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

postfix and spam, I am impressed
I have had the same email address since 1997 (when microsoft stole
bob.com from me thanks to network solutions...)
In the early days I of course was free with my email and used it everwhere.
Fast forward to 2012, some 15 years later.
woof..the amount of spam sent to me has always just kept getting worse
and worse.
On my centos 5 server I just used sendmail with spamassassin and it

Postfix and choice of RBL
Hi,
I'm managing several mail servers running CentOS 7, Postfix and Dovecot.
SpamAssassin is filtering mail nicely, but I'm considering using RBL
(blacklists) to take some load off the servers.
General question to those of you who use RBL. Which lists do you
recommend using?
Cheers,
Niki

In my "reject_rbl_client" lines, I've been using:
- hil.habeas.com
- sbl-xml.spamhaus.org
- bl.spamcop.net
And in my reject_rhsbl_sender line, I have:
- ds.rfc-ignorant.org
Additionally, I've got Postgrey enabled, which does a really good job of
weeding out the spambot desktops and such.

Instead of using reject_rbl_client the better choice is to use
postscreen within Postfix. That enables the admi...

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

blackmail attempt? Stable mailing list block?
I got some weird mail back, claiming that my e-mail was blocked, w/o
indicating what server was blocked, after the mail appeared in the
mailing list. Is this some BS shakedown? I use postfix on a DSL line
forwarding to earthlink, this is hardly something that should be rare
in the BSD world... the mail appeared to come from a web mail server
and the first link has the following lovely text:
