we are a Shaw business customer and use Shaw email relay ("shawmail.vc.shawcable.net,shawmail.vn.shawcable.net,shawmail.vf.shawcable.net") server with MS Exchange Server on premise
it happened that Shaw blacklist us (Shaw directly not "Spamhaus DBL" or "BARRACUDA" or other lists)
Last time it took 5 hours to to get us of Shaw list (if we not call in it would happen automatically after 6pm (PST)
The blacklisting occurred because of a recipient flagging an email(s) from originating from your IP as spam. There was also some detection of a virus infection accompanying an email, as this was reported twice.
No further details were provided so we didn't had much of a details to investigate (beside a general scan for virus)
BTW Shaw suggest to use webmail in the meantime which is a joke consider we use our own domain (not @shaw.ca)
- How can we ask the first level help-desk on the phone to check if we are SHAW blacklisted? (Does the Shaw helpdesk has info about this)
- Why are we (client who got blacklisted) not notified / informant about this?
- how can we get more details (detail report) why we got blacklisted?
- How fast we can get off the Shaw blacklist?
