Message sending problem

When trying to send an email with any political content I get the message below:

[SMTP]Cannot send message (Email body not accepted due to the following reason:
"5.7.1 [VO-1] Message blocked due to spam content in the message.

I can log into my ISP account and send the email. None of the posted solutions help. It actually appears as if eM Client is censoring political content. All other types of content go through fine.

This is a message from your email provider’s server. They won’t accept the content in your message.

You will need to contact them for assistance, and they will be able to tell you what they object to.

As I mentioned, if I log into my email provider online I can see the message and forward or send a new message with no problem. If it were their server why wouldn’t it dislike the same message when sent from their website?

Webmail doesn’t use SMTP to connect to the server, so won’t have the same restrictions your email provider places on email applications.

You will need to contact your email provider and ask them why they won’t accept the message. Only they can answer that.
