Problem summary
**************************************************************** * USERS AFFECTED: * * All users of the IBM Communications Server for z/OS Version * * 2 Release 1 and Version 2 Release 2: CSSMTP * **************************************************************** * PROBLEM DESCRIPTION: * * New function to add a TLSEhlo option to the CSSMTP * * configuration file. * **************************************************************** * RECOMMENDATION: * * Apply PTF. * **************************************************************** RFC3207 (SMTP Service Extension for Secure SMTP over Transport Layer Security) specifies that sending an EHLO SMTP command is optional for a SMTP client after a successful TLS negotiation. However, some SMTP servers require an EHLO command after a successful TLS negotiation.
Problem conclusion
CSSMTP has been modified to add a TLSEhlo parameter option to the configuration file. The user can specify TLSEhlo Yes on the configuration Options statement to request CSSMTP to send an EHLO command after a successful TLS negotiation.
