Hello Everybody,
I´m having some problem dealing with OPEN Relay Issues,
We have a postfix server 2.5.5 and we have successfully reduced the SPAM
outgoing and incoming, we have sasaulth for smtp authentication, and
everything is ok, but when I try to check my server for open relay, I do
the telnet thing, and I get the following:
220 myserver.es ESMTP
ehlo aol.com
250-myserver.es ESMTP
250-PIPELINING
250-VRFY
250-8BITMIME
250-SIZE 20971520
250-AUTH LOGIN
250 OK
mail from:t...@aol.com
250 OK
rcpt to:t...@hotmail.com
250 OK
data.
354 Send it to me, end with <CRLF>.<CRLF>
.
554 5.7.1 <t...@hotmail.com <mailto:t...@hotmail.com>>: Relay access denied
The Relay Access Denied its working but only when I try to send the
message, and what I really want is to give me a Relay Access Denied when
I put the RCPT TO:, it should only allow a RCPT TO:us...@myserver.com,
because when I do the checkor.com or mxrecords.com on my server, it
shows that we could be an open relay, because they are able to do the
mail from and rcpt to: different hosts, and that is causing a problem on
senderbase.com reputation.
If you need the configs, I will feel free to give it to you guys.
Thanks a lot in advance everyone!!
You have some other software interfering with the SMTP
transmission. Postfix does not behave in this manner.
If you need further help, please provide full evidence,
including "postconf -n" output, master.cf contents,
non-verbose postfix logging.
