SASL forward problem

Hello,
I use posfix as forwarder.
The target server is connected via stunnel4. It was working, but now
I have changed ISP and the new smpt server has problem with Posfix
as client.
Here is TCP stream from Wireshark:
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
220 mailout2.t-email.cz ESMTP
EHLO 251-43-13-46.tmcz.cz
250-mailout2.t-email.cz
250-PIPELINING
250-SIZE 15360000
250-VRFY
250-ETRN
250-AUTH LOGIN PLAIN
250-ENHANCEDSTATUSCODES
250-8BITMIME
250 DSN
AUTH LOGIN
334 XXXXXXXXXX
YYYYYYY
334 XXXXXXXXX
YYYYYYY
235 2.7.0 Authentication successful
MAIL FROM:<jiri.panek@email.cz> SIZE=517 AUTH=<>
RCPT TO:<jipan@soukroma.cz> ORCPT=rfc822;jipan@soukroma.cz
DATA
250 2.1.0 Ok
555 5.5.4 Unsupported option: AUTH=<>
554 5.5.1 Error: no valid recipients
RSET
QUIT
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
If I set this server direct (in place of 127.0.0.1 == Postfix) in
Evolution with SSL and authentication, the mail is send OK!
(Such ESMTP communication I can't follow of course).
So ... there is problem in my Postfix or in ISPs SMTP server.
Can someone help me please ?
Can I configure my Postfix to be more compatible with the other
server ?
The problem is in format of FROM+TO ESMTP commands.
If I use the ISPs server in mode without SSL and SASL, then Postfix
can forward to him.
In such case the stream looks like:
yyyyyyyyyyyyyyyyyyy
...
MAIL FROM:<jiri.panek@email.cz> SIZE=517
RCPT TO:<jipan@soukroma.cz> ORCPT=rfc822;jipan@soukroma.cz
DATA
250 2.1.0 Ok
250 2.1.5 Ok
354 End data with <CR><LF>.<CR><LF>
...
yyyyyyyyyyyyyyyyyyy
You see - the difference is "AUTH=<>" in first case
Thanks
