Fedora :: Postfix Or Sendmail Virtuser?
Aug 6, 2009
browser just crashed trying to upload the config file at the end, so I fi miss something, sorry.I have been trying over the past few days to get either postfix or sendmail to properly forward my emails. I have made an entry in virtusers (for both postfix and sendmail) as:[URL]..I know that they these files are mapped correctly because I did an entry of:[URL].. that worked, it sent it to root's mailbox. I got this to work in both sendmail of postfix. What the problem is that when I point it to an external domain (ex. name@gmail.com), it fails, and the email gets lost somewhere on my server (I have yet to fine where they are going). The other thing I noticed is when I send an email from my server (via php) and send it to test (or whatever)@example.com the catchall works, and sends the email to my gmail address. Is this virtuser only applicable for outgoing email? Or is something else wrong?

I have isntalled a server with Centos 5.2 OS, now I would like to switch from the default sendmail to postfix doing a yum install postfix I've noticed there is already available an rpm version for the OS but I would like to compile my own 2.5 version, I've noticed compiling from source does not allow me to use the mail switcher to tell to the system I'm gonna use Postfix instead of Sendmail as the default MTA while this is possible when I use the "official" rpm version of the package. Now my question is this, would this be a problem? There is some specific procedure/best practice I should follow? Or once compiled and configured Postfix I can safely disable/uninstall sendmail?

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 on Scientific Linux. While trying to remove sendmail, YUM asked to remove depended packages:
alpine
fetchmail
mdadm
mutt
redhat-lsb
sendmail-cf
Should I really remove them and sendmail? If trying to install potfix, YUM does not say that sendmail is incompatible and does not ask to remove it.

I have a lightweight admin background, but good enough to set up most servers. I have switched from sendmail to postfix for the first time, but I keep going around in circles on the following. In sendmail, I used to maintain a table (mailertable) where I would redirect email like this
[Code]....
I happily mapped any incoming email address of any valid hosted domain either to go out to it's final destination via smtp, or if the person has a local mailbox, it delivered locally. Any errors could be forced, and a catch-all for the domain could be directed also.
I've struggled with virtual hosts and transport and a combination of the two to come up with the same result for postfix. I have this feeling I'm missing something really simple, or I am not 'getting it' when I'm doing something postfixy and I still have sendmaily expectations. right path so I will at least know I'm pointing in the right direction and working with the right files to achieve my aims? Postfix is so amazingly powerful and flexible, I'm having trouble figuring this bit out.
I have this feeling I just need a calm hand on my shoulder, a friendly smile and a hand pointing me the right way..

I've tried to configure the mail service in RHEL6 but seems both sendmail and postfix can't use local user located in /etc/passwd.
Like, user Tommy and Jake they got User Unknow from maillog
Tommy:x:506:507::/home/Tommy:/bin/bash
Jake:x:507:508::/home/Jake:/bin/bash
But IF I use users' home folder not located in /home then it can go throught.mailuser2:x:513:514::/rhome/mailuser/mailuser2:/bin/bash mailuser3:x:514:515::/rhome/mailuser/mailuser3:/bin/bash

I'm hoping someone here can help, as I've been beating my head on the wall for a week now with little advancement. I've found a number of tutorials on setting this up, however none of them have gotten me 100% of the way there. Here's my situation: home-based Fedora server (Core 8), running sendmail 8.14.2-1. Connecting to hosting company's smtp server over port 587, to bypass Verizon's blocking of port 25.
My /etc/mail/sendmail.mc file looks like this (comment lines removed):Quote:
divert(-1)dnl
define(`SMART_HOST', `smtp2.datarealm.com')dnl
define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 PLAIN')dnl
FEATURE(`authinfo',`hash -o /etc/mail/auth/client-info.db')dnl
define(`RELAY_MAILER', `esmtp')dnl

i currently installed centos 5.3 with postfix. My old server is centos 4.5 final / new 5.3 final. Old server has sendmail / new has postfix. how can i transfer all the mail and settings from the old to the new? also, the old mail server is mail.xxx.xxx and for testing purposes i named the new mail server mail2.xxx.xxx.
when i an ready to put it into production, the new server will need to be mail.xxx.xxx and the old removed from the system. How do i go about changing the name and making sure everything comes out correct?

