Unable to send emails from wifi at another household
I'm looking to see if anyone can give me any help or advice regarding an issue which is affecting my parents emails. At present they are unable to send any emails via wifi whether it's on the phone/desktop however they can via webmail.
I've got a virginmedia email account so I tried to send an email from it and it came up with the following error message on my phone - Failed to send email - Connection problem (522.214.171.124 Authentication Denied (VM305))
Before creating this post, I asked my parents to check for spam and it's come back all clear.
Once I've got home - the email that was sitting in my outbox sent on my VM network.
