HI all Just an FYI on the below, all worked great got the user to make max recipients in a mail to 50 and I set smtp_accept_queue_per_connection to 51, the server pumped out the mails faster than before and half the time :) and did not even put the server under strain.
Was about 30000 mails in 4 hours :) and could have been more... so the trick is don't put to many recipients in a mail as takes longer to process mails :) Thanks hope this info is usefull to someone out there -----Original Message----- From: Nigel Metheringham [mailto:[EMAIL PROTECTED] Sent: 25 January 2008 15:43 To: Peter Kirk Cc: exim-users Subject: Re: [exim] exim and queue On 25 Jan 2008, at 13:17, Peter Kirk wrote: > That's why I was hoping if I can avoide using a queue for messages and > just send them out straight away, then this would send them faster as > they would not sit in a queue for an hour or so but I just wanted to > know if this would kill my machine? Ah - so my reading of this thread gives the following implications:- 1. The XP box fires a whole pile of messages, each with one recipient (assumption made on the basis that you say your queue gets to 15K plus), probably sending as many messages in an SMTP session as it can. 2. The majority of these messages end up sitting in the queue for an hour (ish) before anything happens. I would guess that your queue run is approximately hourly, or at least not very frequently. Exim always puts mail into the queue - by putting it on stable storage (ie to disk with a sync op) it can guarantee (as far as it can) that the message won't get lost due to system outage. Unless your box is suffering from severe overload (and with VMWare ESX you have some decent tools to check on the loading) I'd suggest you want to run queue runners more frequently. You could increase smtp_accept_queue_per_connection but that risks overloading the box if it receives several thousand mails at once. Running a batch more queue runners - especially around the time that the mass mailing is happening, will probably help a lot. But check the box load to ensure its not being swamped.
