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.

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

seeding dev/random in 5.5
I was doing some regression testing in 5.5: Specifically testing booting
up a 'virgin' hard disk from a clean install.
I was testing what happened if the 300 second timeout happened vs
hitting <return> for 'fast+insecure' startup and punching in a bunch of
random garbage.
I found that for some reason, on a 2.4Ghz Celeron, the 'sysctl -a' and

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

Applying a DNS RBL to deny authentication?

Status of SPARC64 port?
I was looking at the Sparc 64 4.7 or 4.8 port, wondering if its in any state
to put on my Solaris v100.
Just need the basics, eide, network, kbm,mouse, graphics (x).
A bonus would be support for the lom (light out management) features and the
flash card.
Reason for change is I HOPE that the math (ssl) performance is better on

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

[Bridge] Any way of knowing a packet's been defragmented
Hello,
Due to a recent change in the bridge code, we now need a way of knowing if
a packet has been defragmented. The bridge code now checks on the packet
size and drops packets that are too big for the output port. Defragmented
packets will get refragmented later, so they shouldn't be dropped.
I've been reading the defragmentation code and can't find an easy way of
knowing if a

be nice igf gam would accept an na.action argument, but that not the
main point.
I want to have a smooth term for time over a year, the same pattern
repeating in succesive years. It would be natural then to impose
the condition s(0)=s(12). Is this possible within mgcv?
