2) I assume the smtp status code (500) means the problem is on my side. Correct or not ?
No. It's their mail server that's broken.
3) What is causing the problem ?
Their broken mail server.
Connected to mail.folkbildning.net. Escape character is '^]'. 220 mail.folkbildning.net FirstClass ESMTP Mail Server v8.0 ready EHLO default 250-mail.folkbildning.net Hello default (216.254.115.84), pleased to meet you 250-PIPELINING 250-AUTH=CRAM-MD5 LOGIN PLAIN 250-AUTH CRAM-MD5 LOGIN PLAIN 250-STARTTLS 250 8BITMIME
Right there, in plain sight, their mail server claims support for the STARTTLS command. However:
STARTTLS 500 Command not recognized: STARTTLS
You can't possibly know what else could be screwed up with this broken mail server, so I wouldn't waste any more time on it, and write it off as a lost cause.
