Postfix error: 500 No Host option provided

I am currently testing a new RT installation. Currently I am able to send,
via telnet, email from the RT address rt@host.example.com to an internal
address (user@example.com).

You appear to have asked variants on this question a few times.
In each case, a mailing list user asked you for information needed to
help you.

How are you invoking rt-mailgate, from an aliases file?
Show the alias file, with all the options you are passing to
rt-mailgate.

Have you read your apache error log? Since you’re getting a 500
error, and that’s an HTPT status code, I’d look there.

Apologies. I have not been seeing the responses. Checking my spam folder
did not turn up the emails either.

My aliases file contains two entries. One for rt: and the other for
rt-comment:

rt: “|/opt/rt4/bin/rt-mailgate --queue general --action
correspond --url http://host.example.com”
rt-comment: “|/opt/rt4/bin/rt-mailgate --queue general --action comment
–url http://host.example.com”

The web logs don’t mention anything about this.

From the server itself what if execute the following while in an SSH
session (obviously replacing the host.example.com with the correct fqdn of
RT):

curl http://host.example.com

What do you get back? If you get a 500 error back from that your problem
is not RT related (yet).On 16 January 2014 12:30, Mathew Snyder mathew.snyder@gmail.com wrote:

Great…

After sending multiple emails due to not seeing responses and then finally
getting one, I’ve discovered that the aliases file was malformed. I didn’t
actually have “–url http://host.example.com”. Instead I had “–url http:
host.example.com”

/facepalm

I guess that’s why pasting what you actually have instead of what is in the
documentation is important in a problem description.On 16 January 2014 12:40, Mathew Snyder mathew.snyder@gmail.com wrote:
