Professional Developer

The Professional Developer is a 360 degree feedback tool which I took on as a partially-completed project in May 2008 and finished for August 2008. The tool allows administrators to survey groups of users in team-dynamic areas and presents customized analysis.

Mails bounced from PHP on OS X 10.5 Server

admin — Wed, 01 Apr 2009 06:02:13 +0000

Found a nice little kicker today. At some point in the past few months, CUIT reconfigured their mail servers to only accept mail with a proper “MAIL-FROM” header response. Also, at some point (probably last year when we upgraded the box to 10.5 Leopard), Apple decided that it would be wise to switch the “www” user to have the primary name “_www” instead. Makes it less ambiguous if you had an OD user with the name “www”, but since all of my usernames are of the format of two to three letters and then at least one digit, it’s not a problem.

The result?
Apr 1 00:50:39 projects postfix/smtp[393]: 21386ACF69A: to=<*****@columbia.edu>, relay=external-smtp-multi-vif.cc.columbia.edu[128.59.48.6]:25, delay=0.98, delays=0.68/0.24/0.03/0.03, dsn=5.7.1, status=bounc ed (host external-smtp-multi-vif.cc.columbia.edu[128.59.48.6] said: 554 5.7.1 Bad sender address (in reply to end of DATA command))

Basically, no matter what I told PHP to use for sendmail_from, at some point, postfix was just setting it to _www@. A quick and easy solution:

Open Workgroup Manager.
Authenticate to the local directory (pick “Local” from the dropdown)
Go to Preferences, and select “Show ‘All Records’ tab and inspector” if not already checked.
Click on the “all records” tab (next to computer lists, looks like bulls-eye)
Select “Users” from the dropdown, then _www from the user list
Delete the “RecordName” value _www, leaving just the “www” value (if _www is the only one, then just rename _www to www).
That’s all!

Your mileage may vary, etc. but since I couldn’t find anything on google regarding this error, thought it would be nice to share.

SEAS Portal

The SEAS Portal supports students, faculty, and staff at a number of departments in Columbia’s School of Engineering and Applied Science. It provides “one stop shopping” for job posting, file sharing, survey provisioning, and alumni tracking.

CUSearch09.com is a companion website to a campus-wide photo scavenger hunt that took place at Columbia University in Spring, 2009. Players used the website to register for the event, upload their photo submissions, and view their scores. Judges used the website to efficiently judge all of the photos.
