Internal Error

[inter7]

Hi,
When create user with more than 11 letters, sqwebmail enter the first time
without problems. I send to this user another mail with atchment and the
next time, sqwebmail says

Internal error (module sqconfig.c, line 63) - contact system administrator

I think maybe, is the large of the username , this not happens with user
with 8 caracters or less.

Please somebody..help me
