SMTP Relay Settings

Post by jpurssey » Fri Mar 02, 2018 6:01 pm

I have a Synology NAS on my network. It provides (among other things):
A Mail server and Mail client
Applications such as TikiWiki, Mediawiki, Wordpress etc which try to mail out things such as password reset links and registration confirmations.

The MailServer settings provide for SMTP to be enabled and for an SMTP Relay to be enabled.

The relay setting is
server smpt.nsw.exemail.com.au,
Port 587,
TLS not required,
authentication not required,

The SMTP settings are:
SMTP enabled
Sender name and login name need not be identical
Hostname is a redirection to my fixed IP, Port is 25
SMTP-SSL is Port 465
SMTP-TLS is Port 587

On a search of this forum I saw that optusnet has also been used as a relay, but this did not work either.

Can you advise what settings or method I should use, please.
John

As per the sticky post I have now disabled SMTP Authentication and SMTP-SSL (and SMTP-TLS) but the emails never arrive.

I have now seen the MAILER-DAEMON re[plies. Regardless of the original settings I had or the changes the response is
This is the mail system at host xxxxxxx.diskstation.me.

I'm sorry to have to inform you that your message could not
be delivered to one or more recipients. It's attached below.

For further assistance, please send mail to postmaster.

If you do so, please include this problem report. You can
delete your own text from the attached returned message.

The mail system

<xxxxxxx@yahoo.com.au>: host smtp.nsw.exemail.com.au[220.233.0.8] said: 550
relay not permitted, authentication required (in reply to RCPT TO command)

Since we enabled SMTP auth on our smtp servers, please refer below and have your config accordingly.

With Exetel IP, you can use our smtp server
smtp.[state].exemail.com.au without smtp auth configuration.
port: 25 (default)
SSL/TLS: on (default)

With non-Exetel IPs, or any Exetel IP you want to use smtp auth
couple of things need to configure
server: smtp.[state].exemail.com.au
SMTP authentication: enable
Username: exemail address
password: exemail password
SSL/TLS: on
Port: 587
Authentication Type : MD5

The SSL should be always ON now, no matter it is with Exetel IP or not.

Hi Kavinda,

Thankfully Exetel have now enabled SSL/TLS for email, as I was really concerned about sending plain text email passwords via POP3. So I am wanting to use SSL/TLS for both POP3 and SMTP, to increase security. I have no problems setting up the pop3, but I can't get the SMTP to work.
I have tried every combination in the Thunderbird v60.7, but to no avail, including your recommended settings. (note: no option for MD5 "authentication type" is available in thunderbird). Here are my settings coming from a EXETEL IP address:

Server Name: smtp.nsw.exemail.com.au
Port: 25
Connection Security: SSL/TLS
Authentication method: No Authentication

When I send an email it says "Connected to smtp.nsw.exemail.com.au" but then times out with a message: "Sending of the message failed. smtp.nsw.com.au timed out.".

Looks like I can't configure the SSL/TLS for SMTP. Can you help?

Can you please document what the settings should be. Also could you update your Thunderbird PDF referenced at http://exewiki.exetel.com.au/index.php? ... tup_Guides? The default for all should be SSL/TLS.

Regards

Hi Rasikak,

Thanks for you reply, and I have read, re-read and then re-read again those instruction but to no avail. Thunderbird simply does not allow for the "MD5" and "enable" parameters to be set, although "Connection Security: SSL/TLS" probably translates to "SMTP authentication: enable" . The options for SMTP settings in thunderbird V60.8.0 are:

Server Name: smtp.nsw.exemail.com.au
Port: 587
Connection Security: SSL/TLS (also available for selection are: "STARTTLS" and "None")
Authentication method: "Normal Password" (also available for selection are: "No Authentication", "Normal Password", "Encrypted Password", "Kerberos GSSAPI", "NTLM" and "OAuth2".
UserName: xxxx@exemail.com.au

Note that there is no "MD5" option available. Would it be possible for you to install Thunderbird and attempt to set the parameters yourself to perform a test to see if you can get it to work?

Many thanks,

Thank you for reaching out. the settings which are provided in the page are the generic settings that would need to configure Exemail in any client version. MD5 setting mostly apply with iOS devices. Please refer the Authentication method as Encrypted Password and check the service.

Thanks for the quick response. I have set " Authentication method as Encrypted Password " but still no emails can be sent no matter what I try when "SSL/TSL enabled" is enabled. Also thunderbird does not prompt for a password when sending - so I assume it is using the pop3 password.

Note that I can receive email via pop3 and SSl/TSL enabled, and send email with issue when using port 25 and "Connection Security:=None".

Can you try installing thunderbird and seeing if your method works for you?

Thanks.
