subject: newbie config main.cf to send mail thru router to internet
Hope someone can help me with the postfix configuration file.
I want to mail from Linux logged in user accounts to the internet
and more importantly from Korn shell scripts to the internet.
so scripts running by cron could email error situations to people at home.
I do not want to receive any email from the internet to linux logged on
users
via postfix. (postfix mail between users logged on to the RH linux works OK)
I use Thunderbird for my email from internet.
I installed postfix from my Red Hat release disc:
mount /dev/cdrom /mnt
rpm -ivh /mnt/Server/postfix-2.3.3-2.x86_64.rpm
I have uploaded my main.cf & /var/log/maillog files from 2 tests
trying to email to o...@uvsoftware (my mail adrs at my ISP webfaction.com)
See 4 files in postfix/ subdir on my website:
1. www.uvsoftware.ca/postfix/main.cf <-- my postfix config file
2. www.uvsoftware.ca/postfix/maillog1 <-- /var/log/maillog test1
3. www.uvsoftware.ca/postfix/maillog2 <-- /var/log/maillog test2
4. www.uvsoftware.ca/postfix/postfix_chk_ps <-- chklevels & ps for postfix
The only thing I changed in /etc/postfix/main.cf was relayhost about
line 320
relayhost=[74.55.86.74] <-- smtp.webfaction.com
I am using a router to get to the internet & my ISP
- router gateway adress to the internet is 192.168.0.1
- my linux Red Hat computer is 192.168.0.4
For each test I did following:
1. service postfix stop
2. > /var/log/maillog
3. service postfix start
4. mail o...@uvsoftware <-- my email adrs at my ISP webfaction.com
5. service postfix stop
6. capture 1st test log as maillog1 & 2nd as maillog2
In maillog1 I saw 'No route to host (port 25)'
and thought my router firewall might be blocking,
so I set my router to DMZ for my linux computer 192.168.0.4
& ran test2 to create maillog2, but I still see 'No route to host (port
25)'
- not sure what is causing this ?
Note - I saw 'sendmail' msgs on some of the maillog lines (mostly 'postfix)
- to prove sendmail is NOT running and 'postfix' is running,
I captured results from 'ps' & 'chkconfig' into the 'postfix_chk_ps'
(ps/grep for sendmail & postfix, chkconfig --list sendmail & postfix)
Hope you can help me with the postfix configuration.
Thanks, Owen
