My SMTP server doesn't recognize the @ character in my e-mail addresses. How can I send mail?
The @ characteris defined as EBCDIC x'7C' in most but not all OS/390 codepages. The SMTP Server uses the @ symbol to separate the local part from the domain in e-mail addresses and expects the @ symbol to be x'7C'.
A recent fix to CommServer, PQ36249, addresses this issue allowing a different character to be used as the @ symbol.
