spam with doutle at (fake@domain1@domain2)


My server is crying with a spam problem. we are receiving a lot of
fake messages with virus attached.

the messages comming from an account like
... at mydomain dot ... at spammerdomain dot com with content very simlilar
to the messages sended by our real contacts.

How can i block that? im trying with amavisd-new and postgrey but dont work.

maybe can i use some regexp?

thanks a lot

is possible modify the source address based on the subject?

Is possible rewrite the sender address on a send mail when the subject
have some special expression?

By example: if i send an email from <a href="mailto: ... at domain dot com"> ... at domain dot com</a> with the word in
the subject UPDATES, so send the email like sended FROM
<a href="mailto: ... at domain dot com"> ... at domain dot com</a> ??????

can i do that with regrex?

<a href="" title=""></a>

Really and a little bit confused with that Readme.

Thanks in advance.

Many copies of the same message in the mailbox


i some users are reporting me to they are receiving many copies of the same
message. the remitent just send 1 message and the recipient receipt 7 or
more copies of the same message.

we check the send mail folder in the remitent (outlook 2010) and just have
the message sended 1 time.

the copies received in the destination folder have aprox 4 or 6 mins
between them.

can be a client sender problem? how can i verify that?

thanks and regards.

can i save and keep a copy in the MX secundary queue?


I have a secundary MX managing the queue when the main MX is no
available. All work fine. The main MX is on line again and the
secundary MX send the messages to them. But we need an special
feature to some specifical accounts:

if the secondary MX receive a message to <a href="mailto: ... at domain dot com"> ... at domain dot com</a> and the main
MX is not available, the user crm need access to the message stored in
the secundary MX.

messages lost


This is my first post. :)

I have a mail server with a very rare issue. Many users was reported
me to some messages was not arrive to the destination. I enable a
always_bcc account to trace all the messages, and i detect, in many
cases, to some lost messages are with bad destination info or blocked
by spam filters in the destination servers. But some messages
continue without any notice.

My boss was send the last friday aprox 50 messages. He asked me about
why not all the messages was correctly received by the destination
account (both in the same domain and server).
