Is this a postfix problem? Receiving mail from cellphone

This is a RHEL server running postfix.

Sending email to the server from my cell phone is giving an error and I 
don't understand why. I'm hoping that someone here can shed light on it 
for me.

Here's the mail log entries that show the problem:

Dec  1 01:55:27 ec2-75-101-156-55 postfix/smtpd[31695]: connect from 
150.sub-69-78-129.myvzw.com[69.78.129.150]
Dec  1 01:55:27 ec2-75-101-156-55 postfix/smtpd[31695]: NOQUEUE: reject: 
RCPT from 150.sub-69-78-129.myvzw.com[69.78.129.150]: 450 4.7.1

helo=<njbrspamp5.vtext.com>
Dec  1 01:55:32 ec2-75-101-156-55 postfix/smtpd[31695]: disconnect from 
150.sub-69-78-129.myvzw.com[69.78.129.150]

Thanks for any help or pointers to resolving this.

You phone (IP 69.78.129.150) is using a smtp client (or smtp relay)
that is identifying itself in the HELO SMTP message as
njbrspamp5.vtext.com which doesn't resolve using DNS.

njbrspamp5.vtext.com is likely a smtp relay which simply
doesn't have a public dns entry.

You can (carefully) loosen the HELO restrictions on your mail server

It appears that njbrspamp5.vtext.com doesn't exist according to:

jbd <at> bruce:~$ host njbrspamp5.vtext.com
Host njbrspamp5.vtext.com not found: 3(NXDOMAIN)
jbd <at> bruce:~$ host vtext.com
vtext.com has address 69.78.67.39
vtext.com has address 69.78.128.199
vtext.com mail is handled by 50 smtp-bb.vtext.com.
vtext.com mail is handled by 50 smtp-sl.vtext.com.

Re: CentraLUG, TONIGHT! December 1st, NHTI Library Room 146

Added to the topic list:

- a tale of two upgrades: F9 to F10 inplace for the win! and fixing a
buggy CentOS 4.7 with a CentOS 5.2 upgrade

- overvoltage shutting down UPSes: a shocking tale!

- we'll have a copy of Fedora 10 installed with all the latest shiny
bits, and two liveCDs (GNOME/KDE) and a DVD to give away.

- a book raffle if we get at least five attendees

The Central New Hampshire Linux User Group will hold its monthly meeting
On Monday, December 1st, starting at 7 PM at the New Hampshire
Technical Institute Library, Room 146. Look for the penguin signs.

We've have a laptop, projector, network connections and hold an informal
Q & A and chat session. Possible topics might include:

- the release of Fedora 10 last Wednesday (we'll have a disk or two to
share; email me if you'd like one)
- the recent Professional Ruby Conference held in Boston (nearly
everyone at the conference deploys their apps on Linux!)
- upcoming CentraLUG topics
- recent GNHLUG meetings
- your questions

Hope to see you there!

[GNHLUG] Silly C/C++ question...

I am sure I will kick myself when I find out the answer, but...

I have a text file that for now consists of 3 lines, later it will have
  data.
  line 1: integer representing the array size
  line 2: four doubles separated by commas
  line 3: \n

Here is the code fragment that I have been trying to get to work.  I have
no idea why I am getting the output I am.

double fstart1, fend1, , M1, dt1 ;  int N;
FILE *fp;
fp = fopen("/home/workspace/input3.txt", "r"); // open input3 file for
reading
printf("input3.txt opened for reading.\n ");

fscanf(fp, "%i", &N);                                    // Find file
length ==> read first line
printf("file length is %i\n", N);                        // all is good

fscanf(fp, "%d%d%d%d", &fstart1, &fend1, &M1, &dt1);     // get fstart,
fend, number of doppler slices & dt
printf(" fstart = %d  fend = %d number of doppler slices = %d dt = %d \n",
fstart1, fend1, M1, dt1);

fclose(fp);

The output of the file is:
input3.txt opened for reading.

  Sending email from your phone, or sending SMS messages to an email address?

  Where's the commas getting cleared?

a call for collos

I'm in desperate need of a collocation facility.  The one I am in now is closing their doors just 3 weeks after I moved in!  Anyway, cheap and available are my primary concerns.  The closer to the Upper Valley (Lebanon, Hanover, White River Junction, VT, etc.),  the better but I am expecting to have to go as far as Manchester or Montpelier.  I'd even go to Nashua if I have to, but I'd like to stay closer than that to minimize down time during the move.

If you are a collo provider yourself, or work for one, please feel free to contact me directly off list or by phone if you are not comfortable posting "salesy" things to this list.

Thanks!

It would appear that is the problem, hmm, I left my K&R at home.  Do you
have a link to a K&R clone or a reference to the string command that would
be useful?  It looks like strtok would work, if I can figure it out...

Jeesh, I'm liking python more and more...
