Sendmail: "451 Temporary local problem

figaro666 · 07-30-2008, 05:31 PM

Hi there,

I have 2 Fedora 8 servers that have BIND installed on them and they are used as NS servers.

I installed and configured sendmail to achieve the forwarding functionality: to send reports from some network devices to a specific email address on corporate email service. Email service is being provided by 3rd party (for a simplicity I'll call it ISP).

I configured relay from a certain subnet and smart host as ISP mail server.

I'm able to send email from the server over to any public mail services (gmail, yahoo and etc.), able to send email locally. However, when I'm trying to use a major functionality (forward of email from device) or send email from the server to corporate domain I'm receiving 451 error.

I collected a log file, which is listed below. This log file represents an attempt to send email from the server to a corp email.

Any help will be appreciated.

Thank you in advance.

451's are temporary failures. Your mail server is expected to retry again, and sendmail will. The server 209.200.229.55 claims they are having local issues. The admin at the remote server must explain why you are getting the failures.
