[imp] An error in IMP

[Si Van Ly]

Hello.

I've downloaded, installed and configured the IMP 3.2, it works real great
using IMAP. The IMP is installed on a small network of computers, I get
incoming e-mails from outside and inside of the firewall, but when I try to
send an
e-mail, I get an error in the Mail.php file, the error is:

Fatal error: Call to a member function on a non-object in
/usr/share/pear/Mail.php on line 52

Hope that I could get any help

Thanks
