Code:

# telnet name-of-server 25
helo
mail from: sender-email@address
rcpt to: receiver-email@address

look for more info Test mail server

Hi,

Your server was used to send out spam. Check the logs to see how it was done
Also use this to see if it's an open relay.

You should find who started sending the mails in queue. Run:
Code:

egrep "o9GClPVv003757|o9GClPVx003757|o9GClPVx003757" /var/log/maillog |grep "from="
to find the IP of the offender.

Meanwhile. stop sendmail and delete them, so it stops trying to send them out.

This result is based from the logs posted in your 2nd post

You should check how this guy abused your mailserver by examinig thoroughly your logs for his IP.
And once again you should check here if your mailserver is an open relay

To remove spam from the queue, I suggest you to stop sendmail and delete everything in /var/spool/mqueue and /var/spool/clientmqueue and then restart sendmail.
If you are afraid that you may delete legitimate mail, you can use this perl sciprt

Hi,

I don't know what your alternate server is, but you should search to see how the spammers managed to use your mailserver(s).
Only doing so you will stop them sending out spam. If you don't stop them, you'll be soon blacklisted by the various RBLs and you will not be able to send legitimate mail also.
You didn't answer if you check to see if your mailserver(s) are open relays, or if you found any evidence on how they succeeded to send spam through your server.

Regarding clamav, I guess you have to upgrade to a newer version and then run freshclam to update the virus databases.

WARNING: You must specify at least one database mirror in /usr/local/etc/clamd.conf

thanks

You didn't get any spam at the beginning.
You (your mailserver) was used to send out spam.
And you still insist on not telling us if you found what happened and rectified it.

Quote:

WARNING: You must specify at least one database mirror in /usr/local/etc/clamd.conf
Edit /usr/local/etc/freshclam.conf and make sure you have
Code:

DatabaseMirror database.clamav.net
If freshclam still complains. comment out this line and use:
Code:

DatabaseMirror db.in.clamav.net
as it looks you're coming from India.
