This is a bug in mail.ru's IMAP implementation that is decimal numbers with exponents instead of integer values for body part sizes

Despite this, Thunderbird and Outlook as well as Mail and Calendar work correctly🤔

Is there anything possible to interfere with this behavior in Mailkit?

[chenseanxy]

Doesn't seem so, and probably there won't be a fix from MailKit's side

This feels like a recent issue, maybe ask mail.ru's customer support? Very clearly a regression from their part

Edit: Did not realize the Mailkit guy was here lmao

I would prefer to see mail.ru fix the issue, but I would consider a workaround if not.

And yes, I'm here. Randomly saw this project was using MailKit and am pretty excited that someone is using it to create an email client 😁

Very cool.

Super exited that Wino got your attention! All synchronizers leverage MimeKit and specially ImapSynchronizer uses MailKit extensively. I'm pretty sure the current implementation of Wino's imap synchronizer is not the best, and probably I did some parts very weird. If you have suggestions or tips/tricks to make the imap synchronization better you can always reach out to me. I will gladly make the required changes in the code along with your expertise.

Mailkit synchronization call for imap happens here:

Wino-Mail/Wino.Core/Synchronizers/Mail/ImapSynchronizer.cs

Line 766 in 8367efa

private async Task<IEnumerable<string>> SynchronizeFolderInternalAsync(MailItemFolder folder, CancellationToken cancellationToken = default)

Forgot to comment that I added a work-around for this: jstedfast/MailKit#1838

Will be in the v4.9.0 release when I push it out. Currently blocking on some new S/MIME functionality in MimeKit that needs confirmation that it works before I can merge & make a release.

Will update you when I push it.

[jstedfast]

Looks like I forgot to notify you guys that 4.9.0 was released.

Looks like I forgot to notify you guys that 4.9.0 was released.

Thanks! I have already upgraded the package, new release is pending in Store until I finalize couple more important fixes.
