Hi, Guru

One of the server able to send in the reasonable timing. but another not, it delay almost one day or two days but mostly not send at all.

below is the syslog when i try to send out the mail.

GOOD Server

Hi All

I had solve the problem already..

i compare the two sendmail.cf
i found that the sendmail.cf file is same with each others
i restart both the sendmail service.
but the problem still assist.

Then i decide to manually add the relay in the DS, by default, the relay value is null.
after change it, it works in the "Problem Server"

but how come by default the server cannot recognize the correct relay?

cn you traceroute to the sending side and also provide the sendmail log ouyput?
