Simple SMTP question: multiple e.mail addresses

[KU5D]

Greetings all,

I've just got a webserver up and running on the CCS 3.3v Ethernet Development board and have added e.mail (send only) functionality to it based on the SMTP examples included with the CCS stack (ex16.c). Sorting out the SMTP server address was a bit fun, but at least it's working. Now, I'd like to send alerts to multiple e.mail addresses and have tried the standard semicolon delimiter between them (have tried commas too) to no avail. Is there something simple I'm overlooking? All the target addresses are members of the same domain.

my stuff:

new CCS 3.3v Development Kit
compiler version 4.101 (with the CCS TCP/IP stack)

regards...

Where did you read to use the ; ??

I thought the convention was to use a comma.

<bkamen@benjammin.net>,<ben@benjammin.net>

(and that's how it should be on the RCPT TO: line to the forwarding mail server.)

Have you tried that?

Maybe I'll go look at the RFC again. :P

I am not familiar with the code/project you refer to, but I have written many server services regarding mail...

for mail to more than one recipeint, you need to specify a
RCPT TO: <email@domain.tld>
for each email address, as a seperate line.

Example conversation:

Connected to 127.0.0.1.
Escape character is '^]'.
220 vhost.ontura.com ESMTP Sendmail 8.14.1/8.14.1; Thu, 10 Dec 2009 21:36:50 -0800

Yep - he's right.

I remember now, I was creating mail files on the fly and if you format in the file the TO: line with multiple recipients, Sendmail takes care of the rest.

If you are talking directly to a mail server, you need to do a RCPT TO: for each destination.

See: http://www.ietf.org/rfc/rfc2821.txt

Excellent. The quick (and correct) answer is much appreciated.
