Minor typo:
postconf -e smtp_discard_ehlo_keywords=size
then postfix reload.

Hi,
got it. Thanks.
Btw. for some reason for Postfix: 2.6.6
[root@icinga2 icinga2]# postconf smtp_discard_ehlo_keywords=size
postconf: warning: smtp_discard_ehlo_keywords=size: unknown parameter
it doesn't seem to know the parameter. Strange but maybe you might
want to know.
Greetings

Hi,
I have a Postfix set up to relay the messages to an Exchange server.
It declines the mails with
ntern_mail.someurl.de,08D7265A6F30DBE4,12,10.32.68.13:2525,10.32.66.152:49726,*,Tarpit
for '0.00:00:05' due to '550 5.7.61 SMTP; Anonymous client does
not have
permissions to send as this sender',
There are many responses when I search the web for that.
It works manually with telnet mail.someurl.de.
From the same IP address that Postfix is using?
I suspect it is because Postfix send in the Envelope address for
some
reason the SIZE=423 with it
MAIL FROM:<tko...@someurl.de> SIZE=434,
How can I disable the sending of the SIZE parameter?
postconf smtp_discard_ehlo_keywords=size
postfix reload
But that is just to convince yourself that size does not matter.
It will also waste bandwidth when an email message is large.
