I forgot to say that with 0.72 the message file format passed to MAILPROC.TAB external programs is changed. Before it was the raw message file, while now it contains the spool header ( like the one passed to filters and custom domains external programs ). This will avoid XMail to create redundant copies of files and it makes my test machine ( Dual PIII 1GHz 256Mb RAM 100MHz Dual Eth ) to relay ~160000 msg/hour with static relaying. - Davide
