VERP/GSOC Progress Report

GSoC Project Progress Report
Community Bonding Period

I was active in the Wikimedia community since November 2013, so I concentrated on getting more feedback on the project -- specially the shift from PHP/ Pear mailer to third party software - Swift mailer. The shift requires a lot of consience and I kept on getting feedback, through Wikitech-I and the bugzilla report. Details of the mails are attached below. I had already started building the project environment by March 2014 with help of Jeff and legoktm, so was polishing on its working -- porting it to wikitech labs ( under project name: mediawiki-verp ).

March 2014

 * 1) Built local instance of Wikimedia Email-Web server model.(https://www.mediawiki.org/wiki/VERP/MicroTasks )
 * 2) Model consisted of two virtualboxes, Box1 (runing exim4 and MW core) sending emails via Box2 (running postfix).

April 2014

 * 1) Modified test environment: box1 has MW running -> sends the email -> intercepted by box2 -> routed to Box2 /var/mail/root. Box2 has external connection via NAT.
 * 2) Box2 rejects the mail, Box1 exim produce the bounce to wiki@wikimedia.org in /var/mail/wiki

Week 1 and 2: May 1 to May 19
Week 3 : May 19 - May 26 Week 4 and 5 : May 27 - June 7 Week 6 : June 9 - June 15
 * 1) Shifted the above local instance to WikiTech labs ( under project mediawiki-verp ). box1verpnop sends the mail having box2verpnop as the smarthost which rejects all mails to wiki@wikimedia.org. The bounce is created by box1 in the /var/mail/root of box1verpnop.
