Error 535 with Gmail SMTP: Username and password not accepted
Have been a devout Opera user across many platforms for more than a decade. I particularly like the simplicity of the integrated mail client in the desktop version. However, in the last few days I have encountered a problem which may mean I have to stop using the mail client unless I can find a solution...
I buy inexpensive web hosting from an Indian company which is notorious for compromised CMS's, dodgy webmasters and lax security. It suits my needs very well, except I have found recently that mail routed through the local SMTP server seldom makes it to the recipient because my outgoing mail server is regularly blacklisted due to other sites hosted on the shared hosting package. Therefore, I have decided to (temporarily*) route outgoing mail through the Gmail SMTP server.
Enabled POP in Gmail, registered the e-mail account on my personal domain and proved ownership of it. I entered the following credentials for the outgoing mail server in Opera (12.17):
TLS enabled (no SSL option in Opera 12.17)
Authentication: Auto (Auth Login)
Although it works perfectly on my iPhone (albeit over port 993), when I try to send e-mails in Opera I receive an error message:
The server responded: 535-5.7.8 Username and Password not accepted. Learn more at
535 5.7.8 http://support.google.com/mail/bin/answer.py?answer=14257 [....] - gsmtp
Followed all the steps on this page, including the unlock captcha, choosing a secure password and enabling less secure applications, but still nothing. Found an Opera user encountering a similar (530, not 535 error) here: https://productforums.google.com/forum/#!topic/apps/o8IuVu-ta9o - the solution was to activate SSL and use port 465.
Opera 12.17 doesn't seem to have an SSL option. Is there something I'm missing?
Any suggestions appreciated. Thank you in advance!
* Ultimately I want to stop routing my outgoing mail through Google and set up an OpenSRS (or similar 3rd party hosted mail solution with a good reputation). I cannot afford to do this at the moment!
