>- see footer for list info -< If you go into the SMTP service properties, click on the "messages" tab, here you will find a number of settings that will cause you such problems. You will probably need to increase all of them.
Although if you are going to doing bulk mailings, I would not rely on the SMTP server that comes with IIS. You should have a dedicated SMTP server, or at the very least install something that gives you more control and better logging. There are a number of decent mail server products that come with free versions. E.G. SmarterMail hMailServer MailEnable You should also stagger your mail-out and not do so many in a single query/request. -- Russ Michaels Certified ColdFusion Professional My Blog: www.russ.michaels.me.uk Tel: 0845 8620034 Fax: 07092 300330 Skype: russmichaels Commerical ColdFusion & BlueDragon Hosting: www.cfmxhosting.co.uk FREE CFML Developer hosting : www.cfdeveloper.co.uk -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Gary Sent: 26 October 2008 20:09 To: Coldfusion Development Subject: [CF-Dev] cfmail capacity limit, CF8 with Win2003 SMTP >- see footer for list info -< Hi CF'ers. :-) Has anyone encounted a limit sending emails from CF8 via a Windows 2003 SMTP server? Using <cfmail query="myMailingList"> with at least 4,000 email addresses in the query, about 50 to 300 emails aren't sent and end up in the undeliverable directory. CF logs this error: "552 4.3.1 Session size exceeds fixed maximum session size" Adobe advised me to increase the SMTP session size limit above the default 2Mb recommended by Microsoft. Okay, I increased it to 5Mb but if I try to send over 10,000 emails I run into the same problem. Increasing the session limit is *not* the correct solution. I feel this is a bug in CF that prevents it from understanding what to do if SMTP closes the session. CF should simply open up a new session and carry on making sure to resend the last emails that weren't accepted by the SMTP server. Anyone willing to share their experience or insight will be appreciated. Thanks, Gary. _______________________________________________ For details on ALL mailing lists and for joining or leaving lists, go to http://list.cfdeveloper.co.uk/mailman/listinfo -- CFDeveloper Sponsors:- >- cfdeveloper Hosting provided by www.cfmxhosting.co.uk -< >- Lists hosted by www.Gradwell.com -< >- CFdeveloper is run by Russ Michaels, feel free to volunteer your help -< _______________________________________________ For details on ALL mailing lists and for joining or leaving lists, go to http://list.cfdeveloper.co.uk/mailman/listinfo -- CFDeveloper Sponsors:- >- cfdeveloper Hosting provided by www.cfmxhosting.co.uk -< >- Lists hosted by www.Gradwell.com -< >- CFdeveloper is run by Russ Michaels, feel free to volunteer your help -<
