I am unable to read messages in base64 encoding.

One company I regularly work with has started sending me emails in base64.  

Content-Transfer-Encoding: base64 Content-Type: text/plain; charset=utf-8

However, the email is not decoded when I receive it.

Is there something I can do to receive the email correctly? 

Hi, can you please export the message you’re having issues with into a .eml file and send it to my email?
You can do that by simply drag and dropping the email onto a new email or to the desktop.

Please send it to my email mcgregor@emclient.com

Thank you,
Paul.

Hi Martin, can you send me the exported message as suggested above?
Also please add a reference link to this forum topic.

Thank you,
Paul.

I sent it.

Another problem: Works notifications of new posts in a forum? I have last email from @getsatisfaction.com 10. july … today not.

Hi Martin, they should work, do you have the “Follow” button active above the post?

Thank you,
Paul. 

Yes, active. I see “unfollow” …

IMO “follow” is automatic, if I submit text in thread.

I’m receiving all the responses from the forum quite fine, can you check if the automatic replies aren’t in your SPAM folder?
I can report the issue to getsatisfaction if needed.

Thank you for reporting this,
Paul.

I’m administrator of small ISP. We are own mailserver. I check log files on server … last message is from 11. july (and it is spam by qSheff :-), but after this - nothing.
Before this - emails coming fine (20 pieces).
