<p>Fixed.</p><p>The issue was with an autocomplete entry. Autocomplete was placing the alias in the To: field when clicking Reply. The solution was to delete the autocomplete entry from Outlook's list.</p>

<div>Hi</div><div> </div><div>We saw an issue last week where a couple of people using Outlook who replied to a message sent from our domain were getting non-delivery responses. The message was addressed to the recipients using a distribution list.</div><div> </div><div>We are using the latest versions of Pegasus Mail and Mercury/32.</div><div> </div><div>What happened is that when the recipients (we are aware of three who were affected by this) use the Reply function Outlook puts the alias in the To: field. The From: field contains the full address.</div><div> </div><div>For example, the recipient opens my message and my address is shown in the From: field as green.man@mydomain.com. Their mail client will have this listed in their contacts as:</div><div> </div><div>G<span style="font-size: 10pt;">reen Man = green.man@mydomain.com.</span></div><div> </div><div><span style="font-size: 10pt;">When they click reply, Outlook is placing 'Green Man' in the To: field and not green.man@mydomain.com</span></div><div> </div><div>My question is has anyone seen this behaviour before and do you know what may be causing it? I understand this may be an Outlook issue or an issue with their set-up, but I would like to make sure that this was not caused by something at our end.</div><div> </div><div>One of the people who had this issue forwarded me their reply:</div><div> </div><div>From: Green Man [mailto:green.man@mydomain.com] </div><div>Sent: 07 March 2014 16:59</div><div><span style="font-size: 10pt;">To: Green Man</span> </div><div> </div><div>Has anyone seen this before or know what the issue may be, please?</div><div> </div><div>Thanks! </div>
