what is the meaning of this?Running /var/spool/mqueue/n5R6dVxa009552 (sequence 2 of 2)ncsu.edu': Name server timeout<'yuan@ncsu.edu'>... Transient parse error -- message queued for future delivery

while sending mail to this client mail goes in queue.

When i resend mail through sendmail -q -v command. it gives error like /var/spool/mqueue/n5R6dVxa009552 (sequence 2 of 2)ncsu.edu': Name server timeout<'yuan@ncsu.edu'>... Transient parse error -- message queued for future delivery

please suggest me!

"Name server timeout<'yuan@ncsu.edu'>"

It's a name resolution error. Your server is having trouble resolving the MX record for nscu.edu. This could be a problem with your local server's dns resolvers (not very likely unless you get this for other domains frequently) or a problem with their nameservers or a problem with data transfer between the sites.

Do these messages eventually get delivered or do they stay queued until they get returned?

Are you getting these errors for any other domains?

No i am getting only for this domain. When i do sendmail -q -v it tries to resend mail but same error i got.

please suggest

Meanwhile as per your suggestion i have complained my ISP and they have accepted the problem from thier side and doing the needful.

Thanks for your help in this regard.

What could be the reason because user is trying to send mail to this domain since 3 days.

From other domain i am able to send mail to this particular user.

These are the related IP addresses for them, can you ping all of these?

# nameservers:
152.1.1.22
152.1.1.208
152.46.13.39

# mail servers

152.1.224.164
152.1.224.165
152.1.224.166

yes i am able to ping and nslookup too from server console.

What is in /etc/resolv.conf on your server?

nameserver 10.50.0.2
nameserver 203.196.128.4
nameserver 203.196.128.5
nameserver 4.2.2.2

this is my /etc/mail/access

Can you paste the exact log error from /var/log/maillog related to sending this email? Have you tried contacting the IT department at NCSU to find out if they are seeing anything on their end from you?

From that error it looks like you're having trouble resolving their name, but perhaps the problem is they are having trouble resolving your name and that error is generated on their end.

have you tried disabling mailscanner to see if that is getting in the way?

But it says for every mail and mail goes successfully. Should i disable this option from MailScanner?

yes i have disabled now.
