I´m tuning up a FreeBSD+postfix gateway for a sending a mailing list of
450K messages (ok, ok, there will be 2 or 3 postfix outbound gateways).

The gateway machine is FreebSD 4.3, postfix lastest snapshot, 1 GHz CPU, 1
Gbyte Ram, /var for logging, and /var2 (2nd, dedicated disk) for postfix
queue (but dammit the cowboy put the 2nd disk on the same ATA channel,
rather than on 2nd ATA channel, to be fixed).

postfix master.cf has 400 SMTP, and 200 SMTPD, and nqmgr.

I´m using the "SMTP server test" tool found here:

http://www.icewarp.com/download.html#MERAK

I´m sending from Paris to Texas, with return address in Paris. (aka "moi meme")

Using 200 x 1k msgs and 100 SMTP connectioins, there is no problem. postfix
receives 200 and sends 200 msgs.

But with 200 x 25 k msgs and 100 SMTP connections (the test pgm maxes up to
about 70 - 80 SMTP´s), I get this pflogsumm report:

   smtp
          1 Requested action aborted: local error in processing

message bounce detail (by relay): none

message reject detail: none

Warnings: none

Fatal Errors: none

So the Big Q is what happened to those 6 messages (mailq is zero)?

And

how to fix this? :

smtp 1 Requested action aborted: local error in processing

dmesg and messages, aka syslog file, show no errors.

thanks
