I read somewhere that I need the trusted-users file with the valid users id, which I had. UserA is inside trusted-users.
Scenario:
Sender send email to userA.
UserA had a autoreply set, but was somehow set the sender to UserB instead of UserA (See below log)
User A - .forward

I am using sendmail v8.14.3 (slackware 12.2, kernel 2.6.27.7-smp)
After configuring sendmail in Linux I am able to send a mail once only. After that whenever I try to send a mail like this:
telnet localhost.url 25
EHLO localhost.url
MAIL To: susan@url
RCPT To: harry@localhost.url
MAIL DATA
after that whenever I press enter it gives me an error :
Sender Already Specified 503.5.2
Can anyone tell me why it gives this error and how can I remove this error by doing changes in which file and how?
I have a mail script that has been running on my website for several years. One problem I had with the script was when a bad address was put in, the mail was rejected to the server rather than to the sender. I have now recently added a fifth parameter to the mail script using the -f sendmail option to set the return path.
PHP Code:
$mailsend=mail("$email","$subject","$emess","$ehead","-f$adminEmail");
The PHP manual says this:
Quote:
The user that the webserver runs as should be added as a trusted user to the sendmail configuration to prevent a 'X-Warning' header from being added to the message when the envelope sender (-f) is set using this method. For sendmail users, this file is /etc/mail/trusted-users. I do have the 'X-Warning' header on e-mails sent with this script and have asked my server administrator for some help in adding "the user that the Web server runs as" as a trusted user.
We're using mutt to send out a daily email through cron. The only problem is that half the people aren't getting it, because its getting rejected as coming from an invalid address. Right now its sending out as username@localhost.localdomain.
How can I change this? I found the sendmail.cf, which I believe previous people have been editing directly, which from what I read isn't the best way to configure sendmail.
I need to override envelope sender address from UserID@Servername.Domain to UserID@domain when sending mails from my Linux server.
1. currently if send a mail, it arrives as myuserid@linuxserver.domain.com instead of myuserid@domain.com.
2. Also, the mail is not being sent to other domains outside our comp network.
i have installed redhat 5.3 and install sendmail on it.it is working perfectly fine.my question is|:
(1) can i restrict the sender and receivers email in sendmail?eg. i want to do that i want to allow only particular email addresses to send and receive and all other will be discarded
(2) i made aliases for all user but it only receives received mail copy i want both sent and receive mail copy in aliases.
I got one last stop until I've fully configured my Sendmail server. I want the server to verify which address the sender is using when sending mail. Even though authenticated via SMTP AUTH or mailing from an IP listed as RELAY in access.db, the user should not be able to use whichever address he likes.
Ideally, I would like Sendmail to use a file that looks something like this: Username sername@Server.org
where, if logged in with Username, the only accepted sender address is Username@Server.org. As of now, Sendmail just verifies that the sender domain exists and then relays which I don't like. This also applies to a lot of other servers as well... for example in the cases where ISPs have blocked outgoing port 25 and let all their users use their SMTP server. I assume, if they don't use SMTP AUTH which is not the case where I am, that they have their entire IP range listed as RELAY and therefore, using my ISPs SMTP when in their net, I can send mail as whomever I like as long as the sender domain exists.
I've had a look at filters but haven't found any suitable and I assume that this might be realised through a Ruleset or something. What do you think? Have I missed something making this a really stupid suggestion or am I on to something? It would make my day
I'm trying to configure our mail server to block email from a specific sender reaching a specific recipient. In other words, if one of our employees is getting harassed by a 'stalker', how would one go about blocking, at the MTA (Sendmail) level, a specific sender email address from reaching a particular users inbox? We do not want to capture the email - simply block it before it consumes server resources.The Sendmail server (MTA) is a front end to our Exchange server so no user accounts exist on the Linux server. We simply use it as a SPAM and Virus scanner then forward clean email to the Exchange server.

I recently modified sendmail.cf to use a third party SMTP server to send emails. It works great. But when I run sendmail from the command line, I have to specify the -C flag and force feed it the location of my sendmail.cf, or else it doesn't work.
So in other words, the following works great:
However, if I don't specify the -C flag, sendmail doesn't consider what's in the sendmail.cf and barfs:
I don't run sendmail as a daemon. I'm only using it to send emails. I know my modifications of sendmail.cf are correct because it works perfectly when I use the -C flag. I searched my disk to see if I could find another sendmail.cf on the machine and only the one in /etc/mail came up.
Why sendmail is not reading my sendmail.cf?
I'm running Sendmail version 8.14.2 on Fedora Core 8.

