I have just cancelled my contract with vodafone and have taken out a sim only deal with three. The problem is I am unable to send emails using the email client (it worked fine with vodafone) I am still able to receive them though.
Just wondering if there are any other n900 users on the 3 network who could offer some advice
Google IMAP works fine for me over 3 using Secure Authentication (SSL) on port 465 (Incomming is also SSL on port 993).
From 3 website:
"To protect you and our network, we restrict access to port 25 on our network.
If you use your phone's email software and your email provider uses Port 25 for outgoing mail, you will need to change outgoing email port from 25 to 587. It is possible that your email provider does not support port 587 - in which case you should try port 465 as an alternative. With some email providers you may also have to send email using a secure SSL connection."
