hi, All

If to send emails via GMAIL SMTP server in the app - most try from various app users are OK, email is sent.
GMAIL account has the setting allowing using account by "3rd party applications".

But some end-users still get error during sending attempt: https://www.b4x.com/android/forum/threads/smtp-auth-trouble-503-or-530-error-auth.87079/#content

I found that there is some auth option at Email-clients like "POP before SMTP". Seems, it means that the email reading must be done first, before SMTP usage try.

Anyone tested this ?
It means that POP3 should be used firstly...
POP3 is also event driven, cannot be used together with SMTP in a code module...
