Amazon SES – “Illegal Header” errors
My thoughts on the “illegal header” error some people are encountering when relaying mail through postfix/SES. Plus some perl code that should help fix it.
Integrating Amazon Simple Email Service with postfix for SMTP smarthost relaying.
How I configured an EC2 instance to relay mail through Amazon’s SES, and some of the bumps I encountered along the way.
Autodiscover mysteriously stopped working (Exchange 2010)
TweetI had Autodiscover working for months but recently it just stopped. I’m not sure why, but it may be related to removing the last Exchange 2003 servers from service recently. Maybe some setting got wiped from AD when I uninstalled Exchange 2003 (as per the procedure Microsoft gives). Basically what was happening was that the [...]
Relaying through Google Apps using Sendmail to bypass EC2 spam blockage
TweetUpdate 3 May 2011: I’ve subsequently modified our EC2 systems to relay SMTP mail through Amazon’s SES which doesn’t have the 500 messages per day limit that Google Apps does.

Wasted time with Exchange 2010, SquirrelMail, and IMAP-SSL
TweetI’m setting up SquirrelMail to point to my Exchange 2010 server via IMAP (don’t ask) and couldn’t get SM to talk to Exchange on port 993 (imaps). Even though the servers on the same subnet, any time passwords are being sent over the network I like to opt for SSL. I found a couple of [...]

I wasn’t part of the Sysadmin team at that point but I know they had to restart SpamAssassin relatively frequently, manually clear out the [...]
Long email signatures amuse me.
TweetPutting a glossary in your emails is a new one for me. Not really a bad idea if you deal with lots of industry-specific terminology and lots of non-industry people.

Outlook 2007 & Exchange 2010 Autodiscover SSL certificate error annoyance
TweetOne of the more annoying side effects of migrating my mailbox to Exchange 2010 has been the nagging of Outlook 2007′s Autodiscovery feature. Now, every time I start Outlook I get hit with a certificate error for autodiscover.domain.com. Now, autodiscover.domain.com is a CNAME to mail.domain.com, which is the OWA URL for the CAS. The SSL [...]
