The newest update of Mac OS Yosemite (10.10.4) is reported to have broken sending email. Many Yosemite users are reporting that they can no longer send mail via simple mail transfer protocol (SMTP, locally smtpmail.jlab.org) or SMTP over SSL (smail.jlab.org). The latest update Apple published yesterday is said to have caused this problem.
