In 2015, Outllok/Thunderbird could so it as well.
Good, then the
technical part of your previous posting was correct.
If my reply was rude, that wasn't my intention. What I did find rude was that there are posts here saying it can't be done when it can.
Email and forum communication is missing many important channels and the intentions (and the tone), which you might infer in a personal conversation from the tone or facial expressions, are easy to misinterpret.
And in your case, the words are strong and contain an unambiguous accusation:
False and honestly kind of insulting that you lie and treat users as dumb...
As Mikeone and I have already written, Kostya's statement was clearly not 100% definitive (he expressed that tentativeness), and it was
not the main focus of his posting. As a human, he made a mistake. That is not the reason to accuse him of
lying and the rest.
That's about rudeness.
Now, to share my personal view, -- from my observation of Kostya on this forum for over 3 years now, I have never seen him intentionally misleading people or treating them as dumb. Period.
As any of us, he's made occasional mistakes, which he's admitted (unlike some politicians) and apologized for.
He provides the most dedicated software support that I've seen, patiently helping and educating users about Aquamail and other issues. (And he does that for free and paid users equally!) {*}
Yes, he has his own opinion and vision. He listens to users but makes his own decisions. (Well, at least that was the case until the recent acquisition by MobiSystems.) And it is his vision that yielded this great and successful app enjoyed by hundreds of thousands (possibly millions) of users.
But as the old proverb says, he "is not a shiny gold coin that everyone is going to like". Obviously, he cannot satisfy everyone's requests (some of those are due to the time constraints, others - due to the contradiction to his vision, and in some cases there is a contradiction between requests from different users). And I personally have several things that he disagrees with, but such is life. That doesn't affect my respect toward him.
But I've seen some users who feel a strong entitlement and who through a tantrum like a 4-year-old who didn't get his candy, if Kostya doesn't fulfill their request. (Even $5 paid for this app do not give people the right to be
rude with the developer.) On a (very) few occasions, I've seen Kostya loosing his patience while responding to some
trolls rude people a bit stronger (which I, as a human, also understand), but still in a very civil manner.
--------------
{*} Compare Kostya's level of support to, say, Adobe or Microsoft: users pay high $$$-$$$$s for those products, frequently with many bugs and problems that the company refuses to fix. Their support is awful.
I hope this "larger-scale" picture shows why your accusations of
lying and lack of respect in your very first posting in this forum sound rather rude.
