Firstly I have my email set up with these settings:
Incoming mail server: webmail.eircom.net
Outgoing mail server: smtp.o2.ie
I have tried with my eircom wi-fi(Broadband) and using 3 data with wi-fi turned off. I get the message "The connection to the outgoing server "smtp.o2.ie" failed. Additional outgoing mail servers can be configured in settings > mail > contacts, calendars". I realise my wi-fi has nothing got to do with 3 but the outgoing server does not work with 3's server.
If I turn off 3 data and use eircom wi-fi I get "A copy has been placed in your outbox. The recipient *******@whatever.ie was rejected by the server because it does not support relaying.
What is annoying is using Eircoms standard mail settings, webmail.eircom.net and smtp.eircom.net I had no issues when I was using a Vodafone sim so obviously 3 handles these outgoing emails in a different manner. What can I do to resolve this please, as even using 3's own outgoing mail server smtp.o2.ie is not working with only 3 data turned on and wi-fi off. Has this server changed. At the moment the only way I can use my email is to turn 3 data off, turn my wi-fi on and change the outgoing server to smtp.eircom.net, hardly ideal.
