[swinog] bluewin mail feature

Hoi Zaeme,

occasionally we get mail bounces from bluewin that look like this:

Jul 6 13:17:31 xxxx postfix/smtp[30166]: xxxx: to=x@bluewin.ch, relay=mxbw.bluewin.ch[195.186.99.50]:25, delay=2, delays=0.02/0/0.05/2, dsn=5.0.0, status=bounced (host mxbw.bluewin.ch[195.186.99.50] said: 551 551 x@bluewin.ch Account administratively disabled. Please try later (in reply to RCPT TO command))

the bounces seem to be consistanly linked with the same accounts anmd trying later does not help ... the message remains the same and no mail gets through ...

is this a bluewin feature ? anything the user can configure ? anti spam feature ?

cheers tobi
