Mail channel is marking outgoing emails as spam
My email hosting provider is is using mailchannels spam filter for outbound email, and after I switched from K9 to Thunderbird (Android) all my outgoing emails are being marked as spam and blocked. I have a ongoing case logged with them but checking if any one has any advice or has similar issues?
Note k9 works fine, I'm guessing they are confused with headers from PC vs mobile version
