problem with sendmail

[razat gupta]

Hello Everyone,

I have a problem using sendmail. Whenever i try to send mail using mail
or mutt commands, the mail is not recieved at the destination email-id.
(not in all cases but in certain cases)
When i view the log for sendmail after using command mail or mutt, it
shows me an error message like :

"lost input channel from mail025.xyz.com [ip address] to MTA after rcpt"

can any one tell me whats the reason.

sometimes mail command functions properly with mail025.xyz.com
But sometimes it produces the error as stated above.

regards,

Razat
