BCC not concealing emails

I just sent an email with all the email addresses in the BCC field, which should have hidden all the email addresses from recipients.

But I received an email from one of the recipients saying that they could see the whole email list. I checked my sent mail and indeed all the email addresses were in the BCC field.

This is really troubling as I often need to send BCC emails. Why would this have happened? And how can I prevent it from happening again?

Thanks so much.

Perhaps you could enlighten everyone who reads your question on how you 'fixed' it.
