RE: "No SMTP response to data-dot"-message and delivered the message like 10 times

[Michael Meier]

I don't think so. I've send a lot of e-mails just before that e-mail and 
a lot afterwards from exactly the same ip address, also using 
thunderbird...
but the problem only appeared with that single message.
And as I said, the really annoying part was, that the message got 
delivered more than 10 times (each time I deleted it, it reappeared a 
few hours later again, first I thought I'm becoming crazy ;-)))

Could this be part of the problem? It says MTA-BLOCKED because it's an
open relay? Which host is IP address 213.193.81.54?

Subject: "No SMTP response to data-dot"-message and delivered the
message like 10 times

Hi all

I've got my own server using postfix and amavis (2.10.1-2~deb8u1)
under the current debian stable (8).
Yesterday I received a big jpg-file (11MB) which I wanted to resend
using Thunderbird.
I've sent the jpg to 3 receivers, of which 2 are on my own server and
1 is on hotmail.
After a while a got a mail from my mail delivery system, saying 3
times, for every receiver:

<us...@hotmail.com>: host 127.0.0.1[127.0.0.1] said: 451 4.5.0
     id=09573-03 - Temporary MTA failure on relaying, from
     MTA(smtp:[127.0.0.1]:10025): No resp. to data-dot (in reply to end 
of DATA
     command)


But at the least the receivers of my server received the mail anyway
(i'm not sure about the hotmail account, I think there it arrived only
once). The problem is, that the server tried to resend the mail several
times. At the end I received the same email 12 times!
Each time it tried to resend it, the log files looked like that:

I guess amavis got some problem with the big attachment?
Could there be some kind of missconfiguration?
So far I never had problems with amavis. Well, it was the first time,
that I accidentally send an e-mail to myself, otherwise I wouldn't have
noticed the whole problem...

thanks in advance for any hints
Michael
