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?

Those are the classic signs that VM are blocking VM emails coming from the IP address of your home network. The reason you can send when using mobile data is that in that case the IP address you use will be the one allocated by your mobile provider and so will not be blocked by VM.
The most likely reason for VM blocking your emails is that the IP address of your home VM network is on a Spamhaus blocklist as a sender of spam. There is no suggestion that anyone in your household is sending spam. However, Spamhaus will have detected suspicious traffic coming from your home network over a period of time and that traffic is likely to have been generated by malware on a smart device on your home network.
You can check the status of your IP address by following these steps:
browse to https://whatismyipaddress.com/ and note or copy (Ctrl+C) the IPv4 address
then go to https://check.spamhaus.org/ and paste (Ctrl+P) or type your IPv4 address in to the "Search single IP...." box and click "Lookup"
Your IP address may well be listed on the PBL (Policy Block List). In that case it will be flagged up as an advisory but that is to be expected and is not the reason you cannot send emails from your mail apps.
However, if Spamhaus reports that the IP address is listed on any other blocklists, such as Spamhaus' Exploits Block List (XBL) for example, than that is the problem.
You will then need to consider which of your devices has become infected by malware and take steps to remove it.
There is no point trying to get delisted from the Spamhaus blocklist because it is a realtime list so as soon as suspicious traffic is detected your IP address will go straight back onto the blocklist.
Post back with the results of your IP check.
In the meantime the workarounds are, either to switch to mobile data before sending emails from your apps, or to send using the VM webmail service on the VM website.
