CFMAIL Send Limit?

[bernarda]

CFMAIL has been sending to only a partial list of recipients. I have tried two
methods for sending mail, both using a function.

In the first I looped through the list of recipients sending each a separate
email.
In the second method I placed all recipients in BCC, placing the sender's
email in the FROM and TO field.

I am sending to several batches of recipients. I have three recipient lists
each totaling 38, 39 and 107. The under 40 lists appear to succeed just as well
as smaller lists. The 107 only sends to part of the list. There are no apparent
errors in CF admin or IIS SMTP. I have set IIS SMTP with no restrictions; it
can send an unlimited number of messages per connection and to an unlimited
number of recipients per message. All send tests with CF and other applications
work in this environment except in this case.

We staged some tests with the assistance of our network Admin using Domino's
SMTP server. When we send to the 107 batch it showed only about forty messages
arriving to the SMTP server. What happened to the rest?

Short of breaking the list apart into segments smaller than 40, is there a
setting in CF Admin or within the CFMAIL tag to overcome this restriction?

I?m working with CF MX 6.1 Enterprise, Windows 2003, IIS 6 with SMTP.

Thanks,

CF definitely doesn't have a restriction. We've used CF to send out
batches of as many as 50,000 emails and it doesn't drop any of them.

Several things you can investigate. First, check your mail logs and
your undeliverable directory and see if there are any indications
there. I haven't ever seen any emails from CF literally just
disappear, so you should find some trace of them in the logs, in the
undeliverable directory, in your CF mail queue, or possibly in your
SMTP server's queue (although its sounds like you've looked there).

Bear in mind that all CF really does is generates the mail and hands it
off to the SMTP server, so once it successfully hits the SMTP server,
as far as CF is concerned it's done its job. The task is to figure out
from following the trail of emails where things are getting blocked,
lost, or otherwise prevented from getting to the SMTP server.

We had the same problem Only a partial list was send
it was couse by two problem we found :
1: if the the to "" can not empty empty
2: the email server could not keep up with coldfusion
when i send otu small packet it would go very smooth
we upgraded to a full time stand alone email server and we can sent about
100k emails with not problems
