Hi everybody,
First of all, sorry for my bad english.
Since yesterday, I have an issue with my dedicated server provider.
They consider my bounce emails as spam.
They said that my bounces have an empty "from" so they are considered as
spam by their "anti-spam" system.
They ask me to define a "from" like postmas...@mydomain.com.
I tried to define a bounce template like :
#
# The failure template is used when mail is returned to the sender;
# either the destination rejected the message, or the destination
# could not be reached before the message expired in the queue.
#
failure_template = <<EOF
Charset: us-ascii
From: postmas...@mydomain.com
Subject: Undelivered Mail Returned to Sender
Postmaster-Subject: Postmaster Copy: Undelivered Mail
This is the mail system at host $myhostname.
I'm sorry to have to inform you that your message could not
be delivered to one or more recipients. It's attached below.
For further assistance, please send mail to <postmaster>
If you do so, please include this problem report. You can
delete your own text from the attached returned message.
The mail system
EOF
#
# The delay template is used when mail is delayed. Note a neat trick:
# the default template displays the delay_warning_time value as hours
# by appending the _hours suffix to the parameter name; it displays
# the maximal_queue_lifetime value as days by appending the _days
# suffix.
#
# Other suffixes are: _seconds, _minutes, _weeks. There are no other
# main.cf parameters that have this special behavior.
#
# You need to adjust these suffixes (and the surrounding text) if
# you have very different settings for these time parameters.

by adding entry bounce_template_file = /etc/postfix/bounce.cf in
/etc/postfix/main.cf.
Then I restart the postfix service.
But I can still see bounce emails with empty "from".
Can someone help me on this ?
Thanks in advance.
Best regards,
Baptiste Lhoste
