Gandi.net Groups

Hi guys,

 I am not receiving any emails on one of my domains for a couple of days
now. Some contacts told me they sent me emails I never received. Btw,
they did not get any bounce.

 Checking the status of the domain on Gandi's web interface I saw in the
Gandi mail part that instead of having the space left for the 1GB, I
have "Disk space: unavailable".

 The mailbox is well defined on the faulty domain. I am always getting
my emails with Thunderbird without keeping them on the server, so space
should not be a problem here.
Gandi mail is working fine on another domain...

 Any clue about this problem before I contact the customers' support ?

 Thx in advance.
