Re: help pls : how to optimise mail server response Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Sender: owner-isp@FreeBSD.ORG X-Loop: FreeBSD.org Precedence: bulk First and foremost, thank you very much to everyone for the fantastic response. Sorry for the late reply follow up but I wanted to try as much as possible before disturbing you all. I went to the customer's offices today and tested over a dialup to the ISP (jaring.my) - Eudora downloaded all of the mail with no problem whatsoever. However, when I returned to the office, there were a load of error messages on the console as follows : NAA00753: SYSERR(root): collect: I/O error on connection from btr-21-101.tm.net.my, from=On Thu, 5 Jun 1997 sweeting@neuronet.com.my wrote: >> The problem is that they are having a lot of difficulty >> collecting mail from the mailhub I set up for them >> on a P166 FreeBSD box with 64 MB RAM. >> We are a webcompany with 2 MB line to the same >> ISP that our customer is dialling into.

On the LAN, i only get one type of problem : the initial ping request times out. I can download mail no problem at all from any of the virtual domains on the mailhub over the LAN. It is only when dialling up to the ISP that the main problem occurs (of the mail client not being able to download the mail). >>4) I configured it inefficiently (config files below) > >We'd need to see /etc/hosts.conf and /etc/resolv.conf on the FBSD host for >clues about whether the DNS is to blame. i am not running dns on the mailhub yet but feel the console error message above may reveal the real problem. thank you once again to one and all for all of the help !!! chas surreal thought .. couldn't be the mail clients, could it ? (they are using Eudora 3.0 and netscape 3 )
