gnutls-cli does not show response to EHLO, telnet does

[Andreas Metzler]

Hello,

it seems to be impossible to connect to smtp.jaist.ac.jp 587 with
gnutls-cli:

-------------------
ametzler at argenau:~$ gnutls-cli -s --priority=NORMAL:%COMPAT:-VERS-TLS1.1:-VERS-TLS1.2 smtp.jaist.ac.jp -p 587
Processed 152 CA certificate(s).
Resolving 'smtp.jaist.ac.jp'...
Connecting to '150.65.19.12:587'...

- Simple Client Mode:

220 jaist.ac.jp ESMTP mail service ready
EHLO openssl.client.net
[nothing happens]
-------------------

telnet succeeds. Any idea why?

thanks, cu andreas
