Thank you so much for your help, I really appreciate it, wouldn't have known how to log that request otherwise. Hoping it doesn't happen again but I'll remember this for if it does! Re: Virgin SMTP not accepting outgoing Virgin email Thank you again! OK I did that and I got the following: < 421 csmtp6-prd-nl1-vmo.edge.unified.services csmtp6-prd-nl1-vmo.edge.unified.services Virgin Media has blocked your connecting IP xxxx Too many bad emails have been sent. Visit https://netreport.virginmedia.com/netreport Section: Email Sending Errors to request delisting * Got unexpected smtp-server response: 421 Since the problem first started happening I have reset passwords, and know they are correct as they are working when I use 4G. Should I visit that website as suggested, is this likely to help? Thanks again! Re: Virgin SMTP not accepting outgoing Virgin email Sorry, I am new to this forum - I clicked Helpful Answer as it was helpful, but it has not actually resolved the problem as I still can't send email from home wifi, but it is now showing as Accepted Solution. So any other advice would be gratefully received! Re: Virgin SMTP not accepting outgoing Virgin email Thank you very much for your response - my IP address appears to be on the PBL but no other one. Could this still be the reason VM are blocking it and how can I change this if so? Virgin SMTP not accepting outgoing Virgin email I have virgin email (blueyonder addresses) and virgin media broadband/wifi. As of this morning, I'm unable to send any emails from my home using apps accessing home broadband - getting messages about failure to connect to outgoing smtp server. This is for all my devices - iPhones and Desktops. However, I can send email successfully via 4G if I turn off home wifi, so it seems a problem with Virgin SMTP server not accepting emails sent from apps on my home Wifi connection. This is the case for 3 different user email addresses, all have checked or changed passwords and settings, so it is definitely not a problem with passwords. Any ideas how I can correct this? Solved
