About half the emails sent from my application have been returning an error and not sent:
(Today, about 60 of 120 failed) Error Text: "Specified socket descriptor is not valid for this application [10038]" I've not got a clue what this means Some go through, some don't. "Usually", it's the same email addresses that fail, but not always. These email typically have 2 pdf attachments Windows 2012 Server 4D Server 16r6 Using "SMTP_Send" Internet Commands Port 587 Authenticated User/Password Any help, most appreciated.
