Recently I’ve had problems sending e-mail messages to some recipients. Turns out most of these (all?) use GoDaddy. Today I entered a new Lead into my CRM. My workflow automatically sent the Lead my follow up e-mail. It bounced! The Undeliverable message included this information:
smtp.secureserver.net #<smtp.secureserver.net #5.0.0 SMTP; 554 The message was rejected because it contains prohibited virus or spam content> #SMTP#
My CRM template includes links to my logos so I deleted them and tried again. Once again the message bounced with the same reason. So I tried turning the message into plain text. This time it went right through! After removing the logo links, I still had some formatting in the message, fonts and such. Going to plain text removed the formatting, resulting in an ugly message. But a message that was accepted none the less.
