I'm sorry, but it appears that you do not have an active maintenance or support agreement with us. Because of this, your message has been moved into a low priority queue where we will try to answer it over the next several 5-10 working days. Note that for out-of-maintenance support we cannot go into detail or spend a lot of time on the problem.<br /> <br /> If you need a more urgent response, or the problem is complex, you should take out a maintenance or priority support agreement.<br /> <br /> An annual maintenance agreement costs 25% of the full licence fee and includes email technical support and software version upgrades. All new licences include 1 year of maintenance.(Maintenance runs from the previous expiry of your maintenance, so if it expired over a year ago you may be better taking out priority support).<br /> <br /> An annual priority support agreement costs 50% of the full licence fee and includes priority email technical support, and telephone and remote support during UK office hours. This can be taken out even if maintenance has lapsed.<br /> <br /> You can buy maintenance or support agreements online at <a href="https://www.pscs.co.uk/helpdesk/purchase.php">https://www.pscs.co.uk/helpdesk/purchase.php</a><br /> <br /> Alternatively you can use our free online self-service resources:<br /> - our knowledgebase at <a href="https://wiki.pscs.co.uk">https://wiki.pscs.co.uk</a><br /> - our support portal, including forum at <a href="https://helpdesk.pscs.co.uk/">https://helpdesk.pscs.co.uk/</a><br /> <br /> Solutions to many questions and problems can be found by searching the above resources. For instance, if you have received an error message from VPOP3, try searching for the error message text or subject of the error message email. About 80% of the support queries we receive have already been answered in our knowledgebase.

Hi Matt,<br /> <br /> &gt; I am getting this error in my logs for an email address we are having trouble sending to. Any suggestions on what is going on here would be great.

Unfortunate that means that most of what I'm going to write next is a bit technical, because encryption is.<br /> <br /> The code 336122170 means &quot;Error:1408D13A:SSL routines:SSL3_GET_KEY_EXCHANGE:unable to find ecdh parameters&quot;.<br /> <br /> That means that VPOP3 and the remote mail server cannot negotiate ECDH (Elliptic Curve Diffie Hellman) parameters that both VPOP3 and the remote server are happy with. Usually that means that the remote server has a bad ECDH configuration because the sending part of VPOP3 has no requirements for what type of ECDH parameters are used and will accept whatever the server provides.<br /> <br /> If the remote server configuration can't be fixed, then you would need to write a custom Lua script for VPOP3 to tell VPOP3 not use use SSL encryption when communicating with that remote server. You would need to write a 'ServerDetails' function in the mxout.lua script - see here for details: <a href="https://wiki.pscs.co.uk/reference:lua_smtp_mx_control">https://wiki.pscs.co.uk/reference:lua_smtp_mx_control</a><br /> <br /> <br /> Regards<br /> <br /> Paul<br /> <br /> ---<br /> To reply to this message, just reply to this email.<br />
