<div>Hi Michael,</div>
<div><br>
</div>
<div>Sending to the list through my server works fine. It is just that I don't receive these mails on Postfix. I received them on Sendmail. No harm done as I still receive them on my workmail though.</div>
<div>It is curious..... 😁</div>
<div>Regards,</div>
<div><br>

<br>
That happens when your BlueOnyx relays through your IPS's MTA in order <br>
to send email to the BlueOnyx list server?<br>
<br>
The error message indicates that your end couldn't find a common ground <br>
when negotiating with the BlueOnyx server about which SSL protocol and <br>
ciphers to use.<br>
<br>
The listserver is a 5209R running Sendmail and I'm about to upgrade it <br>
to a 5210R using Postfix this weekend. Still: The ciphers and protocols <br>
it uses are standard and it has common grounds in that regards with <br>
pretty much anything. The only thing it can't do is TLSv1.3.<br>
<br>
I'm wondering if your ISP is using an even older antiquity MTA which <br>
can't handle modern or semi-modern TLS ciphers.<br>
<br>

With best regards<br>