I cannot get either sendmail or postfix to send a 220 response, nor respond with details. See below for sample telnet output. Details: I have a server that requires email, but only for light use. I'm definitely not an expert, but I have set up a sendmail configuration on a previous server. I tried to configure sendmail first and then postfix later, when I couldn't get sendmail working. I'm not sure exactly what the problem is, but I have a feeling the following might yield some important information. Note: this is the result for Postfix, but virtually the same thing happened with sendmail, too. That is, initially the telnet connection would close immediately. Afterwords, I could connect a second time but then it never responded with a 220 banner nor any 250's.

I am using webmin for my daily tasks. I have fedora 13, whenever I click on ''Sendmail M4 Configuration'' or Outgoing Addresses (generics)'' I get the following error message
Quote:
The Sendmail M4 configuration base directory /usr/share/sendmail-cf was not found on your system, or is not the correct directory. Maybe it has not been installed (common for packaged installs of Sendmail), or the module config is incorrect. I read documentation at sendmail.org, it seems that structure of directories for send mail has been changed in version sendmail-8.1.4 shipped with FC13. In webmin config module we have
Quote:
Sendmail M4 base directory = /usr/share/sendmail-cf
which is not there. I did a locate / sendmail-cf on the command line, it finds nothing

I have been trying to set up ssmtp so I can send email using Gmail's ssmtp servers. However, when I try to send mail (using mailx), I get the following message:
Code:

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.

so i set out to change the default smtp port the server uses because my ISP blocks port 25 and i need the email to work in outlook. this morning i could receive email, but not send it. so i did some research and thought that i needed to edit the master.cf file in /etc/postfix/ by commenting out this line: smtp inet n - n - - smtpd -oand replace it with587 inet n - n - - smtpd (587 being the port i want to use)somewhere along the lines postfix server stopped running and now i cannot get it to start.if i try using SSH it crashes immediately and if i restart it in simple control panel nothing happens

I recently moved over user from an old box running postfix(v 2.0.16) over to rhel 6 running postfix (v mail_version = 2.6.6). ive tried to make sure all the files are of correct permissions and that the main.cf file is configured corectly. However there is something wrong as when i run postfix: service postfix server i get no error but when checking the status:service postfix status i get: master dead but pid file exists Looking into /var/log/mailog i find this line being the issue:
Feb 25 16:24:39 puny1 postfix/master[3517]: fatal: fifo_listen: create fifo public/pickup: Permission denied
I gather this is a file permission issue and ive tried to make sure the public folder in /var/spool/postfix is correctly set but still no avail.

I was trying to write a graph plotting program with c++. I need to convert the infix expression from user to postfix expression for quick evaluation. However, the evaluation of postfix is kind of interpreted, and thus kind of slow for evaluating huge number of values. Say if I plot an implicit function the penalty is quite huge. Is there a way that I can compile the infix expression from my running graph plotting application for high speed evaluation.

I am attempting to use sendmail out of the box in fedora 12 (maybe my first mistake? Is there anything which needs setting up?). My impression of how to use this (based on tutorials on the internet and reading the man page) is that you do something like the following:
[Code]...
I don't really know if this is right, but I can't find any sites that say otherwise. This is based mostly on looking at a couple bash scripts I read, which seemed to do this. Obviously, however, this doesn't work. Is there anyone out there who knows what I'm doing wrong.

I am trying to setup sendmail on a fc10 box with dovecot running imap. I have everything configured and running on the server. For example, when I run "echo 'test' | mail -s test user@mydomain.com" or even to someuser@gmail.com, the mail goes through just fine. I can then reply from both of those accounts back to the server, no problem.
Relaying denied Cannot send mail. The SMTP server does not recognize any of the authentication methods supported by Entourage. Try changing the SMTP authentication options in Account settings or contact your network administrator.

I'm currently running a server at home with F13. Now I've set up my sendmail config to relay through another server because my ISP blocks outgoing email. Now recently I've noticed that they have stopped this server from relaying emails so i need to sort out another way to send out.My current sendmail config has this added which was the relay server i was using.
# "Smart" relay host (may be null)DSrelay.02broadband.co.uk
Now i either want to set up the server to email through my main ISP using a username / password or go through my main email provider Gmail.Any ideas on how to set up either on Fedora? I've seen guides for setting up gmail but never anything related to Fedora and I'm a bit stuck

I updated sendmail during a routine set of updates. I found it replaced my old sendmail with sendmail+tcpwrappers. I had to create an entry in hosts.allow as my hosts.deny was set to deny all. Never had to do this before, but I had not updated sendmail in a while. Just a heads up in case anyone else is about to perform updates.
