Gmail filters and rss2email

Thursday, August 12th, 2010 at 11:33pm

After seeing that external mail was being delivered correctly to my Google Apps domain, I changed my rss2email config to deliver to Google Apps instead of directly to the local mailbox.

When filtering with procmail you can filter on anything you want, but in most cases a few regexes will get you what you need. In contrast the filtering options in Gmail are extremely limited. There are a couple of headers you can match against, and then just a simple string match.

I was able to tweak rss2email to add the URL of the RSS feed as the List-Id header. I can then setup a filter for each RSS feed. Again, like forwarding addresses, I monitor a lot of RSS feeds. Over 120 which means I will also need over 120 filters just for RSS feeds.

What would work is for the RSS feeds to be categorised before I send out the emails, I then only need a filter per category. An additional benefit is that when another RSS feed is added, a new filter is not required.

As I am considering further modifying rss2email (or replacing it completely), what else could I do?

Something that I don’t like about Gmail (and certain other mail clients) is that the message lists display the time the message was received by Google, not the time it was sent or the time in the message headers. This means that the RSS messages are clumped together because the script only runs once every few hours.

This cannot be changed as long as the messages are delivered via SMTP. But, thanks to a small project at work, I know that if I were to write the messages in directly via IMAP, the dates will be what I want.

If I were writing the messages in via IMAP, filters will not be run, but writing the messages directly to the appropriate label means that the filters are not even needed. I would have no idea how to modify rss2email to use IMAP, so I would be writing my own solution from scratch.

This method of direct injection via IMAP is also how my identi.ca/Twitter/Facebook updates should be delivered. In this case I indend to write something that uses the appropriate API, not the RSS feed as is the case for identi.ca and Twitter. I already use the API for Facebook, but only to produce an RSS feed that is then picked up by rss2email. It is a bit convoluted, bit it has worked.

  1. Care to share how you configured rss2email for local delivery?

    I too have the remote delivery working, but would rather bypass gMail as they have a ~500 email / 24 Hr “limit”.

    Thank you for your time.

  2. I got the localmail part worked out. I just need to figure out the config.py for local delivery. Progress!
