Thx for the hints.
Actually, I'm not appending, i'm simply "copying" (ie creating) the attachments to their own files on the remote system, but without creating a local copy first (inefficient).
I've tried this test prog:
$filename = "testfile.dat";
$payload = "qwertyuiop";

$args{user} = "xxx";
$args{password} = "yyy";
$host = "s.a.c.u";
$path = "/some/path/".$filename;

print "connecting\n";
$sftp = Net::SFTP->new($host, %args);
print "open\n";
$handle = $sftp->do_open($path, SSH2_FXF_WRITE | SSH2_FXF_CREAT);
print "write\n";
$sftp->do_write($handle, 0, $payload);
print "close\n";
$sftp->do_close($handle);

[download]
(where I've obscured the real values).
but it says

Permission denied at /usr/lib/perl5/site_perl/5.8.5/Net/SFTP.pm line 62

which is this line

$ssh->login($param{user}, $param{password});

I've tried replacing this with the hardcoded vals from my program and printed out the host value (looks ok), but same error.
FYI, I can successfully login manually from the cmd line using the same values(!), so I'm stuck...
Any ideas??
Cheers
Chris
