Buildbot (from buildbot.net) : iCloud email not working as Status Target

I am setting up buildbot to use an iCloud email address as Status Target : 

m = mail.MailNotifier(fromaddr="[email protected]",
                  sendToInterestedUsers=False,
                  extraRecipients=["[email protected]"],
                  useTls=True, relayhost="smtp.mail.me.com", smtpPort=587,
                  smtpUser="[email protected]", smtpPassword="some_icloud_password")

(the iCloud email setup instructions are here).

Seems like there's something wrong with the TLS/SSL handshake (from master/twistd.log) :

Note : I am NOT able to send email from the command line via "mail" or "sendmail" - I didn't bother since I noticed buildbot has its own email client Python code.

Please help - thank you !

Solution

  • Solved it : since buildbot uses virtualenv, I needed to install pyOpenSSL via easy_install - in the directory that contains the local python env (i.e., the "sandbox") I ran "easy_install pyopenssl" and the SSL handshake proceeded correctly, so buildbot can send emails now. Initially, I "installed" pyOpenSSL by linking to the SSL directory from inside the system Python framework. Looks like the buildbot install script doesn't install pyOpenSSL, weird. Thank you !
