Yahoo Mail

9th September 2010
Yahoo mail = fail. Can't wait for this shit service to just die.
Their web interface is horrific, their anti-spam engine misses too much stuff and some times my emails don't reach their recipients (false positives on their part probably) or they hit the inbox severely delayed (I noticed sometimes it can take up to 24h, even more).
Whoever reads this message and is using Yahoo email service: STOP. IT'S JUST NOT RELIABLE.

Here's to Davmail

12th September 2010
Cheers to the DavMail devs for making my life bearable.
For those of you standard protocols lovers stuck in an Exchange environment this might be of interest:
DavMail is a POP/IMAP/SMTP/Caldav/Carddav/LDAP exchange gateway 
allowing users to use any mail/calendar client 
(e.g. Thunderbird with Lightning or Apple iCal) with an Exchange server,
even from the internet or behind a firewall through Outlook Web Access.

DavMail now includes an LDAP gateway to Exchange global address book
and user personal contacts to allow recipient address completion
in mail compose window and full calendar support with attendees free/busy display.
Enjoy!

Listing your own customers in Spamhaus RBL

13th September 2010
Recently I had problems with a web server denying connections (HTTP error 406) from a certain IP address.
At first I thought it was because of some wacky firewall or tcpwrapper rule.
I couldn't be more wrong - It was mod_security verifying the remote IP against Spamhaus RBL...
While it may seem like a good idea at first, turns out it is not:
1. Because it slows down the request (as Apache has to lookup IPs against the RBL all the time).
2. Some IPs are in a RBL for the wrong reason.

As it turns out that particular IP belongs to BT,
and BT in their infinite wisdom decided to list in Spamhaus a good part of their IP space... Cool, huh?
More info here (and a screenshot for posterity here).
You got to love the corporations!
