[sylpheed:36085] I received about 5000 e-mails today on Sylpheed

[YuGiOhJCJ Mailing-List]

Hello,

I received about 5000 e-mails today on Sylpheed 3.2.0.
In fact, I received all the e-mails of my mailbox a second time.
So, I think all my already received e-mails was considered as not received

That's the first time I get this issue.
On the webmail of my mailbox provider, my e-mails are stored only one time.
So, maybe the problem is because of my Sylpheed 3.2.0 mail client.

Can you explain this strange behaviour I got today?

Thank you.
Best regards.
