Mr. Vasilyev,
we together with Paris Geek tested again AquaMail on azet.sk server. We sent to azet.sk account more than 50 messages and we sucessfully retrived them from server also from my Samsung Galaxy Tab 4. But the case is more complicated. We retrieved just 50 messages sinc today. But in my case were deleted 1000 emails sinc 2009 and on INBOX account remained 40 messages 2 weeks old. So the test must be repeted after 2 weeks when will be on azet.sk account 2 weeks old messages, than we can be sure that my case was occasion and not the rule. I did not did anything with setup of webmail accout on azet.sk and I worked as it is sinc 2009. I also access the azet.sk account only with another AquaMail application from my phone and did not deleted anything. According the rules of webmail server azet.sk, deleted messages have to be after deletion in trash for 30 days. But in trash I do not have any deleted message. All others folders on azet.sk account remained untouched. It does not seems be problem with azet.sk server, because on other devices with other version of Android, AquaMail work with azet.sk server correct. Also I with AquaMail on my phone and with this account I had no problems. This cause was just when I bought new Samsung tablet and setup your AquaMail on it.
My old 1000 messages will nobody return to me. That I am sure now. I discus here because it will be good that you correct your AquaMail that it will no happend to anyone like me. I am sure that it was not my mistake or that I did bad setup. It happens evrything stright simply only with simple install a and setup of account.
Thanks.
