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 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'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:
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 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..
im just wondering is it possible to instruct mailx to use postfix instead of sendmail while have sendmail and postfix installed? like system-switch-mail way in other distros. basically i would like to be able to use mailx when i uninstall sendmail and keep postfix only installed, so i dont get msg after i press . to send email from mailx
Code: /usr/sbin/sendmail: No such file or directory
I'm running Postfix in slackware 12.1. The mails are stored in /var/spool/mail/username. When a user's mailbox size got more than 200MB, the user can't check their mail. when it happend the log shows:
Apr 4 10:04:11 ns1 popa3d[2391]: Authentication passed for userX Apr 4 10:04:11 ns1 popa3d[2391]: Failed or refused to load /var/spool/mail/userX
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 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 postfix as spam Mailscanner to protect my mail server running sendmail. The problem is that when I forward an email from MailScanner mail me back with the following error:
<postmaster@localhost.@mydomain.com.>... Real domain name required for sender address (in reply to MAIL FROM command)) Jul 27 13:15:59 smtp postfix/local[28465]: C68AC1000001: to=<root@smtp.mydomain.com>,
make install then i got this error: postfix: fatal: chdir(/usr/libexec/postfix): No such file or directory make: *** [install] Error 1 I don't understand why it's checking the usr/libexec folder for the daemons although I've set the folder to /opt/product/postfix-2.6.5/libexec in the makefile. Here is also the cat of my makedefs.out:
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:
Can't send mail: sendmail process failed
Here's the last line from dmesg (the only one applicable, according to the timestamps and message content):
Code:
[484114.608378] sendmail[17975]: segfault at 0 ip b7dbbbf3 sp bfb0dc4c error 4 in libc-2.11.2.so[b7d44000+14e000]
Here's my ssmtp.conf:
Code:
# # /etc/ssmtp.conf -- a config file for sSMTP sendmail. #
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.
is there any HOWTO for configuring Webmin Postfix server with multiple postfix virtual hosts? Seems to be a tough challenge to set it up without any easy manual..
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:
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 have a apache server installed on my system which I use for testing out stuff like wordpress and forums. I use the server for learning stuff only. I would like to know what do I have to do so that these blogs, forums etc can send an email when someone registers. I guess most of these use sendmail to send email. So how do I configure sendmail so that it sends email using my gmail address and smtp. Also I think there is a php mail option (or something called like that) that allows us to send email without having sendmail installed.
Been using the Amazon EC2 Linux AMI and enjoying it.It comes configured with sendmail. I think I'd rather use postfix.replacing sendmail with postfix might be as simple as what I found searching online:
$ rpm -e sendmail $ yum install postfix.
However rpm complains:
$ rpm -e sendmail error: Failed dependencies: smtpdaemon is needed by (installed) mdadm-2.6.9-3.7.amzn1.i386
I am in need of configuration settings and steps for sending mails from linux server to some other domain or network. I need to send mail from linux system to my mail id.
Can connect to our mail server using telnet onto port 25 and this works correctly, 'ehlo whatever' shows output as expected.
However using a mail client to connect it gives an authentication error and the following appears in the maillog file;
did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA
what to look for in the config, this works correctly on our development box but not on our production server. Could it be another program is interfering with the connection?
Sendmail is running in standalone mode not through the xinetd daemon.
I am using the PLAIN AUTH method as to try and avoid getting more errors.
