Stunnel Setup Doc updated

I’ve upgraded to the latest version of Stunnel, 4.15, and changed some of the services that make use of Stunnel. The version upgrade also allowed me to make some changes to how I configure Stunnel on my machines. You can find the updated doc here.

New version of qregex patch available

The latest version of qregex (20060423) adds the LOGREGEX environment variable. Set it, and the matching regex will be included in the logs generated by qregex; good for testing regex patterns or if you want to collect stats on how your regexes are performing. Get qregex here.

Bug found in version 20050523 of my starttls-2way-auth and qregex-starttls-2way-auth patches

Remote authentication was not working in the 20050523 version of these patches. This problem has now been resolved. Thanks to Jochen Schlick for bringing this issue to my attention. You can find updated patches here. Since I needed to create new versions of these patches anyway, I’ve also updated them with the latest version of Frederik Vermeulen’s netqmail-1.05-tls patch, 20060104.

Serious bug found in starttls-2way-auth-20050127.patch and qregex-starttls-2way-auth-20050127.patch

It has been brought to my attention that there is a serious bug in these two combination patches. The bug can result in mail being lost in the event of a temporary (400 series) error occuring during mail delivery to a remote server. The bug can also prevent non-delivery notifications from being sent to the sender when a permanent (500 series) error occurs. These problems occur only when smtp authentication is not used when sending email. Receiving email is not impacted. Older versions of these patches may also be affected but I haven’t tested them to be sure. I’m currently testing new versions of my patches that correct this bug. If you are using any version of the qregex patch, then you’re safe. The bug only impacts my combination patches. If you want to help me test the fix, drop me a line.
