Dear Friends Greetings, i wish to setup SPF look up f0r Postfix on CentOS 6.2. I could not find any document on the net describing the procedure. is anyone have documentation i can follow to setup the SPF please? Thanks / Regards Prabhpal S. Mavi

Dear Friends, i have setup SPF alright, postfix is performing check as well (results below), but even if there is no SPF record exist for a domain, message is still accepted. how can i set the reject action, if no SPF available. May 3 16:11:14 titan postfix/policy-spf[5353]: : SPF none (No applicable sender policy available): Envelope-from: somedomain.com Prabh S. Mavi

I am inquiring about how to setup a proper SPF record. I know there are SPF wizards/generators available but each seem to have a different "opinion" of what should be included and what should not be included. Let me give you a scenario of my setup, and hopefully someone can help me out. My domain is: test.com My mailserver hostname is: mail.host.com which also has a MATCHING PTR

Say someone has setup spf for his domain and sends an email to a user that has in roundcube enabled the sieve forward. If the message is forwarded without altering the message headers, this could result in a message being blocked or not relayed, because sending hosts ip, is not in the spf of the from: domain. Possible solutions are: - add option if enabled, it replaces the From: with that

Hello Dovecot gurus, I've set up SPF checking on my postfix gateway and have confirmed that messages from domains set with hard fails that don't come from a good sender are rejected outright. Messages from domains set with a softfail that come from bad sources are tagged in the message header with "Softfail (domain owner discourages use of this host)", but end up in the

Since I've upgraded to dovecot 2.0.13 + Pigeonhole 0.2.3 (Gentoo package) I've received a few complains of users about rejected messages. Investigating the problem, I've seen that when the external sender server publishes SPF information, when some message is sent from there to one of my users that has a Sieve redirect action active to another external system (that does SPF

Does anyone have any experience with adding SPF support to sendmail?? Thank you, -ed-

I was wondering if there was any way to set the ''Return-Path'' of an email when using ActionMailer. Without the ability to set the ''Return-Path'' of an email, it is impossible to avoid being labeled as ''spam'' by many SMTP gateways if trying to send mail on another''s behalf. SPF doesn''t care about the

I know this is a bit off topic from CentOS itself, but are there any DNS experts that would be able to e-mail me on the side and assist with some questions I have regarding TXT/SPF records? I want to ensure my mail doesn't bounce.

Hi, it seems not to be possible to add more than one host at once to a zone. So shorewall add br0:eth0:192.168.2.10,eth0:192.168.2.11 work fails, since "br0:eth0:192.168.2.10,eth0" is interpreted as one interface. --snip -- iptables v1.2.9: interface name `eth0:192.168.2.10,eth0'' must be shorter than IFNAMSIZ (15) Try `iptables -h'' or ''iptables

Hi, as per the shorewall MultiISP documentation ( http://www1.shorewall.net/MultiISP.html ), it says "Use of this feature requires that your kernel and iptables include CONNMARK target and connmark match support (Warning: Standard Debian™ and Ubuntu™ kernels are lacking that support!)." it means MultiISP wont work properly if i am using Ubuntu server. if yes whats the

For those of you running SuSE 9.1, I do not recommend upgrading to 9.2 at this time. Refer to http://shorewall.net/myfiles.htm for information on my configuration: a) On Ursa: 1) After the upgrade, both of the NICs were recognized as "configured" in YAST yet neither of them would start; ifup claimed that no configuration could be found for either interface. Only got them running

I think it would be nice to be able to rate limit an action, too.. suppose I have an action named Accept_good_source : ACCEPT - - tcp - 1024:65535 ACCEPT - - udp - 1024:65535 and that i want to use it in an action called AllowCVS, i can''t limit the cvs usage, but only the general use of Accept_good_source... same goes for userset... as each rule will give one iptables command, I

Group, I am reading about tc (traffic control) and willing to get my feet wet. As requirement, there should be HTB compiled in the kernel. I grabbed a Mandrake 8.2 distro, and didn''t installed the kernel source. Anyone knows if the HTB is compiled in Mandrake 8.2, or point a way to find that out? I tried to read the /usr/src/kernel.xxxxx/.config file, but it doesn''t exists.

Hi I am looking at converting a Linux terminal server box to iptables using Shorewall 2.0. (At the moment it uses ipchains). The server currently has scripts which are called as each user logs in which run a series of "ipchains" commands to set the access rights for that user (and again to cancel them when the user logs out). My plan is to replace these scripts with ones that call

There's no ambiguity here, if you send a message, you are the sender. The envelope from should be yours.

What''s the directors'' take on ading DKIM or SPF functionality into ActionMailer. Is that a function that is better addressed via a plugin, or would an extension or a monkeypatch of this class be an appropriate avenue of pursuit?
