I'm trying to find an alternative to the stock email client that came with my Nexus 7 (2013) tablet running Android 4.4.2. I wanted to try Aqua Mail, but when I tried to set up an account, I was told there was an Authentication error involving the outgoing mail server (SMTP). The error was "535 5.7.0 authentication failed. Please make sure the data is correct." I've been trying other email clients as well, and the data worked fine in them. The only thing I'm not sure about is that I would normally choose SSL/TLS for security, but in Aqua Mail the SSL possibilities were SSL (strict) or SSL (accept any) or something like that. I first tried strict, then tried the other one. Neither worked. I've now uninstalled Aqua Mail. I'd like to give it another try, but there's no point if I can't get Aqua Mail to accept my data. I am sure that the username, password, and address for the smtp server were correct, as was the port number.
I read the FAQ and searched the forum's messages, and I'm sending this message in the hope that someone can help. Thanks in advance.
