I just setup SpamAssassin and what not following this tutorial
I am using CentOS 5.3. I was half way through that and got an email that had ***SPAM*** in the subject. Haven't received any more. First of all I want to know if spam will still get delivered, and just have a modified subject. Second, I want to know how to set it up so Spam goes to a user's spam mailbox (Virtual Users). And third of all, is it possible to disable spam filtering on a user basis, preferably using MySQL tables? Is it possible for users to mark a message as spam, and all further messages sent from that address will be sent to spam folder but only for that user?
EDIT: Yes spam is getting delivered with a modified header, on the server site, how can i deliver to spam folder? how to create IMAP virtual mailboxes on request without having to send an email to them first? Using virtual users with Courier Imap
After installing postfix on my server , all emails sent by a PHP class that i built , are received to spam folder , no matter what i do .am not an expert , except in PHP , the class i built works fine everywhere else except on this server , so i think the problem might be from the server it self ?some told me wrong configuration/software on my server , others told me wrong DNS stuff . actually i don't understand the DNS stuff , and am not an expert in linux softwares and services but i cann install/configure them , so could anyone please check the DNS for problems ?
We have a vpn that is accessible to anyone. We already block port 25, 587 and 465. But I am still receiving spam reports. I believe that the users of my vpn is infected by a virus or something that sends spam. Are there any other ways that spammer send spam mails without using the smtp ports?
My guess is that they are trying to send it by accessing a webmail. Have you heard of anything like that? how to block spam?
I just saw that my network is slowed so I watches the /var/log/squid/access.log where I get this line continuously....
I thought that someone running any script so I disconnect all my LAN connection (simply removed the local lan cable) but I saw the connections is going on....so I watch the processes on proxy server but nothing suspicious....So I change my static IP and the spamming stops (I say it is spam b'coz the IP 126.96.36.199 is of yahoomail.com ) but I when I am putting my OLD ip back the connection starts again......I want to put back my old static IP b'coz I have configured it for many services. Is there any spyware on my machine or someone configured my IP?
I have an ubuntu server running postfix 2.6.5 (configured using DTC). If a user tries to send an email to more than one recipient, and one recipient address is bad, then the server returns an error and no mail is sent (even to the good addresses), rather than letting the good ones through. Error displayed by thunderbird is
"An error occurred while sending mail. The mail server responded: 5.1.1 [URL]: Recipient address rejected: User unknown in virtual mailbox table. Please check the message recipient firstname.lastname@example.org and try again." and mail.log shows ...

My company email server has been working flawlessly for the last 5+ years. Recently, one of our clients put their email server behind a firewall (an assumption on my part; details below). Ever since, email sent from within the company (192.168.xxx.xxx internal address; all computers and server is behind a NAT firewall [Netgear FVX538]) is either being sent to the client after some delay (if email is sent using Outlook) or is being deferred until the messages expire (Thunderbird, Squirrelmail, etc.). Email sent to the client from anywhere outside the company (using Thunderbird, Outlook or any other email client) is also delivered without any problems (usually after a short delay).
All other emails to the World are being sent without any problems at all (both inside and outside the company; using any email client or webmail). I did contact the client's postmaster, but the client, being a large government agency, will probably not address the problem (if it is on their side) anytime soon. I am not sure if I can do anything from my end to solve the problem. Ever since the problem with the client began, I added two statements to the postfix configuration file (smtp_pix_workaround_delay_time = 20s and smtp_pix_workaround_threshold_time = 0s); this seemed to a bit - it reduced the delay for emails sent via Outlook to a few minutes (as opposed to 30+ minutes); emails sent using Thunderbird/webmail are still being deferred.
Server details: Dual quad-core processor machine, 32 GB RAM, dual 1 gbps network, running Fedora 14 (64-bit; loosely modeled along the lines of Perfect Server (with ISPConfig2) as described on the howtoforge website). Running Postfix (v. 2.7.1), Dovecot (v. 2.0.9).
