I discovered this issue in their DNS with respect to SPF: ;; ANSWER SECTION: lymanworldwide.com. 1800 IN TXT "v=spf1 include:netcore.co.in -all" lymanworldwide.com. 1800 IN TXT "v=spf1 include:spf.protection.outlook.com -all" But it does not appear to me that the connection is getting to the point where SPF is considered. -- *** e-Mail is NOT a SECURE channel *** Do NOT transmit sensitive data via e-Mail Do NOT open attachments nor follow links sent by e-Mail James B.
