Hi, folks. I'm senior online editor at CIO.com, and I'm working on an article for which I'd very much like your help. There's often a lack of communication between techies and top company management. Maybe they don't want to hear about problems; perhaps you give them technical details that are far more granular than they want to know. But dealing with spam is a topic

I'm setting up a Postfix and Dovecot combination. What I want to do is have a user database that (1) is not running from some engine (so not LDAP or SQL or such) ... and (2) is completely disassociated from system users (e.g. most email users are not in /etc/passwd and most /etc/passwd users are not email users). Ideal would be a one-file solution, which can be managed by text editing or

I have recipient_delimiter = + in main.cf (Postfix). But deliveries to dovecot/deliver are still being rejected. It appears that the full email is still in the envelope (e.g. phil+howard at example.com which I want to be delivered to phil at example.com). Is that how it's supposed to work and Dovecot just doesn't support this?

I'm looking for an IMAP testing tool, suitable to use with Dovecot IMAP. It needs to support TLS, STARTTLS, and login/authentication. It needs to be able run from command line, shell scripts, and even do so under cron jobs (e.g. a way to supply the password to use w/o a terminal prompt). Typical interactive mail clients just don't cut it (even the text mode ones). One reason is I need

Hello, Today I searched redhat official portal and learned that Sendmail is considered deprecated. By default, CentOS 7 will use postfix as MTA. I need good advise on what it means to us. We are CentOS customers. We use that operating system for quite a few years. We rely on Sendmail for years for us to relay large quantity of emails to our customers for marketing purpose. We build our additional

I have this in dovecot-postfix.conf: mail_location = maildir:/home/mail/dnamesum=%12MLd/dname=%Ld/unamesum=%12MLn/uname=%Ln/mail Yes, it is excessive, but that's just for testing. The pattern I really want is less clear for debugging. In postfix/main.cf I have: mailbox_command = /usr/lib/dovecot/deliver -c /etc/dovecot/dovecot-postfix.conf -a "${RECIPIENT}" I verified through

I suspect this is a user agent issue, given that Evolution is flaky in so many areas. When I deliver mail to a subfolder/subbox (e.g. the -m option in the deliver command), and Evolution doesn't know of it, yet, creating it fails, and Evolution still can't get to it. Doing things the other way around (create it in Evolution first, then deliver to it) works fine. Seems to be silliness to

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

What makes Postfix superior in fighting spam? How do I integrate MIMEDefang, SpamAssassin, and ClamAV with Postfix? Are there migration guides for moving one's Sendmail anti-spam and AV

Just having another look at http://wiki2.dovecot.org/MailServerOverview , it seems to have some statements in it which are misleading, and some which are really ... well ... wrong. Quote: "With the possible, optional, exception of the deliver MDA, Dovecot is not involved with reception, delivery, and storage of mail. That function is provided by a MTA such as postfix

Is there a tool equivalent to the system "passwd" command (or maybe "adduser" or "useradd") that can support a passwd-file by setting a password, encrypting it with the salted MD5 scheme? The system "passwd" command doesn't have an option to "do it to this alternate file instead of /etc/shadow".

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 The list server at shorewall.net is seeing a small but steady stream of quaranteened messages from anti-spam software that is asking the list server to respond and thus register itself as a legitimate source of email. I also receive these requests personally. Here''s an example: -

I like this unofficial survey of hardware but wondering what MTA and spam filtering everyone is using. I do front end spam filtering for other servers as well.

Hello all, I've been trying to get spamassassin and clamav working, but got really confused when I realized there are various incarnations of the software. Originally, I started out with just spamassassin, but learned there is also an SA-milter. Can someone tell me which of the various spam fighting packages i.e., sa, sa-milter, clamav, clamave-milter, and so forth? I ran into
