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 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.
Our system uses email to send fairly time-sensitive status messages between programs running on various servers on a WAN. Each email message is sent to two addresses (different servers). The problem occurs when one of the destination mail servers is off the network. I think because it's trying to send one email to two addresses, sendmail attempts delivery to the first address, then to the second address (i.e., serially). When this happens, it hangs for two connect timeout (CONNECT_TO) periods trying to connect to the offline destination, then after the timeout, it then delivers to the other destination. I'm trying to figure out how to work around that connection delay so it doesn't delay delivery to the other destination.
I'm working with the network guys to enable the right ICMP messages that signal when a network is unavailable, but I would also like to try having sendmail split the emails into two envelopes, then use parallel, independent connections for delivery.
After days of reading through the docs (O'Rielly Sendmail book + sendmail docs) I think one way to do this is to use multiple mail queues, but I can't decipher exactly how to do that from the docs.
There might be other, more elegant ways to do the same thing, but again, trying to decipher the docs has my head swimming. (This is my first experience with sendmail.)
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 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
Is it possible to using 2 envelope options on fetchmail? Here is fetchmailrc configuration :
envelope "Envelope-To"
envelope "X-Apparently-To"
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.

UserA had a autoreply set, but was somehow set the sender to UserB instead of UserA (See below log)

I am using sendmail v8.14.3 (slackware 12.2, kernel 2.6.27.7-smp)
I recently tried to upgrade my Slackware server's sendmail software from 8.14.3 to 8.14.4 and ran into a problem. In a nutshell all outbound non local mail is routed through a smart host requiring authentication. As a result I use a modified version of the "sendmail-slackware-tls-sasl-clamav.mc" to build the sendmail.cf. However, when I tried to run sendmail 8.14.4 with my newly created sendmail.cf I was greeted with the following.
Warning: Option: AuthMechanisms requires SASL support (-DSASL)
Warning: Option: AuthOptions requires SASL support (-DSASL)
Warning: Option: CACertPath requires TLS support

Apparently SSLv2 is now considered weak and the directive is a good idea, but at present this directive is not supported by the sendmail in this package.
what is suid or nosuid and would it override nfs server? I really don't know what this all means. whats the difference?
View 1 Replies View RelatedUp front: the per browser (or per process, if you will) part is the important part here. I'm well aware of the /etc/hosts(and its Windows counterpart), but would like to avoid this system-global method.
What tools exist to override the IP for a given (i.e. configurable) name per browser? For Firefox there are "Modify Headers" and "Tamper Data". Both of them do not appear to be suitable for my case, because the DNS lookup is done before that. So I can only modify the HTTP headers (e.g. the Host header), but not influence the IP to which it gets sent. But manipulating to what IP it gets sent is exactly what I want to do.

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:

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
I want to know how can I use sender an receiver of the email in name of file for storing mail in procmailrc. I made one but it does not work.
Quote:
SUBJECT=`formail -xSubject:` # regular field
FROM=`formail -rt -xTo:` # special case
:0 b
* ^FROM.*
| sed -e '/^To: +?[0-9]*$/,/report/!d' > ${FROM}${SUBJECT}--`mktemp 20`date +%y-%m-%d-%S--`XXXXXX`
it works when I use :

I 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?

I am using FC15.I need a kernel with a different configuration - with the "Preemptible Kernel (Low-Latency Desktop)" option in the Processor Type and features menu. I need this to support my firewire audio device. I would like to build a new kernel RPM from the SRPM so that i can keep a clean system with RPMs for all files, and I don't really want to manually override the kernel bypassing RPM.I am following **exactly** the process described there - I install the SRPM, unpack the source, then use the starting sample config files in the BUILD folder to create a new customised .config file with the new option, then copy this back to the SOURCE folder.
This works perfectly if I make a standard kernel. But I cannot get the process to work if I change the config file. Every time I compile I end up with exactly the standard kernel -- a vanilla i686 kernel, without my custom config.I believe the problem is that when I run rpmbuild to compile the kernel, this process overwrites my config option. I found that there is a script (merge.pl) which creates new config files dyanmically for all kernel options based on fragments in the SOURCE folder. It looks like the script never uses the config file that I am putting into the SOURCE folder.The wiki page suggests using this command to copy my custom config file cp .config ~/rpmbuild/SOURCES/config-`uname -m`
