      No doubt some idiot has been sending what appears to be spam from the Skyuser account. Have you reported the matter using the Contact form. Contact Us - Sky User - The Unofficial Support Forum for everything Sky!

      Re: hotmail rejecting email sent through smtp sky user account

      Is anybody still having trouble with sending to hotmail accounts? Mine has not been working since Monday as well and I reported it using the form as suggested, presumed it would be sorted by now but have gone to send some invoices this afternoon and both to hotmail accounts have bounced straight back?!
      Any suggestions on anything i can do or is it sit back and wait?

      Thanks

      Jess

      Re: hotmail rejecting email sent through smtp sky user account

      As mentioned in another thread, it looks like someone was spamming through the SyUSer SMTP Server.

      The culprit has been identified and it should take around 7 days to get things back to normal.

      On behalf of Glenn and Ged, please accept our appoligies.

      In the mean time I would urge everyone to double check that their computers have all their protective measures updated and scan their computers with a collection of different AV and Anti-Malware products to ensure that the computers are clean.

      Without going on too much, Linux, Mac, Windows, iOS and Android devices can all get nasties. Sure Windows computers are targeted more often, but the others are too. So please check them all.
