Lotus Domino Release 5.0.2c (Intl) ESMTP Service on OS/2 Warp 4.5
Earlier versions of the ESMTP service can be vulnerable. ESMTP service on
other operating systems can be vulnerable as well. This has not been tested.
When opening a connection to the SMTP service and filling the arguments to

the mail from denial-of-service vulnerability reported in
The service will also crash when the command mail from receives an
argument on a size of 4096 chars but that is a known vulnerability.
