Hello, This has been my first successful setup of a Buruwa front-end server. This has also worked well with everything in place for a couple of weeks. Although, I have had a nagging problem that SEEMS to stem from Greyfix. Let me mention that this is the first time I have gotten this to work as well. With all that being said, I would like to fix the issue and not disable Greyfix, if possible. Setup VM on VMware ESXi 5.1 Ubuntu 12.04 LTS Mailscanner 4.84.5-3 Greyfix 0.3.9 Baruwa 1.1.2-4 Postfix 2.9.3 Code: Feb 11 09:04:41 spam1 postfix/spawn: warning: /usr/local/sbin/greyfix: process id 25350: command time limit exceeded Feb 11 09:04:41 spam1 postfix/spawn: warning: /usr/local/sbin/greyfix: process id 25353: command time limit exceeded Feb 11 09:05:20 spam1 postfix/smtpd: warning: problem talking to server private/greyfix: Connection timed out Feb 11 09:09:35 spam1 postfix/smtpd: warning: problem talking to server private/greyfix: Connection timed out Feb 11 09:09:35 spam1 postfix/smtpd: NOQUEUE: reject: RCPT from unknown[22.214.171.124]: 451 4.3.5 Server configuration problem; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<support.whissa.us> Feb 11 09:43:52 spam1 postfix/smtpd: warning: connect to private/greyfix: Resource temporarily unavailable Feb 11 09:43:52 spam1 postfix/smtpd: warning: problem talking to server private/greyfix: Resource temporarily unavailable I am also receiving 'Other Bad Content Detected' subject messages with this in the information section: Report: MailScanner: Message attempted to kill MailScanner This whole process seems to lock up the entire machine. After logging into the machine I am able to type reboot now but nothing happens. I have to do a hard shutdown and after the machine comes back up I run this: Code: cd /var/lib/greyfix/ /etc/init.d/postfix stop rm __db.00* /etc/init.d/postfix start Postfix main.cf Code: smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unknown_recipient_domain, reject_unauth_destination, check_client_access hash:/etc/postfix/whitelist_ip, whitelist_policy, grey_policy, reject_rbl_client b.barracudacentral.org, reject_rbl_client zen.spamhaus.org, reject_rbl_client bl.spamcop.net, permit smtpd_data_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_pipelining smtpd_restriction_classes = grey_policy, whitelist_policy grey_policy = check_policy_service unix:private/greyfix It seems to run fine for the next couple of days and then it starts all over again. I am not sure that I am on the correct path with Greyfix being the problem. After searching around I see that it may be clamav as the issue but I do not see anything indicating that in the logs. Any help is appreciated.
