Thunderbird is fine. K9 doesn't do OAUTH2 yet
Thunderbird on my desktop is fine.
Are there any good alternatives to K9 on Android? Hopefully it will support OAUTH2 by the time Google pulls the plug.... but contingencies and all that!
The clock is ticking for businesses using what Google defines as a "less secure app" (LSA) to access services like its G Suite mail, calendar and contacts. New accounts will be blocked from using LSAs from June 15 2020, and all access will be disabled on February 15 2021. Google's latest announcement is specific to G Suite, …
I've been using AquaMail on Android for a few years now, and have nothing but praise for it - regularly updated, and proactive on security (OAUTH2 on Google accounts was implemented agreed ago).
Handles multiple accounts, and works well with Exchange Server / Office365.
Well worth a try.
Well yes but actually hahaha NOPE. Thunderbird still doesn't support OAuth with POP3. And before you go the standard "but whyyyyyyyyy would any sane person want to use POP3 in 2020?!?" route: with all due respect, that's none of your concern.
Thunderbird is fine, but the setting authorizing LSAs gets reset about every three months. Then I have to update my parents' Google account to re-enable their Thunderbird access (at 87, they seemingly can't get used to the Web interface). I foresee the day Google decides they must see ads to access their mail.
For many years I have been using POP3 (IMAP doesn't fit my needs) to fetchmail from pop.gmail.com and, at times, SMTP to sendmail to smtp.google.com. This ancient setup has huge benefits for me. Among other things it does not tie me to a specific user-facing client or even a to specific local user on a multi-user system. On top of this the way I filter and organize my mail on the client end is completely detached from the woefully inadequate GMail facilities. And I have many, many years of mail - long predating Google - just the way I like it. The way GMail - or any other webmail - organizes mail is certainly not the way I like it. So I basically use it as a relay/SMART_HOST/whatever, for my personal accounts and a personal domain, with the ability of accessing mail on my phone in the rare cases where I need to and of switching ISPs without changing a bit in my mail setup thrown in for free. User/password has never bothered me one single bit where mail is concerned.
Now I can't figure out whether my setup will stop working in February requiring me to completely overhaul my whole system - a much more complex proposition than reconfiguring a single user-facing application - and suffer from horrible pain in various parts of anatomy. Does anyone here understand if such a setup will be affected? E.g., fetchmail does not seem to support OAuth. But then it is not a user-facing mail client. The documentation of the change does not seem to cover this case. I have not yet found all the docs or got to the right support channel - the one that will not just tell me to use a modern application.
Hell, maybe moving away from Google will become not merely a good idea, but a necessary step?
It sounds like gmail isn't really suited to your setup, despite the shoe-horning you've done.
I strongly suspect that fetchmail will stop working when they implement this change, but remember that it is only targeting g-suite users this time around.
If you're using your own domain, you'd be better off hosting it elsewhere - basically any hosting provider will facilitate what you need. If you're using a gmail.com address, this at least gives you time to start migrating to one that you can actually control.
"Probably more the former..."
Google's whole business strategy is built up from leaning on it's monopoly in other areas to force more of it's products down people's throats - these days, I can't seem to get more than a couple of videos on Youtube before an ad (uninterruptable, natch) for Stadia, or G-Suite, or some other Google offering gets foisted on me.
And then, of course, there's how Chrome became the number one browser: yes, to us in the tech/dev sphere, it was functionally "better" than the competition at the time, but I'm willing to bet that it was the great big "download our browser" button on all the search pages that did it for the masses...
... okay, so it's not as bad as the whole Windows/IE tying thing, but it's close...
That's it for KMail then as Google revoked the API key and won't give a new one...
Well, that is it for me as a customer as my current method is only via password. I might be the only person, but if google wants to ostracize its customers, then so be it. I do not have a smart phone and if I purchase one, it will never be used on google. Oh well, I guess I don't care that much about the internet. I don't need google, but they need me for my data.
One of these days they will get back to their main goal of two decades ago which was to support the customer before letting big business take advantage.
Yahoo still do POP3 access - slightly unreliably of course!
MS (outlook) also provide 'free' and POP3 access but no (obvious) means to bypass the web interface to check for spam (same issue as google)
I use A&A email service for a small fee (couple of quid per month) and they offer IMAP and POP3 and you can set up a filter in the web interface to force spam-detected stuff in back to the inbox so you always see it in your email client. https://support.aa.net.uk/Category:Email
If not UK-based you might want to look at other small-fee email providers like fastmail, etc.
This change -- designed to force legacy customers off of competition software and on to a system that ties all their activities to a single account, for advertising and identification -- only really affects downloads. Sending mail, as your printer does when it scans to email, is not affected.
