Problems posting to the list lists.mysql.com

[Frank Becker]

Hello,

I tried to response to a posting on the list named in the subject. But 
it is rejected with the following message:

  SMTP error from remote mail server after end of data:
     host lists.mysql.com [213.136.52.31]: 552 spam score exceeded 
threshold (#5.6.1)


Neither this emailaddress is used for spam purposes nor I offered products.

Please, how can I use the list so that I can response to posts?

I read the list via gmane.org

Best regards
Frank Becker
