Milter-greylist

Hi,

I've recently noticed I get a lot of these errors on mail servers:

Dec 17 17:00:14 server sendmail[29303]: oBH6011k029303: Milter (greylist):
timeout before data read
Dec 17 17:00:14 server sendmail[29303]: oBH6011k029303: Milter (greylist): to
error state

and later on:

Dec 17 17:00:17 server milter-greylist: oBH6011k029303: skipping greylist
because sender is SPF-compliant, (from=<blah@...>,
rcpt=<blah2@...>, addr=blah.somesevrer.com[xxx.xx.xxx.xx]) ACL 1414

I've tried trouble-shooting what the problem could be, spent some hours on it
but can't figure it out.

I'm running milter-greylist 4.3.5 and 4.3.8 on various mail servers. I'm
slowly upgrading to 4.3.8 as time permits.

This "to error state" error happens on all machines.

I run Scientific Linux 5.5 (RHEL 5.5 derivative) on these mail servers, so use:

sendmail-8.13.8-8.el5.i386

I compile the RPM's of milter-greylist from the SPEC file.

The user I use for milter-greylist is:

smmsp

with the process being:

10229 ?        Ssl    4:04 /usr/bin/milter-greylist -u smmsp -P
/var/milter-greylist/milter-greylist.pid -p
/var/milter-greylist/milter-greylist.sock

and the relevant directory being:

# pwd
/var/milter-greylist
# ll

srwxr-xr-x 1 root  root       0 Dec  4 20:49 milter-greylist.sock

I've checked various items and can't find where it's failing.

I thought it had to do with the root:root permissions on the socket above,
maybe they had to be smmsp:smmsp ? but I can't seem to change that particular
permission when the milter starts up.

I've run it in verbose mode, but that doesn't help. I've run it in debug mode
(with -v) and that didn't show anything extra either.

The /etc/mail/greylist.conf file passes syntax.

Any ideas how I can trouble-shoot this problem?

Note I've been running milter-greylist for many years and it's always worked
flawlessly on these machines.

Thanks.

Michael.
