The content of the messages are always going to look somewhat suspicious. Given that, the recipients probably need some assurance that it's coming "from" you, assuming your domain is in the From: field. (If it isn't, none of this is your problem and you need to push back on Reflexion). That may make scoring-spam filters (which it sounds like you're hitting at optimum.net) less suspicious of the mail. (Or it may not, none of this is a magic bullet). Check that your customer has include:reflexion.net in their SPF record, and that it's otherwise a valid record. Have reflexion DKIM sign the mail on behalf of your customer. If they do, and the mail is still being blocked by content filters then it's Reflexion's problem rather than yours or your customers. It's also possible that Reflexion is just sending terribly structured mail that "looks like" spam - not unusual amongst companies who build their own mail software - but I'd need to see the mail they're sending before judging that. If you've done what the vendor suggests, and there's nothing you can modify to affect delivery and mail isn't being delivered then there's nothing you can do about it other than pressure the vendor (or move to a different vendor, or use a different approach for sending encrypted messages).
