Hi Sanjay, VT Solutions is using an Exchange Server with SMTP as mail.{REDACTED}
There emails are failing and they have mentioned that we need to upgrade TLS.
Is there anything as such from our end that may be causing the failures.

Sanjay, 4:04 PM
Hi Vineshwar, what version are they on?

Vineshwar, 5:29 PM
12.30.0224.GA

Hi Vineshwar, case number?

The mail client we use in V13 uses TLS1.2 by default, I will have to check the version 12.

Can you install 13.2 on their test server and verify?

Bula Team,

We have Upgraded the client to version 13.20.1215.GA as per the case E01756 on 25/01/2021.

We have advised Monica that the Emails are still failing and they need to verify if the SMTP details are correct.

Regards
Vineshwar Prasad

Hello Vineshwar,

As discussed please escalate this to you engineers in Australia, we need to work with them and resolve asap please.

Attached feedback from our email host team

I have tested the mail relay, and if I use a client using TLS 1.0 or TLS 1.1, I get the same error message that you are getting. "authentication failed because the remote party has closed the transmission stream".
I I use the same software, but enure that it is only using TLS 1.2 - I get a successful authentication and the mail is relayed.

Hi Vineshwar, 

LinkSOFT Version 12 uses Dot Net Framework 4.6 which uses TLS 1.2 by default. LinkSOFT 13 uses DOT NET Framework 4.8

You can check which version of DOT Net your installation is using by looking at the web.config. Tag: 

<system.web>
<compilation targetFramework="4.8">

Here is an example of SMTP settings for you to check on site:

<smtp from="Fujitsu Automated Email &lt;Fujitsu-Automated@Fujitsu.com.au&gt;">
    <network host="smtp.office365.com" port="587" enableSsl="true" password="######" userName="NoReply@Fujitsu.com.au" />
</smtp>

If you want, I can connect via teams with you and we can have a look.

Regards
Sanjay

Just FYI - the "From Email address" is important. If using Clients smtp, you have to either leave the Global Configuration for "From Address" blank or use the clients email address.

There is no way to edit the "From Address" once the email is queued in version13.20. I have added the Edit capability in 13.30
