Sorry for the brevity here but I woke this morning to find my mailserver sending 1000+ rejected email notices to postmaster@, and it was increasing by the minute. I have shut down Sendmail and am removing all relay permissions (I hope) but have a few issues that need to be resolved quickly before going back online - knowing the spammer will be retrying and my legitimate users are losing services.
1. There are 700+ emails sitting in the outgoing queue, I am using WebMin to delete them but at 20 at-a-time it is useless. I need a command line that will do it without causing more damage.
I guess the fastest way is to simply delete everything under /var/spool/mqueue.
2. MySql is shut down for some reason, I don't know if it's related to the attack. "service msqld status" returns "msqld dead but subsys locked"
Well you could check the mysql logs to see if it gives you any clue about what might be wrong...
