Hi there,

Ubuntu + Apache + Sendmail

Send mail success:

Help!
Is there any wrong config?

Thanks.

It sounds like mail.domain.com isn't accepting mail to c2@domain.com. Have you contacted the domain.com folks to ask if their mail system is working properly?

c2@domain.com can receive email from other mail.box.

Well, they are accepting mail from you at this time, and the reason is:

"451 Temporary local problem - please try later"

Whoever operates mail.domain.com will have to check their logs to see why that is. How large is the message? Maybe it is too large.
