Weird ... iPhone 6 suddenly can't send email over 4G/3G

[Anonymous]

Hi

Until today I had no problems at all with 4G/3G.

All of a sudden today, I can't send emails on either of my 2 virginmedia accounts.

I can still receive emails no problem.

I can still send texts, make calls, browse the net ... no issues whatsoever

I just can't send emails!

It seems that it can't authenticate the SMTP server.

However, when I got home, switched wireless on and connected to my home network ...  no problems whatsoever.

Turn off wireless and I I can't send again.

O2 stated initiallly that since it worked on my wifi it clearly showed the network was ok.

Huh? Utter rubbish since we are talking two different networks ... it actually suggests the Virgin one is fine and the O2 network is not fine.

They suggested deleting my email accounts and re-enterring them.

Huh again?  clearly they are ok since they still work on wifi.

Just to please them so they could put a tick on their piece of A4 paper, I did it to one account anyhow and sure enough it didn't do anything.

(basically the equivalent of your ISP who suggests that switching everything off and on again will cure all known faults :smileytongue:)

Then of course I get the "Well it's email and we don't support email problems" and I should get in touch with my ISP.

Thanks O2, I'll remember that when renewal time comes round.

Naturally my ISP, though much more helpful than O2, could only suggest it was a problem with the O2 network.

O2 are adamant that it isn't.

Anybody else experienced anything similar or know if there's a fix please?

Cheers

Mark

Try resetting your network settings mate.

You need to check that you are using virginmedia's smtp server.
If you were previously using O2's it may not be working anymore.

smtp.virginmedia.com
ssl on
authenticate user (sign in)
Port 465

Sounds like an email provider fault. Have you entered the details correctly in the mail settings?

Well, to summarise :-

1) The email account settings haven't changed since 3 iphones ago.

2) I can still receive but just not send on 3G/4G

3) I deleted an account to keep O2 happy and re-entered ... no change (also double checked them with virgin tech guy and compared against my PC and laptop).

4) The same account settings still work fine on wifi so clearly all email account/server/port settings are correct.

It's not settings.

May be an issue with the smtp server rather than the phone.

What settings have you got for outgoing mail?

[Anonymous]

Yes it's not the phone at all which eliminates O2 partly

If that Apple troubleshooting link I provided hasn't helped, try a restore via iTunes

My settings are

smtp.blueyonder.co.uk

ssl off

authentication password (though virgin tells me this is not required)

port 25.

All as per recommended by their tech guy and as used for many years
