B2B-PrivaSphere as there is no ticketing system I could find, I will write this here. We are trying to transmit an email to a hispeed.ch user. Sadly the answer we are getting for en entire day is: host mxin2-hispeed-ch.edge.unified.services[94.169.2.18] said: 421 4.2.0 MXIN613 Greylisting wait period active. Please retry later
Daniele_Sunrise B2B-PrivaSphere Welcome to the community! The IP seems to be blacklisted at Spamhaus. Since I don’t know which lists we use, please contact our Abuse Team at abuse@upc.ch. Greetings Daniele
B2B-PrivaSphere That is your IP, so this sounds more like a second problem you have Host Information for “94.169.2.18”: IP address: 94.169.2.18 Host name: mxin1-hispeed-ch.edge.unified.services Domain name: unified.services
Daniele_Sunrise B2B-PrivaSphere Oh, then this was deliberately entered in RBL’s so that you can’t send spam without having an account with Hispeed. May we still ask you to contact our Abuse Team and send the full header when contacting us, where the whole mailtrace is visible including error messages? Greetings Daniele
