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.

Hi ofer I checked with sysadmin the smtp class is B only.Also I configured the SMTPCONF job to meet my installation and started the SMTP task then what else I need to do for sending mail from MVS .

Robert Sample · Posted: Tue Sep 09, 2008 8:46 pm

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

Hi Robert ,

lease do not post images,
a plain text cut and paste gives he same info with less bandwidth utilization

Robert Sample · Posted: Thu Sep 11, 2008 5:07 pm

Are you seeing any messages in the message log for the SMTP job? We see messages sometimes like

arunkumarvks · New User Joined: 16 Jun 2008 Posts: 30 Location: Chennai

"EZA5477E 09/11/08 02:01:06 Unable to Deliver Note 00000006 to <????????@********.com>"

Hi All,
Now i can able to send the mail.But the problem is i can able to send the mail to within the same MVSHOST. if i am trying to send the mail to other SMTP server like Gmail i am getting the following errors,

Subject: Undeliverable Mail

MVSHOST unable to deliver following mail to recipient(s):
<USERID@SMTP.GMAIL.COM>
MVSHOST received negative reply:

Can any one help me to resolve this problem.Thanks

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.

Yes Robert, I also tried that, but i got same error msg...

0> 552 Too many hops - threshold exceeded
1< 552 Too many hops - threshold exceeded
1> QUIT

Robert Sample · Posted: Mon Sep 15, 2008 6:37 pm

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

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.

hi Robert, any info about this....

Robert Sample · Posted: Thu Sep 18, 2008 5:29 pm

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.

Hi Robert & all, Now i can able to send the mail, Thanks a lot for your valuable support.I am always looking forward your coperation.

Robert Sample · Posted: Mon Sep 22, 2008 5:20 pm

Arun: what was the problem? Knowing the solution might prevent someone else from having a problem in the future.

arunkumarvks · New User Joined: 16 Jun 2008 Posts: 30 Location: Chennai

In my firm firewall are installed. so i cant able to sent mail into the other mail server.so that the network administrator configured my mainframe SMTP server IP address into their firewall.This is the solution for that problem.Thnaks

Good to hear it is working - thank you for posting the solution
