FTP problems

Hi,

We are running Squid 2.1Patch2 and we have a problem reaching some ftp
sites.
If I try to reach ftp.efi.com it fails with a (146 Connection Refused).
Most other sites
are working properly.

If I try a ftp client (e.g. the Sun Solaris one) I have a working
connection in no time.

We have no access-lists.

I am sure the firewall is working properly (since most ftp sites are
reachable). I traced (snoop) the communication and I saw a valid
connection, some retry and a close (only takes a few seconds).
Here's the trace:
