The MTA sends no reply to the [CR][LF].[CR][LF].
If you set ConnectionLog to verbose or diagnostic you should see the
following lines in the maillog.txt
......Info: received all data - all data moved to send queue
.....Info: all DATA written to server - sent [CR][LF].[CR][LF]
If both lines are written - assp and the sender are waiting for a reply
from the MTA.
As long as I remember, the problem was related to the spam detection in
postfix (amavis). If SSL/TLS was used on localhost and a spam is detected
by amavis, the reply was missing, which causes the connection to timeout.
If amavis is used, assp connects to the amavis listener, amavis itself
connects to the postfix smtpd internaly.
the postfix debug log level 4 shows something like
Dec 19 14:05:17 web postfix/amavisd/smtpd[20135]: initializing the
server-side TLS engine
....
Dec 19 14:05:17 web postfix/smtpd[20135]: NOQUEUE: filter: RCPT from
assp.....[10.10.10.10]: <..............>: Sender address triggers FILTER
smtp-amavis:[127.0.0.1]:10026; from=<....................>
to=<.........................> proto=SMTP helo=<..................>
.....
Dec 19 14:08:18 web postfix/smtpd[20135]: lost connection after DATA
(24571 bytes) from ..........[10.10.10.10]
Dec 19 14:08:18 web postfix/smtpd[20135]: disconnect from
assp.drdos.info[10.10.10.10]
I've no clue what I can do in assp to get rid of this problem. This is the
second time the problems occurs - and only with postfix. If SSL/TLS was
disabled for the localhost connection, the problem was gone last time.

Betreff: Re: [Assp-user] Trouble with postfix
Hello
You are right, i check the mta end it was forcing the tls.
I had corrected and add in assp 127.0.0.1 in noTLSIP and now it's working
as expected.
About my first problem , do you have any ideas (about timeout)?
I saw one discussion of a similar issue has been worn in the past, but
without a solution:
"[Assp-test] Timeout issues
From: Colin<colin.waring@gm...> - 2014-07-08 14:50:27"
The only different thing is that in my case the connection between sender
and assp is closed ,
but not between assp and my mta.
Right now , after setting notls ,iwill wait until tomorrow to see if the
problem reoccurs...
