Hi all,

just subscribed to the list, due to a phenomenon I can't solve.

I dist-upgraded the system from Debian Woody to Sarge yesterday. Since
then postfix sends MAIL FROM, RCPT TO and DATA commands in *one* tcp
package. I sniffed the connection and these commands are definitely sent
in one package. The other server answers to DATA first and postfix
resets the connection.

Searching the archives and googleing gave nothing relevant to me. So,
has anyone out there seen this before ? What might it be and how to fix it ?

Below you find the output of postfinger and an Ethereal trace of a
connection. Tell me if you need more information.

Thanks in advance and have a nice time,

Joerg
