Hello. I have a new Samsung Galaxy Sii on the 3 network. My POP3 email is provided by Plus.net. I set up the email account details online using Samsung's "Configure phone" utility. The same settings have worked for me on various other phones including the Nokia N97. When I try to send POP3 emails via the mobile network they will stay in my outbox until the phone connects to the wireless network and then sends them. I receive POP3 emails without any problems when on both wireless or mobile network. When I check outgoing server settings I receive the message : "Checking outgoing serve settings" followed by "Setup could not finish - unable to connect to server." When I check incoming server settings I have no problem. I have no problem with internet access over the mobile network. My APN type is "internet + mms". Both 3 and Samsung recommended a hard reset but that did nothing. Does anyone have any sage advice which might help get my outgoing email working over the mobile network? Thank you!
