Description Jan Kohnert 2012-06-10 11:39:06 UTC 
I found an error in the fail2ban configuration files for sending a mail after an action via sendmail.

To set the Mailheader Date:, it simply uses the date-command. Unfortunately it does not ensure the system locale to be C, or equivalent, so the send date can be invalid depending on the system locale.

The attacted patch fixes the situation by explicitly setting the locatle the "C" when calling the date-command.

Reproducible: Always

Sorry, forgotten input, but there it goes:

b079 ~ # emerge -pv fail2ban

These are the packages that would be merged, in order:

I can confirm this bug for LC_TIME=de_DE.UTF-8 locale. I fixed it by switching from sendmail-whois to mail-whois action. The latter does not set the date header manually.

Shouldn't the patch set LC_TIME variable instead of LANG?
