Re: All this talk about maximum speed
In the case of sending 250,000+ emails, this seems farely ugly in how many processes it'll be forking. I guess qmail-inject is designed to be farely small, but our current process involes writing directly to disk qf and df files in sendmail. -- Tim "Mylo" Madams -- [EMAIL PROTECTED] Sergio Strampelli wrote: Mylo wrote: Does anyone have an example Perl code that uses qmail-inject? $sendmail_command="/var/qmail/bin/qmail-inject"; open(SENDMAIL, "|$sendmail_command -f$mailfrom $rcptto"); print SENDMAIL $s; close(SENDMAIL); $s cointain the mail, with RFC headers if needed.

I thought they were the same thing. What's the difference? You probably didn't understand what I was trying to say. Inject say a thousand recipients in one qmail-queue (or inject, or sendmail, if you wish) call. Make sure you are not injecting them individually, if you can. That way, the queue system has less work managing them. The difference between sendmail-clone/qmail-inject/ qmail-queue is just the interface and the number of execs needed. qmail-queue is closest to the raw performance your IO subsystem is capable of. -- Havoc Consulting | unix, linux, perl, mail, www, internet, security consulting +358 50 5486010 | software development, unix administration, training
Re: All this talk about maximum speed
unfortunately each message is customized for each recipient with their account information, so I can't clone the same message to multiple recipients. Which, as I understand it, would require one qmail-inject (or qmail-queue) per recipient. Which is 250,000+ processes coming outta my perl script. Although this machine is dedicated to this task, that still seems like a nasty thing to do. I'm just looking if there is any smooth way of stacking messages into a single pipe of qmail-inject or anything tricky like that to save the ammount of processes. Thanks for your help :) -- Tim Tommi Virtanen wrote: On Wed, Jul 14, 1999 at 12:53:03PM -0700, Mylo wrote: In the case of sending 250,000+ emails, this seems farely ugly in how many processes it'll be forking.

Thanks for your help :) You can always open a pipe to qmail-smtpd, or qmail-qmtpd. They'll happily eat all the messages from a pipe, but you can't avoid the exec per queue injection. There just is no way. Are you sure the qmail-VERH patches won't solve your problem? They allow you to embed the recipient address in the message body without creating multiple queue messages. -- Havoc Consulting | unix, linux, perl, mail, www, internet, security consulting +358 50 5486010 | software development, unix administration, training
