Error when sending SMTP mail with a forwarded mail

Hi all,

i’m trying to forward a mail onto a colleague via an Send SMTP Mail activity

but i’m getting the following message below.

Send SMTP Mail Message: 5.6.0 Invalid message content when handling MIME exception. IMC53

Now i’ve tested it without forwarding the message and it works fine with just a stand subject/body email.

can anyone suggest what might be the problem?

Thank you.

Hey man,
