Extension disallowed

Hello, how are you?
It doesn’t let me attach emails that I put to forward as an attachment, giving me an error “.eml as disallowed extension”.
I have the latest version of em Client, and I don’t see any option to add this extension.
Does this error have a solution other than first saving the email as a file and then attaching it? Can an email from em Client really be attached to another email?

I have the same issue. Sending email with an .eml file attached to it, failed with error: “email body not accepted due to the following reason ‘attached file has disallowed extension’”

I carn’t find anything on the forum about that.

Suggest if either of you have a current active paid Pro or Personal version to go to the VIP support page and login and lodge a support ticket for help on that.
