I have setup Email notification using SMTP service provided by GoDaddy. I can send email notifications using this SMTP service and can receive email notifications from Ignition GW, however I am not able to see any emails in the sent item folder which sent by Ignition using SMTP profile.
Is there any settings which will save the emails sent by Ignition will save to sent Items? Previously I was using Gmail for same gateway, and that time I can see all notification in the Gmail's sent Item.
Mail user agents are normally responsible for placing a copy of a message in a "Sent" folder, via the IMAP or POP protocols. Ignition is not an MUA, just a mail transport user, so that isn't going to happen. Google just happens to have its transport configured to perform that copy.
You will need to configure GoDaddy to do it, if it can. If you run your own mail server, most SMTP Mail Transport Agents (aka MTAs, like Postfix, Exim, Sendmail, etc) have configuration recipes to do so. The recipes are very dependent on how the MTA and the associated IMAP/POP servers work together, and typically require them to be co-located.
