Both of my Solaris sendmail gateways started to have some problems since
Oct.14 when the "Possible SMTP attack: command=HELO/EHLO, count=3" appeared.
- Sendmail stops repsonding for a short time then came back, this happens
several times a day
- milter-greylist process died, then it came back on by itself in about 5
minutes, this also happens serveral times a day
- I can't fine /var/milter-greylist/milter-greylist.sock on one of my two
servers, should I copy this file over? (It's size is zero and has a special
permission settings srwxr-xr-x)
Some error messages (random picks, not in any orders):
milter-greylist: [ID 552762 mail.error] greylist: accept() returned
invalid socket (Too many open files)
milter-greylist: [ID 879519 mail.warning] greylist: setsockopt() failed

SW Versions:
Sendmail 8.12.10
mimedefang version 2.51
SpamAssassin version 3.0.3
running on Perl version 5.8.0
milter-greylist: I'm not sure what version it is, help!..
I'm new to this environment, I take over from a previous sysadmin who left
so I am desperate here...
I think about upgrading, but affraid to break things up. I have clone one of
the gateways to a 3rd server and able to do testings on it.
Please help!
