Hi,
I've setup Gmail in the webbrowser using an external SMTP server. With the gmail app this works fine. In Thunderbird I had to set the SMTP server again (it would not pickup the SMTP settings from the Gmail itself.)
With Aqua mail I noticed i had to do the same, using 'internetmail' and that worked. However, Aqua mails warns that it is safer to use OAuth. If I just us the Google account of my phone, choosing Gmail, I can set the SMTP server manually, I'm not able however to set the password, so I can't connect?
If I just choose the gmail account automatically it will use the gmail smtp server.
