How to configure SMTP AUTH (TLS) with Outlook Express

[KevinH]

See the dialogs attached.

After configuration, I can receive emails using outlook express. But when I tried to send email out, I got this error:


The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was 'jgao@optonline.net'. Subject 'Test', Account: 'qa.cirrata.net', Server: 'qa.cirrata.net', Protocol: SMTP, Server Response: '504 <xnet>: Helo command rejected: need fully-qualified hostname', Port: 25, Secure(SSL): No, Server Error: 504, Error Number: 0x800CCC79

Your help appreciated.

You'll need to allow the option for non-fully qualified helo domains. You can do this on the MTA tab in the admin UI. Remember to run postfix reload after you make the change.

Dear All,

I am running 4.0.5_GA_518.UBUNTU6.
Everything is working fine except the performance issues of SMTP-Auth that always annoys people. It causes mail clients such as Outlook Express to always prompt when the traffic to Zimbra's Postfix is quite high.

Please advise what I should do to tune or anything to solve the issue?

Thanks & Regards,
Anggiat

Can you elaborate? This does not make sense
I have been trying to make outlook work for days so it can send mail
I search everything but cannot find a solution.
I want to use outlook as the client.

I get the same error
554<memmomaster@gmail.com>: Relay access denied


PLEASE HELP!!!!!

From the Wiki this is what i read
"Setting the new value
To add hosts, you'll need to add to the existing value you just fetched:

su - zimbra
zmprov ms `zmhostname` zimbraMtaMyNetworks "127.0.0.0/8 10.1.0.0/16 a.b.c.0/24 w.x.y.z/32"

I am not sure how to configure my MTA
This is what I have now after doing the following command...

su - zimbra
postconf -d mynetworks

127.0.0.0/8 222.255.22.168/29

my domain name is chiuyi.vn and fixed IP is 222.255.22.172
The wiki instructions is not specific so can anyone tell me how to fill in the rest?
What else should I put in for the "Relay MTA for external delivery"?

"Relay MTA for external delivery" will be used if you are relaying all of your outbound mails to another server/gateway etc.
If your topology doesn't have one, then it should be left blank!

okay, my dear, how to avoid the relay access denied message from when I send via mail client?

This worked when i recreated your issue
Go under the General Information tab & uncheck "This server is a reverse proxy lookup target"
Then go to the POP tab & then check "Enable clear text login"
& on the MTA Tab uncheck the "TLS authentication only"
That made the client relay the mail.
