There were always problems with the mail-relay.3ireland.ie process on Three. Mail was ofter refused by other carriers worldwide. But to just up and remove outgong mail from customers is scandolous at best. And then to be told that all you have to do is just alter their smtp setting.
Here is the iinformation provided by Eircom to do with outgoing mail ....
Issues sending emails
Are you accessing your emails through an email client (e.g. Outlook/Mac Mail)?
When sending an email via an email client e.g. Outlook, Apple Mail, Phone etc. you are dependent on the broadband provider that you are using at that time. Therefore the email client should be configured to the broadband connection that is being used. If it's not set up correctly, emails will not send.
So much for using Thunderbird to handle my tem Eircom email accounts.
@claggan Got an email to let me know about this. I use gmail and updated it without problems but looking at the FAQs it looks like they are shutting it down and put in place a more secure system so if it gives more security then that's not a bad thing. Weird that Eircom can only 100% guarantee emails will work if using their products. I'd be fairly annoyed but maybe they like it that way ha
Hi @claggan, @Chilli-Pepper is correct, we made a decision to close the Three.ie relay system in favour of a more secure route and contacted our customers to give notice of this before it’s removed on the 31st of May. Have you tried to use the following outgoing server address: mail1.eircom.net If so, did that work for you? The webmail version should work without needing to input anything. If the outgoing server isn’t working you’ll need to contact Eircom for further help with this. Thanks
