Code page enhancements for CSSMTP

z/OS® V2R3 Communications Server, with APAR PI93278, is enhanced to support multi-byte character sets with the Communications Server SMTP (CSSMTP) application. This enhancement allows migration from SMTPD to CSSMTP for customers that use multi-byte character set code pages, and provides improved code page support for characters in the mail subject line.
