Hi list,
I have noted over the last week or so my DNS servers are dumping lots of

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

Hi everybody,
I am trying to work with quota. I use postfix and dovecot with a sql

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:

Thanks for the help in advance.

Postfix restrictions
Hi,
I'm currently fine-tuning my mail server (Postfix and Dovecot on CentOS 7).
SPF, DKIM and DMARC work fine, now I'd like to limit the spam tsunami.
Besides the official Postfix documentation, I've read a few articles about
Postfix spam restrictions, namely these :

Postfix smtp_recipient_restrictions causing mail to fail
Hi All,
I'm currently playing with smtp_recipient restrictions to try and knock
some of this spam on it's head. On my old debian server, I was using
this and successfully filtering out at least 90% if not more of all spam
emails which was great. I didn't even need spamassassin.
However, trying to do the same thing on my new CentOS based server isn't
working. With the

SASL attacks and SPAM
I wanted to pass this along. I'm sure it may be nothing new to most of you,
but it has greatly reduced sasl attacks and spam.
I found most of it here:
https://scottlinux.com/2011/05/26/prevent-postfix-brute-force/
I added the fail2ban rule and modified my postfix main.cf as follows:

Trying to get DSpam+Dovecot working with Postfix and local/virtual domains
Hi,
I'm hoping that someone might be able to help, as I've been going in
circles with trying to get the right configuration done here. I'm also
not sure whether this is more of a Dovecot or DSpam question, so I'm
posting the same to both mailing lists.
My goal is to have a mail setup that is as follows:
[Incoming email] --> [Postfix] --> [Amavis] --> [DSpam] -->
