SMTP Authentication

[sefs]

Usually when I set up email from a share hosting provider ... the email side of things requires that I set SMTP Authentication on before mail can be sent or there is an error.

I would like to do this as well with zimbra.

I have a client sitting on the local network, and one sitting on a network in another location. I am trying to send mail from me@fshzimbra.lan to admin@fshzimbra.lan.

I am using thunderbird.

1/
When I send from client on same network I get below message

"Sending of message failed.
An error occurred sending mail: Unable to authenticate to SMTP server mail.fshzimbra.lan. It does not support authentication (SMTP-AUTH) but you have chosen to use authentication. Uncheck 'Use name and password' for that server or contact your service provider."


2/
When I send from client on external network it does ot mater if smtp auth is on in client or not the mail is sent

What I want is smtp auth enabled on the server just like how it would be if i purchased hosting from a 3rd party.

How can i achieve this? Thanks.

Hi all,\
Are you using port 465 for the smtp authentication?
Try this im master.conf.in file.
465 inet n - n - - smtpd
-o smtpd_tls_wrappermode=yes -o smtpd_sasl_auth_enable=yes
-o smtpd_client_restrictions=permit_sasl_authenticate d,reject

FYI>>465 with athentication
