Problems with horde/imp

[UnKnown <rak@burst.fcien.edu.uy>]

Hi:
	Today i started to recive a strange message from the web mail, in a
sertein moment a user was reading his mail trough imp then the server drop
her out with the message " Either you have logged in incorrectly or your
login has expired. Please login again. ", all the accounts seam to be block
by the webmail. But in the other hand they are all accessible trough ssh or
console. The page is redirect to https instead of the normal http.

	If any one can give a clue I just run out of ideas.

	Thx,
		rak
