I have a question on sending out large number of emails using Imail Server. We have IMail Server Version 7.07 on win2k(1gig ram) and are sending out around 7000 emails. The code which sends out emails creates 7000 spool files on the spool directory.
Actually, that's 3,500 E-mails that are being sent out if there are 7,000 files in the spool directory (unless you are using Declude Queue, in which case it would indeed be 7,000).
We have noticed that once the files are created and IMail starts sending out the emails a process called dllhost.exe begins taking up lots of memory nearly 390MB and processor usage rises to nearly 100 percent.
That's probably not an IMail issue. I've never heard of IMail using dllhost.
Does IMail have any recommendations on the number of emails to be spooled as our
server gets very slow and the sometimes emails take more than 4 hours to
reach the recipient.
Does anyone have any suggestions to tweak, improve performance of
our IMail server.
You can go to http://www.declude.com/dq.htm for information on all this. IMail v8 does include a Queue Manager that some people have reported can also help out a lot in situations like this.
