The message you got is for information only (you didn't specify any block size at SYSUT2).
Are there any other messages? Have you confirmed with your system programmers that your SMTP class is B?

You really need to talk to your systems programmers. They have to set up parameters in TCP/IP to permit SMTP to function, and these values differ from system to system so we cannot provide a whole lot of information about setting it up. Furthermore, look up RFC 2822 on Google to get the message format -- a period on a line by itself at the end of your email is not optional, for example. |

Once the SMTP task is started, use IEBGENER or other utility to copy your email to SYSOUT=(B,SMTP). Remember to follow the RFC 2822 requirements. SMTP will usually pick up the spooled output within a minute or two (depending on system load, priority, etc) and process it to the mail server it is sending to. At that point it'll depend on routing, email size, and so forth as to how long it takes to get there.
If your email isn't going across, look at the SMTP started task log for possible errors; you can also review the NOTE and ADDRBLOK files under the HLQ specified in your SMTP configuration. If you're really having problems, enable debugging in the SMTP configuration and review the detail results in SYSDEBUG DD name for further information. |

Hi Robert i checked with SMTP started task. its working fine only also i am getting this message in Log file "IBM MVS SMTP CS V1R7 on Wed, 10 Sep 08 20:17:31 EST".
In SYSDEBUG i got this msg,
IBM MVS SMTP CS V1R7 on Wed, 10 Sep 08 20:17:31 EST
-1< EXITPARMS VER 1 ACTN 1 USER TOKEN 0 IPADDR 0 DLEN 0 SAFTOKEN ADDR
-1> USER EXIT RETCODE 4
and how to check whether mail from mainframe is working or not.
can any one send the SMTPCONF file which is working properly or send the documentation/checklist for implementing mainframe mail concept.Thanks |

Code: |
-1< EXITPARMS VER 1 USER TOKEN 0 IPADDR 0 DLEN 0 SAFTOKEN ADDR 0
-1> USER EXIT RETCODE 4 |
shows up in our SYSDEBUG so it appears that your SMTP task is starting okay.
When you send an email, you should see messages in SYSDEBUG along the lines of
Code: |
257> 220 MAINFRAME.******** running IBM MVS SMTP CS V1R8 on Wed, 10 Sep 08 0
257< HELO MAINFRAME
257> 250 MAINFRAME.******** is my domain name. I've never heard of you!
257< MAIL FROM:<sourceaddress@********.COM>
257> 250 OK
257< RCPT TO:<somebody@********.COM>
257> 250 OK
257< DATA
257> 354 Enter mail body. End by new line with just a '.'
257> 250 Mail Delivered |
The lines with the > mark data from the mainframe, the lines with the < are email data or responses from the mail server.
So when you try to send an email what does your SYSDEBUG show? |

Are you seeing any messages in the message log for the SMTP job? We see messages sometimes like
Code: |
EZA5477E 09/11/08 02:01:06 Unable to Deliver Note 00000006 to <????????@********.com> |
Also, are the NOTE and ADDRBLOK files hanging around or going away? |

Did you try sending to <USERID@GMAIL.COM>? Most mail is sent to an actual address; the mail server handles SMTP without requiring an explicit destination of SMTP.domain.name. |

The 552 message implies there's a problem with your routing table; possibly a loop in the network? If you go to your mainframe OMVS and do a ping on a common site, what do you get back? I suspect if you get the TCP/IP definitions right, the SMTP problem may go away. |

Yes when trying to send the mail to Gmail it's goes into loop mail,
and its created the dataset called 'SMTP.CONN0.LOOPMAIL' in the system.
this dataset contains the looping message's like,
Received: from MVSHOST (xx.xxx.xx.xxx) by MVSHOST (IBM MVS SMTP CS V1R
with TCP; Tue, 16 Sep 08 14:11:58 EST
Received: from MVSHOST (xx.xxx.xx.xxx) by MVSHOST (IBM MVS SMTP CS V1R

From: USERID@MVSHOST
To: USERID@GMAIL.COM
Subject: TEST GMAIL
GMAIL TEST MSG
Also how to do a ping on a common site? Do u have any common site IP address,
when i am tried to PING on my/other system which is connected to the local network
i can get the folowing msg,
$ ping 10.108.39.212
CS V1R7: Pinging host 10.108.39.212
Ping #1 response took 0.010 seconds. |

PING doesn't require an IP address; you could ping Use [URL] BBCode for External Links for example -- which would be a good test.
If you've got a loop in your network definition, you've got to get with your network people to get it straightened out before the email will go. |
