The problem is their SMTP server is taking its own sweet time recognizing the end-of-message sequence, so peer MUAs are starting to timeout instead. Here is a manual session: [EMAIL PROTECTED] ~ $ telnet sita.openmoko.org smtp Trying 88.198.124.203... Connected to sita.openmoko.org.

There are issues with their DNS, as this validator shows: http://www.dnsstuff.com/tools/dnsreport.ch?domain=openmoko.org with the biggest problem being stealth NS records with leakage, which can wreak havoc with timeouts.
