dovecot + antispam + sendmail
Whats a good antispam solution? I am using sendmail and dovecot 1.1. I came across dovecot's antispam plugin, but it seems it does not support 1.1 yet. I am also looking for something non-perl based. I am already doing some greylisting with sendmail milter. Any other good suggestions? If not, I guess I might have to downgrade back to 1.0 dovecot. Thanks

Postfix setup
I'm trying to clarify the various ways in which I could set up Postfix + Dovecot + SpamAssassin under CentOS-7, and I'd welcome any comments on the following remarks. As far as I can see there are 3 standard ways of setting this up: 1. Use amavisd 2. Use dovecot + pigeonhole/sieve 3. Use spamass-milter At present I'm following (2), but am thinking of going over to (1), since

Antispam only when LMTP delivers some specific messages
Hello, we're setting up a weird platform where every incoming email is passed from the MTA directly to a tool that then uses dovecot LMTP to deliver the message into the user mailbox. We are legally *not* allowed to run antispam on all the incoming messages, but only on some of them, as they are recognized by the aforementioned tool; but given that tool directly uses LMTP to delivers the

Postfix , Dovecot & the Spam fight
Hi, I'm currently busy with a substiution of my current mail server. I'm currently using * Clam-SMTP and * SpamAssassin to fight Spam. I wonder if it is worth implementing AmaViS with SpamAssassin backend instead and also using AmaViS to speak to clamd directly. But I more and more wonder wether AmaViS is even worth it?! It currently looks to me as if AmaViS is eating LOTS of

Up to date guide/information Sendmail SMTP Auth
Hello all, I've been googling my brains out since yesterday looking for up-to-date information on this matter, and have found information that is anywhere from 15 to 5 years old. I'd really like some information that much more up to date on the subject. Specifically configuring Sendmail SMTP authentication (_no smart host stuff_). I've got Sendmail 8.14 installed on a CentOS 7.3

Quota status to postfix in distributed environment
Out of curiosity would it be possible to configure dovecot in such a way that if a message had been accepted by postfix because it couldn't check quota the message was delivered anyway, despite being over quota? I'd much rather that then risk backscatter. (I used to have quotas, but with the size of disks I've found it easier to simply have a "clue bat?approach and a reasonable

Use postfix and spamd on CentOS 6 - looking for a shortest guide
Hello fellow CentOS-users, on the net there are lots of Spamassassin related HOWTOs - describing how to create a shell script for Postfix and how to install Spamassassin and start its spamd daemon - step by step. Additionally antivirus setups are described... But I have a strong feeling, that this is unneeded on CentOS 6 - because there are already preconfigured stock packages for postfix and

Roaming Profiles
I'm mulling over the idea of replacing my Win 2k MS AD using Samba. But I'd like to retain roaming profile capability for all my users. Based on your experience is it stable enough to implement for a production environment? I have only 30 using Win 2k Pro and some XP. What are the pit falls I need to look out for? Thank you! Joe

Remote system up/down monitoring tool?
I have a small number of boxes in different locations, and currently have a fairly crude cron job running on each, which does a ping of one or more of the other boxes, and if the ping fails, it emails me to say the other box might be down. It then emails me again the next time the other box appears to be up. Of course, this can't distinguish between the remote box really being down and there

Disabling Spamassassin on outbound email
Does anybody have a good method for disabling SA checks on outbound email under sendmail running the spamass milter? Some of our Vhost accounts are getting flagged as spam on the way out due to being on a dirty ISP network. John Hinton

Spamassassin as root and pyzor
I've just set up a new mailserver using Centos5.2 (sendmail+clamav-milter+spamass-milter). I'm using the spamass-milter package from rpmforge (spamass-milter-0.3.1-1.el5.rf). I notice that the default setup is to run it as root. I set up my previous mailserver on Centos4, and I can't remember if I did anything special, but on that machine it runs as user "sa-milt". Is

sendmail and spamassassin
I have a problem getting spamd and sendmail (both stock CentOS4 rpms) to work together on a couple of smtp relay machines. This is clearly a configuration issue and no doubt revolves around my lack of comprehension of how this is to work. Basically, the setup consists of two frontend public smtp transports that redirect all email through a firewall to an internal imap server for final

Oen source IP phone, maybe?
Its another one of my "If I only had time...damn this sleep thing" ideas, but I really wonder how hard/cost effective it would be to build an open source IP phone or phone adapter (ala ATA). In about 20 minutes of mulling and research, I figure you could do it for about $40 in parts plus coding time... 1 DS80C400 Ethernet enabled microcontroller with built in IPV4/V6 stack $10 1