I emailed the client's postmaster suggesting they disable smtp fixup. But still, what bothers me now is that Outlook works (both within and outside the company) while Thunderbird, webmail, etc. (used by ~90% of the users) do not. In addition, all email clients from outside the company can send email (authenticated via the company server) to the client without any problems. Is there anything I can do on my end to make non-Outlook clients work within the company (webmail is hosted on the company server; so, it would have an internal address as well)?
We have MS Exchange email server with postfix/amavis on FreeBSD as proxy for anti-spam and anti-virus. We use our own developed CRM and trying to implement such functionality that when CRM manager send email to CRM client or vice versa through email client like Outlook (no plugins for CRM) this message would be shown in CRM. There is already a solution to parse emails from specific emailbox and show it in CRM.
What I need is to create postfix email filter to check if sender email is in file CRM_managers_emails and recipient email is in file CRM_clients_emails then forward that email to [URL] Filter should check both incoming and outgoing messages. I will auto generate CRM_managers_emails and CRM_clients_email files containing all such emails taken from CRM database. I know i should use something like Postfix After-Queue Content Filter but most of examples are for blocking emails.
I'm setting up email gateway using Postfix, Amavisd-new, ClamAV and SpamAssassin on Opensuse 11.1. Everything seems okie, but I can't have messages with added spam headers, such as:
X-Spam-Flag: NO X-Spam-Score: 0.233 X-Spam-Level: X-Spam-Status: No, score=0.233 tagged_above=-10 required=6.6 tests=[ALL_TRUSTED=-1.8, AWL=0.536, BAYES_50=0.001,]
When I try to debug amavis, I can see that SPAM-TAG, <firstname.lastname@example.org> -> <email@example.com>, No, score=5.406 tagged_above=-999 required=6.2 tests=[LOCAL_DRUG=4, NO_DNS_FOR_FROM=1.407, NO_RELAYS=-0.001] but they don't add to email messages. I've configured amavisd-new with $sa_tag_level_deflt = -999 to add spam headers at all but not successful.
We use procmail to reformat and filter email messages sent from many lead capture websites where the clients enter their reply email address manually.When we receive the message at our application we send a welcome email, and receive back the Undeliverable Email message where the clients entries are invalid, but I would like to be able to kill messages with undeliverable email addresses on our mail server before they are delivered to our application.I have found discussions on filtering masqueraded addresses, but since the IP of the sending system is not related to the entered client's email address, this does not appear to help. I would think that it should be able to query the email server to identify if the address is valid.
How to configure my home linux server, as an email server, and be able to send email to hotmail, please?. I have done this before, but I never managed to do it so hotmail accept emails coming from my linux server.
So I have Postfix working great and I've always used webmail if I needed to send email from PC's outside of $mynetworks. So fast forward to today where I got my 1st Android powered mobile phone and I can configure the Android mail client to send/receive IMAP email but my question is do I need to become an open relay to allow my random wireless providers dynamic range of IP's to send mail via Postfix? Seems extremely vulnerable and scary to think I would have to allow my providers IP range to relay mail via my MTA. I started reading a bit and I think I need SASL authentication and since both Postfix 2.8.1 & Dovecot 2.0.11 are both configured / using TLS, is there anything else I would need or you recommend for sending email from my Android powered mobile?
I have postfix sort of working correctly. postfix can send email to the internet but it doesn't want to send email to my local exchange server. What I need is for postfix to send emails directed to @xyz.com to my exchange server instead of itself.
My setup mail.xyz.com - exchange 2003 server www.xyz.com - centos 5.3 server with postfix
www.xyz.com can send emails to my hotmail.com account so that part works correctly. www.xyz.com can't send email to firstname.lastname@example.org. postfix seems to be delivering the email to itself and not the exchange server.
How can I tell postfix to send the @xyz.com emails to my exchange server?
