Hi there, i have a problem on my primary mail server. it runs debian woody and sendmail. it is forwarding mails with the mailertable feature to our customers mailservers. the customers are connected to our PoP via leased-lines.
here the error from the mail.log Apr 9 15:06:11 mx1 sm-mta[2220]: h39D1BoU002214: timeout waiting for input from [customer mailserver's ip] during client greeting after 2 to 3 retries the mails are delivered ... so the messages get deferred for 1 to 3 times and so the mail delay is 5-15 minutes, wich is not acceptable for out customer. Have played with the timeouts but this doesn't improve the mail delivery. Every time i telneted to port 25 of the customer server the greeting from the customer's server took not longer than 1 second. So it has to be a problem of the sendmail configuration. It happens not only to our customer, as i can also see this problem happening with other internet mailservers. The leased-lines are up and I run netsaint to check the customers smtp server. The banwidth usage on the leased lines is never obove 50% so smtp traffic should go through without problems. The bandwidth is between 2 and 6 Mbit/s Thanks in advance for any advice you can give me!
