Unable to write from imap since sunday 4 september

Hello,
This yesteday it seems that imap connexion doesn't allow write.
on my two accounts imappro.zoho.eu connection timeout when I try to save a mail in draft or sent folder.
but draft can be save from the web interface, and I see it in thunderbird (and read/unread) status from thunderbird work)
am I the only one ? I tried changing password etc .. and also different imap client. Same problem.

edit: look like that as been fixed.
