Re: [otrs] fully-qualified hostname issue

"Out the box" OTRS will be using sendmail (which in turn will pass it to postfix). Check /etc/postfix/main.cf and look for the value myhostname or myorigin and see what the values are. myorigin is usually configured to point to /etc/mailname which is a text file that will contain the FQDN of your server which postfix uses when it performs HELO (don't forget to restart postfix after making any changes).

Not entirely sure, but I used the standard Ubuntu installation, so it would be Postfix which SMTP I guess.

How is OTRS configured to deliver email? Sendmail or SMTP?

Hi All

I am running OTRS version 3.2.2 on Ubuntu 12.04 Server.

I have an issue with mails going out to some client. I suspect their mailers are doing a DNS lookup or verifying for a valid or FSDN from/return address.

When I mail the clients from my own mail client (outlook or thunderbird) it works fine.

When I respond to the client from OTRS the mails are rejected by the remote mailer. See error below:

---------------------------------------------------------------------- -------------------------------------- : host anubis.se.axis.com[195.60.68.12] said: 504 5.5.2 <Ubuntu-OTRS>: Helo command rejected: need fully-qualified hostname (in reply to RCPT TO command)

---------------------------------------------------------------------- ------------------------------------

I tried changing the actual Ubuntu host name to a FQDN but it still does not work.

I tried looked in the admin - framework settings for any way of sending mails out with ha FSQN but I cannot find any settings there.

Our mailer has a valid MX record, so I am not sure where to start looking.

If any person can direct me in the right direction I would highly appreciate it.

Kind Regards Jason
