[lug] imap hacking?

[Rob Nagler]

Someone was visiting all my servers trying to hack my imap ports.
They didn't get in, but I'm wondering if there's a new attack out
there.

It's coming from a dial in in Germany.  Here's a sample of entries:

Jul 14 08:58:43 my-host imapd[5653]: Login failed: no CRAM-MD5 entry user=web auth=web host=pD9524D51.dip.t-dialin.net [217.82.77.81]

I'm running imapd-2001a-1.72.0 for RH 7.2, which was last updated on
4/25/02. 

Thanks,
Rob
