Bug#293314: exim4: Exim fails to deliver messages from users like "ISOLCELL\patrick zanon"

[Patrick Zanon - Isolcell Italia S.p.A.]

Package: exim4
Version: 4.34-10
Severity: important


Dear Bug Team,
exim fails to deliver messages from users obtained from an NT
authebntication server, like user "ISOLCELL\patrick zanon". I do not
know if the problem is due to the slash "\" or to the space into the
name.

Notice that the user home directory is
"/home/ISOLCELL/patrick zanon/"

Messages are not delivered and remain into the queue:

"
cvsserver:/home/ISOLCELL/patrick zanon# mailq
      1CwImV-0000PK-18
    *** spool format error: size=3D1016 ***

      1CwIoC-0000PS-3P
    *** spool format error: size=3D733 ***
"

Thanks for any help
Cordially=20
Patrick Zanon
