Dear all, Since I deployed my postfix server two weeks ago (after getting rid of good ol' sendmail), it has two problems that I have failed to sort out. 1. From the time it got online, my uplink usage shot straight up to 100%!! Before it used to hover between 40-70%. After monitoring it for a few days and determining that this wasn't due to increased activity from my users, I throttled it at the gateway. However, I am still interested to know why it did it that way. 2. It has refused to send mails with attachments beyond 1 MB to any destination. Machine is running SuSE Linux 9.3.