Here is a sample of my /var/log/maillog Jul 22 15:43:43 list postfix/smtpd: D63168604A3: client=localhost.localdomain[127.0.0.1] Jul 22 15:43:53 list postfix/cleanup: D63168604A3: message-id=<20090722204343.D63168604A3@www.xyz.com>
i am using centos 5.4, running squid for proxy, i want to block email sending and receiving of proxy users to secure my data. how is it possible that the proxy user can only brows websites but he can not receive or open and send or save as draft to mail box.
Our mailing systems was working in web mail and we had a tool wherein if we apply leave mails where sent to web mail. Now we have moved to exchange server and we want the mails to be sent to exchange server. The Leave Management systems is developed in PHP with Mysql the platform used is linux.
We have a spam in our network and we installed antivirus in all our systems and cleaned the virus from all pc's after that i had removed my ip from the database of blocked ip's but still my ip is blocked for sending spam i don't know from which pc the spam is going on the internet.
so i have a question that my proxy server is redhat linux and as a newbie i don't know the command's to find out which pc is creating large bandwidth to the internet. If you tell the command how to see which pc is sending spam then i will discard that pc. Also i want a strong firewall to stop spam activities.
The scenario: We have an external server that runs HTTP/DB servers for out shop system. Then, there's our local, in-house infrastructure that runs a.. yeah... Exchange 2010. The shop system on the external server needs to send mails to customers (order confirmations, invoices, etc.). seing as sending them directly through the local MTA (Postfix) would cause mail delivery problems because of reverse DNS issues, i've set the Postfix MTA to act as a satellite to our in-house Exchange Server, so the Exchange sends the mail instead, giving recipient mail servers a valid reverse DNS lookup.
Now, mails sent by the (proprietary, uneditable) shop system are relayed correctly and sent to the target e-mail address. My problem is: Mails not sent by the shop system, but by our own PHP scripts which run on that same external servers, are NOT relayed properly. So the Exchange is fine with the mails sent by the shop system, but not the mails sent by our scripts. This is what i get in the mail.log: The successfully relayed mail sent by the shop system:
I am working happily with Fedora 8, evolution chatting happily to exchange 2003, calendar sync the works...impressed. This continued through Fedora 9 (though a little bumpy as all odd numbered Fedora releases are). On to Fedora 10, yes works a treat out of the box (DVD). A couple of updates to evolution later, through yumex (fedora updates), and evolution has stopped sending email to the exchange server. It's also touch and go whether I can read email using OWA.
On pressing 'Send/Receive' evolution pops the error, Error while performing operation. Exchange transport can only be used with Exchange mail source. How could I back out these evolution updates?
system is RedHat v4. I removed root: admin-name@domain from /etc/aliases then ran /usr/bin/newaliases.
The admin does not get the emails but now the email generated by the cronjobs is being sent to my-name@domain outlook email from "email@example.com". No other changes were made. Where should I start looking for the definition of sent crontab email to my-name@domain?
I'm looking for a way to redirect e-mail with postfix based on sender AND recipient. What I want: Let's say I have 3 users:
and an external address, let`s call it [URL] sends e-mails every day to andy, mark and john Now, MARK and JOHN, need the e-mail sent by [URL], but TOM doesn't need it. Is there a way to redirect ONLY the e-mail sent to TOM from [URL], to some other address, let`s say [URL] without affecting the e-mail received by MARK and JOHN? Unfortunately using SENDER ACCESS redirects ALL e-mail from [URL]

Did anyone heard about or can suggest mabe a postfix serverside solution in order to insert a counter number into the subject line before the message is sent? I mean something similar with helpdesk tickets, because I would like to create the possibility for the senders, to make further refference about a speciffic message using it's counter number provided by postfix server.
The mail server keeps getting locked up with tens of thousands of spam emails.So, i followed some instructions similar to this : [URL]I can clear the queue spams, easy, but after an hour or so the server is dead again.. not receiving emails and not sending out emails.