I want a mail server that can relay mails to the internet using GMail and fetch the mails of different accounts into the mail server and distribute them to their respective users. I am using Postfix, Fetchmail and Dovecot. I have a PC with 3 users.I use the PC having Ubuntu 9.04 and share the internet. We all send mail and retrieve mail. We do use Evolution and Mutt sometimes. We want to send our mails with our email_ids without even logging in.
Hostname
mail.myhomepc.com
Domain
myhomepc.com
[code]....
I have created my custom certificate using SSL. I've created the Postfix's main.cf file following a tutorial on the net. Currently mails are going fine, but with our local email_ids. I want Postfix to rewrite our local email_ids with the equivalent email_id on the net.
I have observed in a process's log file that it is receiving a number of connections from other processes running on the same box.
For example, I see lines of the following:
While I can use "netstat -tlp | egrep '5870|5871'" to see the PID of the listening process. How is it can I find out what PIDs are sending from 23870 and 23548?
I can not find a way of removing original email addresses from a email I wish to forward so I can maintain the privacy of the original sender.

I need to have a postfix server to rewrite the sender's address. For example, if the sender is: [URL], then the recipient would receive all emails from [URL] as [URL]. I tried using the generic file and created a table out of it, but this did not work:

View 3 Replies View RelatedI am trying unsuccessfully to have a more permanent fix so I can receive emails from an invalid domain. The message is 'Sender address rejected: Domain not found' in the postfix mail logs. Fair enough, there may be an A record or MX record problem there, but there is nothing I can do about this with the Sender at present. Mail *will* come through from the invalid domain if I delete
Code:
reject_unknown_sender_domain
from the list at: smtpd_recipient_restrictions in /etc/postfix/main.cf (see coded area below for full list). I have added the Domain in question as an 'OK', both by name and by IP address, to: /etc/postfix/recipient_access, then used postmap to successfully create the database which appears as: recipient_access.db
ie recipient_access (not recipient_access.db) has contents: invalid-domain-name.com OK ; the space betw is a tab space 123.456.789.012OK ; the space betw is a tab space I suspect the failure is something to do with postmap and the recipient_access.db database file created by postmap, but just cannot work this out. Running: postconf -d indicates that the hash format is the default database format
As indicated below,
Code:
check_recipient_access hash:/etc/postfix/recipient_access is listed up front in smtpd_recipient_restrictions Postfix was restarted on all occassions Everything above was done as root and permissions on the .db files are the same as other files in /etc/postfix
From /etc/postfix/main.cf:
Code:
smtpd_sasl_auth_enable=yes
smtpd_helo_required = yes
disable_vrfy_command = yes

block incoming email within either postfix or spamassassin when the sender equals the recipient. The manner in which our mail infrastructure is set up would preclude this from happening. Granted, we do have outside vendors that spoof our domain so we have to allow emails in with our domain as the sender/from. The vendors do not, however, utilize the same sender/recipient when sending emails.
View 1 Replies View RelatedI have installed postfix and dovecot on my server and thought postfix will not only take SMTP connection from my e-mail client like Outlook, but also handles "mailx" commands from the server. However, it looks like sendmail is still responsible for sending mails from "mailx". I tested this by turning it on/off using "service sendmail stop" and "service sendmail start". Mails sent using "mailx" will only be sent when sendmail is up. When I did "yum info sendmail", it lists sendmail as an installed package. Is is safe to remove sendmail by running "yum erase sendmail", and let postfix handles "mailx" also?

In fact I'd even say it works too well: in squirrelmail, I can configure any sender address and my server will accept it. Message will be sent, wether the sender's address is [URL] or [URL]. Is there any way of limiting it in such way that only [URL] is accepted as sender's address?

View 6 Replies View RelatedI'm trying to extract the sender id from a fairly large number of files and am having trouble assigning variables from a file. Here is what I have so far, (which is fairly kludgy I know, but it's been some years since I've done any scripting or programming, and I find that I have lost the knack to a large degree).
[Code]...
Request your help in writing a shell script for the following requirement:
1) scan each incoming mail with conditions on sender name and subject
2) scan the mail body for set of characters and email them.
general usage is as follows: I get a mail as follows from: [URL]... subject : Urgent, reply body : name : xyz contact : 12345 the script should mail the following as subject line: n:xyz c:12345 I know procmail is a good option for this, but I'm compelled to use shell script
Under folder /home/user there are two files : .autoreply (where is the message text) and .procmailrc where is the procmail for autoreply. So .procmailrc looks like this :
[code]...
And it works, returning to the sender the text from .autoreply file. BUT it send this text from the mail account which looks like this: name-from-/etc/passwd-file@server-hostname instead (in my case) [URL]... Under webmail (squirrelmail) the reply address is set as it should be. I looked up a bunch of Internet pages, to no avail. Also masquerade is not a option because my production system has two mail domains.
