Hi, I've just upgraded a server from OpenBSD 4.4 to 4.6, and qmail-ldap stopped working, throwing tons of the "CNAME_lookup_failed_temporarily" errors. I recompiled everything, but nothing changed.
Then I added "ulimit -c 204800" to qmail's startup script, and about three quarters of the deliveries started to work. So I thought I'd actually solve the problem and bumped the packet size to 64k, as suggested by Henning in his LWQ guide, but some domains still fail, despite having reasonable DNS setups. Eg. for hzw.ltindia.com, I can do successful DNS lookups right on the affected host, using the same name server as the qmail-ldap installation, but the logs still hold the CNAME error. I can prove that these errors didn't occur on OpenBSD 4.4. Does anyone have a quick idea about solving the problem? TIA! Kind regards, --Toni++
