Can't send email on 4G, but it does send on Wifi

[#1]

Until recently my wife could send and receive emails successfully on her iPhone on both Wifi and 3G/4G, but for the past few days she has found that emails sent on 3G/4G have just stayed in her outbox. Emails sent by Wifi still work OK. I use an identical iPhone and I have no problems with my connection. Any suggestions would be gratefully received!

Hi Chaswick,

Sounds like a problem with your Wife's settings, is it a Plusnet email? DM me your username and I'll talk you through set up

Thanks

Hi @chaswick,

To be honest, I'm not sure we'd need you username, but it's worth making sure that the username for the outgoing server is set as the correct username for the mailbox (username+mailboxname) and the password is correct, the server should also be set as relay.plus.net.

If these are all correct and your wife continues to experience problems, please let us know and we'll look in to this further.

Thanks for your reply. As I have already said, my wife has no problems with outgoing mail when using WifI. The problem only occurs with 4G. 

I've just done a test with her phone on 4G and got the message that her sender address was rejected by the outgoing server. Now I am wondering whether we have a problem as we are using my domain name for emails, rather than a Plusnet address. Incoming mail works fine when set up with my Plusnet user name + her name, but how can I set up her Plusnet name as a sender address? And why does it all work ok on Wifi and not 4G?

Hi there,

This will work over wifi as we allow anyone connected through our network to use our outbound mail server, however doing this wider across the whole internet would open them up to spam and abuse.

Therefore to allow your wife to send when connected on 4G but using the Plusnet outbound email server you'll need to ensure that the outbound server is set to 'require authentication'. The username and password you'll need to enter will either be your account username or username+mailboxname along with the relevant password for each.

Hooray! I've changed the settings on my wife's phone as per your instructions and it now sends emails on 4G. I now have a happy wife! Many thanks Chris.
