQ looks great. How do you route back mail to postfix server.

gotthardp commented 7 years ago

Hello. The outgoing mail is sent to a SMTP server, which then delivers it to Postfix or any other target recipient.

michaelklishin commented 7 years ago

AMQP 0-9-1 to email flow is decently documented:

tofaramac commented 7 years ago

Thank you, so if i have more than one domain i want rabbitMQ to handle i should define them on the rabbitMQ server under RabbitMQ Configuration as this server wont accept mail for unknown recipients ?

i have more than one domain for my Apps , i have sub-domains as well i want rabbitMQ to handle mail for
