Hi All, I have set up three servers in a development environment. Via CR they're updated to Centos 6.2 It appears that these servers have postfix installed on them by default, which unfortunately I'm not very well acquainted with. All I want is a quick and dirty way to enable these hosts to send email through my own SMTP host. My (sendmail) SMTP host uses SMTP AUTH on a non-standard

...these?check on or off per check. - automatic checks for needed programs?and installs when not found. - installs all needed programs without any questions asked. - e-mail reporting when errors are found.? ( default only on errors found ) - if no sendmail program is found, installs postfix and sets relayhost for you if needed. ????postfix wil be running on localhost only ??? relayhost is not needed if you have a "correct" dns setup. - can run as cron job, if administrator password is suppied in the script. - run it without email address for console output only - asks for Administrator passwo...

...r updating it to 4.4 Before the update, I did not have any problems. My ISP requires that email clients must authenticate to their mail servers before mail can be sent out. I setup smtp auth to get postfix to relay mail through the ISP's mail servers. Here's my config: main.cf -------- relayhost = [smtp.broadband.rogers.com] smtp_sasl_auth_enable = yes smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd smtp_sasl_security_options = sasl_passwd --------------- smtp.broadband.rogers.com blah at blah.com:password I've done the usual run through of config files after an update,...

Is there an extra step which must be taken to get postfix to deliver email via a relay host when the postfix machine is pointing to an samba internal DNS? I did a test setup using a public DNS server and it worked. Same setup where the machine (Debian 9) is pointing to a samba DNS doesn't work. The errors in the postfix log seem to be DNS related. Thanks,

...ould crash or be down for maintenance or other reason. As far as sendmail, it is simple to switch off the sendmail daemon and only run the queuing submission agent: 1) edit /etc/sysconfig/sendmail and set "DAEMON=no" 2) edit /etc/mail/submit.mc and set FEATURE(`msp', `[IP.of.relayhost]')dnl and of course add an alias for root. Does anyone on this list have experience running a minimal MTA? What other options/software should I be looking at? Any other insights, suggestions or insights? Both the Dom0 and guests are CentOS 5.2. Thanks in advance, Brett

A long time ago someone helped me with setting up sendmail to simply queue and relay mail. They suggested: 1) edit /etc/sysconfig/sendmail and set "DAEMON=no" 2) edit /etc/mail/submit.mc and set FEATURE(`msp', `[IP.of.relayhost]')dnl Given the sendmail-cf RPM is already installed a "service sendmail restart" is enough to a light, direct submitting sendmail setup. How does one rewrite all mail to one specific address so it can be filtered by a user that receives all mail for this host? Can there be a rule i...

...ystems, including even commercial *nix groupware based systems like Zimbra, as well as plain mail systems like dovecot, or cyrus or courier. I know that many (if they are smart) Admins that do use Exchange internally will use postfix (or something else linux/unix based) in front of it as their relayhost (for both inbound and outbound), so just counting the number of publicly accessible smtp servers won't be a good gauge. Does anyone know of any decent non-biased studies that have been done, hopefully relatively recently (last few years) that provide such a comparison? Thanks, -- Best...

...utgoing (autoresponder) mails to the SMTP on IP 192.168.10.22. The postfix image is configured in a way that certain IPs are allowed to send mails without authentication. So on postfix side I am set. Currently I did a quickfix: I added postfix to dovecot image and configured postfix to use the relayhost 192.168.10.22 for mailing. This works, still I would prefer having the dovecot image not containing an postfix SMTP. Thanks Tom

I'm trying to understand how to deliver mail to an address locally which is popped from my isps email account. I access and keep these emails backed up on dovecot and use postfix smtp to deliver mail. The problem is that while fetchmail uses dovecot lda directly, postfix can't include my isps domain in its $mydestination because I won't be able to send mail to other users in that
