Tried with the 'gnutls-cli':

$ gnutls-cli --verbose --starttls --tofu -p 587 mail.gandi.net
Processed 161 CA certificate(s).
Resolving 'mail.gandi.net'...
Connecting to '217.70.184.11:587'...
Connecting to '2001:4b98:c:521::11:587'...
Could not connect to 2001:4b98:c:521::11:587: Connection refused

How's that possible?
