It looks like the server is sending an invalid FETCH response. What server are you connecting to? Do you know what server software your email provider is using?

agalanin commented 1 year ago

@cketti, I'm connecting to imap.yandex.ru. Unfortunately I don't know what IMAP server software running on this server. Probably it's something proprietary.

cketti commented 1 year ago

Can you provide the full MIME structure of the message causing this error?

agalanin commented 1 year ago

I replaced file content with (base-64 encoded file) but preserved MIME structure

Hello Alexander,

I have been trying to reproduce the issue you described (in Samsung A6, Android10, With a Gmail account ), but I am having difficulty doing so. I was wondering if you could provide me with more information on the scenario you experienced in order to help us resolve the issue.

Specifically, could you please provide me with more details on how to reproduce the issue, as well as any other information that could be helpful in diagnosing and fixing the bug?

Your assistance in this matter would be greatly appreciated. Thank you for your time and help in resolving this issue.

Best regards, Husain

mhf1998 commented 1 year ago

could you attach a picture or video for this scenario?

agalanin commented 1 year ago

There is nothing that I can record on a video or show on an image. All messages starting from problematic one are not displayed in UI without any visible errors.

Probably the issue is related to my mail server (https://mail.yandex.ru) since it can't be reproduced with GMail. You may register an account for free.
