Hello,
One of my Swiss customer is reporting systematic spam filtering with e-mails
originating from his server to bluewin customers.
I tried to send a request to postmaster(a)bluewin.ch but no answer yet.
I would like to know why e-mails are filtered (I double-checked SMTP config) so
is there someone from the bluewin's postmaster team here ?
Thanks for your answer and sorry for the noise,
Julien Escario
