I have a problem sending mails from some servers to my mail server.
The mail server is installed with the help of bills toaster. The two servers I try to send from both have fqdn and the same installation (RedHat 9) out of the box with no mail modifications.
The strange thing is, that only one of the two servers can send mails to the mail server.
Look at this: [EMAIL PROTECTED] root]# sendmail -Am -vt To: [EMAIL PROTECTED] From:[EMAIL PROTECTED] Subject: test test dsfklsdfk [EMAIL PROTECTED] Connecting to mail.ruazgo.com. via esmtp... 220 mail.ruazgo.com ESMTP >>> EHLO dev.ruazgo.net 250-mail.ruazgo.com 250-AUTH LOGIN CRAM-MD5 PLAIN 250-AUTH=LOGIN CRAM-MD5 PLAIN 250-STARTTLS 250-PIPELINING 250 8BITMIME >>> STARTTLS 220 ready for tls >>> EHLO dev.ruazgo.net 250-mail.ruazgo.com 250-AUTH LOGIN CRAM-MD5 PLAIN 250-AUTH=LOGIN CRAM-MD5 PLAIN 250-PIPELINING 250 8BITMIME >>> MAIL From:<[EMAIL PROTECTED]> 250 ok >>> RCPT To:<[EMAIL PROTECTED]> >>> DATA 250 ok 354 go ahead >>> . 250 ok 1081162708 qp 8793 [EMAIL PROTECTED] Sent (ok 1081162708 qp 8793) Closing connection to mail.ruazgo.com. >>> QUIT 221 mail.ruazgo.com [EMAIL PROTECTED] root]#
Sending from this server works fine. ************* When trying the same from the other server:
[EMAIL PROTECTED] root]# sendmail -Am -vt To: [EMAIL PROTECTED] From: [EMAIL PROTECTED] Subject: test test jfkdjfkkslfjs sgkjslafgdlkfj [EMAIL PROTECTED] Connecting to mail.ruazgo.com. via esmtp... 220 mail.ruazgo.com ESMTP >>> EHLO test2.ruazgo.net 250-mail.ruazgo.com 250-AUTH LOGIN CRAM-MD5 PLAIN 250-AUTH=LOGIN CRAM-MD5 PLAIN 250-STARTTLS 250-PIPELINING 250 8BITMIME >>> STARTTLS 220 ready for tls >>> EHLO test2.ruazgo.net 250-mail.ruazgo.com 250-AUTH LOGIN CRAM-MD5 PLAIN 250-AUTH=LOGIN CRAM-MD5 PLAIN 250-PIPELINING 250 8BITMIME >>> MAIL From:<[EMAIL PROTECTED]> 553 sorry, your envelope sender domain must exist (#5.7.1) /root/dead.letter... Saved message in /root/dead.letter Closing connection to mail.ruazgo.com. >>> QUIT 221 mail.ruazgo.com [EMAIL PROTECTED] root]#
It says 553 sorry, your envelope sender domain must exist (#5.7.1). There are a ton of threads on google, but I still don't know what to do about it.
I don't really understand, that dev.ruazgo.net is allowed to send while test2.ruazgo.net is not. As I said they both have a fqdn and their setup is also the same.
I am not even sure if this is a mail server problem or if it is a problem with test2.ruazgo.net.
How can I find out what to do? I am getting pretty frustrated because I can't see the any logic why one server is allowed (can) and another isn't (can't). Please any suggestions would be really appriciated.
I searched the mail archives but no result turns up when searching for "553 sorry, your envelope sender domain must exist (#5.7.1)".
