How To Customize The FROM E-Mail Address When Sending E-Mail From Your IBM i Server

1) Ensure PTF 5770TC1-SI57660 is applied if you are running IBM i 7.2 OS.

2) Prompt the CHGSMTPA command with a F4 to change your SMTP attributes.

3) Configure the "SMTP domain alias" (ALIASDMN) attribute to the e-mail domains you wish to use on your FROM e-mail addresses.

• Example: CHGSMTPA ALIASDMN('US.IBM.COM' 'CN.IBM.COM')

• Example: FROM: as400@us.ibm.com TO: as400@us.ibm.com

While logged in as the AS400 user profile, I executed the command, SNDSMTPEMM RCP((as400@us.ibm.com)) SUBJECT(TEST) NOTE(TEST) - This e-mail will be delivered locally since the from and to e-mail addresses are identical.  If you want this scenario to flow through your Forwarding Mailhub Server, you will need to implement the QIBM_SMTP_FWDSVR_LCL_MAIL=YES environment variable as discussed in the URL, https://www-01.ibm.com/support/docview.wss?uid=nas8N1010638.

4) If a SMTP user does not exist for the IBM i user profile, execution of the ADDUSRSMTP command or WRKSMTPUSR Option 1 to "Add a User" is required. If a SMTP user already exists, execution of the CHGUSRSMTP command or WRKSMTPUSR Option 2 to "Change a User" is required.

• Example: ADDUSRSMTP USRPRF(as400) ALIAS(as400) DOMAIN(001 *DFT)

• Example: CHGSMTPA ALIASDMN('US.IBM.COM' 'CN.IBM.COM')

Domain index 001 = US.IBM.COM and index 002 = CN.IBM.COM
ADDUSRSMTP USRPRF(as400) ALIAS(as400) DOMAIN(002 *DFT) = This will set a SMTP alias of "as400@CN.IBM.COM" as the user's FROM e-mail address since the domain index 002 equates to CN.IBM.COM.

5) Execute the command WRKSMTPUSR Option 5 to work with your SMTP users and verify the alias e-mail address configured.

1) Execute the WRKDIRE CL command to work with directory entries.

2) Locate the user ID in the list you wish to customize the FROM e-mail address for.

3) Enter option 2 next to the user ID to change the directory entry.

4) Press F19 to change the name for SMTP. NOTE: You might have to press ENTER if you are setting up a SMTP name for the first time.

5) Set the SMTP user ID and domain to your desired values to construct the FROM e-mail address.

SMTP user ID = the user information specified to the left of the @ symbol.
SMTP domain = the e-mail domain specific to the right of the @ symbol.

Example: SMTP user ID = as400; SMTP domain = us.ibm.com
These values will customize the FROM e-mail address to "as400@us.ibm.com" when sending email under the directory entry user ID.


 

6) Press ENTER twice to save the SMTP name and directory entry changes. With the above configuration, any e-mails sent by the AS400 user profile will have a FROM e-mail address equal to the <SMTP user ID>@<SMTP domain> value, which happens to be "AS400@US.IBM.COM" in this example.

7) All of the changes are dynamic and take affect immediately. A restart of the SMTP Server is NOT required.
