@amcotech - Did my answer, posted a day prior to Sunnyc7's not answer your question correctly? &nbsp;Either I am going blind or mine clearly states the command is either:<br />
HELO mail.yourdomain.com or<br />
&nbsp;EHLO mail.yourdomain.com &nbsp;<br />

</div>


<div>
I think you said EHLO above @alan<br />

<div>
Sunny - what are your thoughts on this one?<br />
Alan<br />

<div>
Alan Sorry - I have not been on EE for a while.<br />
I am just checking good answer Alerts or 1/2 questions.<br />
<br />
I think points should have been allocated to Alan as he got it first.

<div>
Thanks Sunny - as it stands, the points will be split, which I am happy with.
