trouble with gmail

hello,
I can receive emails OK for this hosting company address but gmail is 
not working.
I have turned on the allow insecure agents bit at gmail.
Used fetchmail in the past and it worked OK except gmail keep changing 
the fingerprint or something.
This new debian testing installation doesn't seem to have fetchmail as 
an option but I want to use getmail to see if it works nicer with ssl if 
I get around to it.

this works OK

[retriever]
type = SimpleIMAPRetriever
server = sub4.homie.mail.dreamhost.com
username = myrealusername@mydomain
password = ********

[destination]
type = MDA_external
path = /usr/lib/dovecot/deliver

[options]
delete = true

this isn't OK

[retriever]
type = SimpleIMAPRetriever
server = imap.gmail.com
port=993
username = myrealusername
password = ************
mailboxes = ALL

[destination]
type = MDA_external
path = /usr/lib/dovecot/deliver

[options]
verbose = 0
delete = false
message_log = ~/.getmail/log

I've tried various options
username with and without the @gmail.com bit
and using getmail default port.

get message
getmailrc0: operation error (IMAP error (socket error: EOF))

Is there something blindingly obvious I'm missing ?


cheers
