APAR status

  • Closed as program error.

Error description

  • The customer has ATSIGN set to B5.  A command is received with
    the lowercase text "mail from:" in the header.  After
    conversion to code page IBM-273, the AT sign in the path name is
    x'B5',  With ATSIGN=B5, this should get changed to x'7C'.
    However, a code defect prevents the ATSIGN replacement if the
    first 4 bytes of the header is not in uppercase
    (e.g. "MAIL FROM:").
    This causes that path name verification to fail with rc=11:
    03/08 10:35:51 TCPCSMTP ERROR
    :026:mlJesVerifyPath:Path='<userid||x'B5'||hostname>' rc=11
    

Local fix

  • Use uppercase headers such as "MAIL FROM:" and "RCPT TO:".

    * PROBLEM DESCRIPTION:                                         *
    * CSSMTP ATSIGN function does not work correctly with          *
    * lowercase SMTP commands in a mail message.                   *
    ****************************************************************
    * RECOMMENDATION:                                              *
    * Apply PTF.                                                   *
    ****************************************************************
    When CSSMTP processes a mail message which has matched
    configured AtSign symbol in it, a check is performed to compare
    the SMTP command "MAIL FROM" or "RCPT TO" with the uppercase
    only. The configured AtSing symbol in the mail message is not
    converted into the standard IBM-1047 "at sign" symbol, the mail
    message is rejected.
    

Problem conclusion

  • CSSMTP is modified to allow the matched configured AtSign symbol
    in mail message being converted into the standard IBM-1047 "at
    sign" symbol regardless if the SMTP commands are in uppercase or
    lowercase characters.
