Hi all.
I have an postfix installation configured to use my ISP's server as
relayhost.
I don't want to put too much load on it (and get blacklisted) so I'd like
to limit the number of messages sent per minute.
I found previous posts on how to do that per destination domain - but how
about the relay

Hi all.
Today, while sending an email, I monitored postfix's log. The message was
going thru postfix and then relayed to the recipient's MX:
Jun 8 13:03:21 dsrv postfix/smtpd[13477]: AADDD17B812:
client=whatever[xx.xx.xx.xx], sasl_method=LOGIN,

Hi all.
Our internal postfix server relays all outbound mail thru an external host.
How can I set it to use a different relay server when the email comes from
a specified domain? Eg. j...@domain1.com -> xxx.xxx.xxx.xxx (default),
m...@domain2.com -> yyy.yyy.yyy.yyy
Thanks.

Hi all.
I have a Postfix virtual users setup based on mysql tables. Messages are
stored in Maildir format.
I am aware that creating a virtual alias @domain1.com -> u...@domain2.com
will make Postfix accept emails for any username and deliver them to
u...@domain2.com.
Is it possible to do the same

Hi all,
I have a Postfix virtual users setup based on mysql tables. Messages are
stored in Maildir format. Maildirs are owned by "vmail:vmail" .
I want another user to be able to read those Maildir files so I added him
to the "vmail" group.
Unfortunately Postfix seems to create the directory struc
Hi all.
Somehow spammers got hold of a couple addresses in my sender_bcc_maps and
are sending mail directly to those. How can I restrict the source of
messages to those addresses to localhost only?
Thanks,

Hi all.
Is it possible to store a CIDR access table on a mysql database? It would
be very useful so I could have a centralized list to serve all MXs'
instead of rsync'ing files each time.

Hi all.
We have a local postfix server that relays to another postfix server via
VPN and I would like to remove the "Received:" headers so that only the
last one is included in the email message.
How do I proceed to do that? Do I need to set up altermime?
Thanks

Hi all.
Every day I have a bunch of messages stuck in the active queue because of
address typos made by the sender. Some of them I just let exprire and go
back to the user, but others could be so easily fixed (eg "hotmal.com"
instead of "hotmail.com") that I would like to do that myself.
Is there a
Hi all.
Is it possible to have a transport map with a regular expression? What I
want is to use an external relay server for all the emails to be delivered
on Yahoo domains (eg, yahoo.com, yahoo.co.uk, yahoo.es, ecc).
If it is possible, how can I implement this?
Thanks.

Hi all.
I currently have this smtpd_sender_restrictions setup on a mail server
hosting several domains:
smtpd_sender_restrictions =
permit_mynetworks,
reject_non_fqdn_sender,
check_sender_access hash:/usr/local/etc/postfix/sender_checks,
check_sender_access hash:/usr/local/
Hi all.
I'm looking to filter emails that have a specific return-path address.
As far as I understand, the rule's going to be in header_checks..but can I
REJECT or only DISCARD the message?
Also, what should the regex look like? I tried a quick fix yesterday but
it doesn't seem to be working:
#/^R

Ok, but will it work even though From:<> != Return-Path:<> ?

Hi guys.
I'm looking into implementing a check_recipient_access as a table inside a
MySQL database.
It's basically a list of users that have been banned from the system and
for whom I don't want a simple 550 user unknown bounce.
Currently the list is a flat file hash map:
u...@domain.com REJECT Th

Hi guys.
My mailserver uses a relayhost which basically only signs messages with
DKIM and delivers them.
I would like to add a custom header, something like "X-Abuse: if spam/uce

How should I go about, without postfix adding the header twice (before and
