Exchange 2007 Distribution List Only Sending to 2 out 5 recipients

Hi,

I have created 5 contacts that point to SMS text e-mail addresses (ie 5556667777@txt.att.net) and placed them into a mail-enabled distribution group.  When sending an e-mail to the individual contacts, they receive the text messages.  When sending to the distribution group, only 2 of the contacts receive the text message.  Reducing the number of members in the distribution group to 2 enables both recipients to receive the text message (including members who previously did not receive the sms, while 2 others did).

Checking the SMTP send log after attempting to email the full distribution group reveals that, indeed, only 2 messages were attempted:

EHLO EXCHANGE.MYDOMAIN.COM
250-atledge02.cingularme.com
250-HELP
250-VRFY
250-XREMOTEQUEUE
250-ETRN
250-PIPELINING
250-DSN
250-8BITMIME
250 SIZE 10485760
247848 sending message
MAIL FROM:<> SIZE=6332
RCPT TO:<aaaaaaaaaa@txt.att.net> NOTIFY=NEVER
RCPT TO:<bbbbbbbbbb@txt.att.net> NOTIFY=NEVER
250 Sender <> and extensions (SIZE=6332) Ok
250 Recipient <aaaaaaaaaa@txt.att.net> and extensions (NOTIFY=NEVER) Ok
250 Recipient <bbbbbbbbbb@txt.att.net> and extensions (NOTIFY=NEVER) Ok
DATA
354 Ok Send data ending with <CRLF>.<CRLF>
451 keep
QUIT
221 atledge02.cingularme.com ESMTP server closing connection
Local

I can't find any documentation regarding limits to the number of contacts one can e-mail at once, anything related to SMS text specifically (if the smtp server could even distinguish), but it does seem to be limiting me to 2 at one time.

Thanks in advance...
