And if you found technical solutions on TBird's site, then common courtesy would be for you to link them here.
... aaand after 20something years of being online and admin in three forums here comes Phred.
Thank you Phred for pointing common courtesy to me. Allow me to explain: Because I am a new member on this forum I am not yet allowed to post external links
Now can we be friends Phred?
I may be misunderstanding you, but why do you expect AM to fix a problem that is on Yahoo's side? If the issue also happens on Thunderbird, then it's Yahoo's problem, not AM's or TBird's.
"problem on Yahoo's side" is one way of looking at it. Admins configure servers in various ways because they want to. So in Yahoo's point maybe they are not doing something wrong.
For example I personally had problem with a server that had a problem with the following:
Content-Type: text/plain; charset="UTF-8"and yet it accepted this:
Content-Type: text/plain; charset=UTF-8What can I say. S**t happens.
I came here seeking a solution not demanding anything. And Yes TB has this option to solve this even if it's free and open-source. So maybe, and without any disrespect, a paid app like AM should make an option available to solve this OR it could write in the FAQ or in Play Store something like: "if you wanna write Greek (and other langs I guess) with Yahoo mail please know that you can't!"
Either would be acceptable, by me at least
