Details

sendmail through at least 8.14.7 allows SMTP smuggling in certain configurations. Remote attackers can use a published exploitation technique to inject e-mail messages that appear to originate from the sendmail server, allowing bypass of an SPF protection mechanism. This occurs because sendmail supports . but some other popular e-mail servers do not.
