spam control
Gents,
I have added the following to /etc/mail/sendmail.mc and rebuilt it
trying to control spam. I still get about 25 spam messages a day.
Is there something else that can help control spam?
Thanks

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

Using Dovecot-auth to return error code 450 (or other 4xx) to Postfix when user is on vacation
Hello to all members.
I am using Dovecot for 5 years, but this is my first post here.
I am aware of the various autoresponder scripts for vacation autoreplies (I am using Virtual Vacation 3.1 by Mischa Peters).
I have an issue with auto-replies - it is vulnerable to spamming with forged email address.
Forging can be prevented with several Postfix settings, which I did in the past - but was forced

Quota, maildir, MySQL,
Hi everybody,
I am trying to work with quota. I use postfix and dovecot with a sql
backend. Below you'll find my configuration. Everything works except for
the quota part. It doesn't seem to see the quota and doesn't respond to
the sender that the client is over its quota.
versions:
postfix-2.5.20070531-mysql
dovecot-1.0.2-mysql
Thanks for the help in advance.

Q's about switching from sendmail to postfix
Running CentOS 4.2 with all updates. I've been using sendmail for my
MTA since forever. I've grown used to it and I can make it do what I
want it to. However (there's always a catch, isn't there)...
Lately it seems that some mail is being lost. I've noticed some
instances when a message was sent to myself and others which I will only
see if someone replies back to

Sendmail
I know this is a "generic" question, but fully CentOS related. I
attempted to set up i386 v.4.1 on my primary computer at the co-located
site, and thought I had everything squared away till I discovered the
machine was refusing mail connections. AFIK, I had no firewall or other
objects blocking port 25. It has been my experience that with most
arch's and versions where sendmail is

Load balancing email?
Currently, we have two mail relays for inbound messages, and a third for POP.
The inbound messages go thru all the CPU-intensive anti-spam stuff, and then
they relay it to the POP server for pickup.
Currently, one of these is the "primary", and the other is "secondary", and
I'd like them to be considered more or less as equals, since the "primary"
system is

It is only a solution if there are subsequent attempts from the same
address. I currently have several thousand addresses blocked due to
dovecot login failures. My firewall is set to log these so I can see

postfix tightening
I am used to sendmail and am using Postfix now and am uncertain of some
features. I typically would comment out the line in sendmail.mc that
went something like 'accept unresolvable domains'
I tried using
smtpd_sender_restrictions =
reject_unverified_sender
reject_unverified_smtp
and this seems a bit too restrictive and got some bounces on legitimate
senders

ransomware etc
Hi all,
Just out of curiosity: is there anything we can do, on the samba side,
to counter the recent ransomware attacks? (or limit the damage done)
I'm thinking like: limit the number of files per second a client
(workstation) is allowed to edit, or some other smart tricks..?
It would be nice if samba could be an extra layer of defense.
Something perhaps a vfs module could help with..?

Remote reboot problem
Don't know if this might be hardware or software related, but it seems
that every time I attempt to do a remote reboot of the machine,
everything shuts down normally, and it never comes back. Just returned
from the co-lo site, and when I plugged the monitor in, it had gone to
the point of "rebooting" and hung. This is 4.3 on x-86.

How does this help Dovecot block?
A link to some documentation or example perhaps?

Is there a reason why you will not support this RFE?
