Question postfix with dynamic ip config


heres the situtation, id like to setup my postfix using the following setup

my box ip config: dynamic
free dns acct: jay1.sytes.net
my localhostname: jay.madcat.org

ive read around somethings about this email servers, but most of them are setup for lan and static ip configurations, so im looking for a good straight forward guide or even may be someone could help out here on configuring postfix using dynamic ip (www.no-ip.com) configuration...

It's not nearly as bad as it would seem. As long as your client for your dynamic host works (meaning when your IP changes it updates your DNS provider - noip.com) then you would set it up just as your would a static as there isn't any standard calls to your IP but rather to your domain which is NOT static

Some info that might be puzzling:
$myhostname
You get from opening up a console and typing:
hostname
It'll report back what your hostname is. If it's nothing, you can set one up, or just leave it blank, that's for your own internal network, no worries. Follow it with your domain, so if your hostname reports back as 'localhost' then:
$myhostname = localhost.jay1.sytes.net

$mydomain
Is the domain that you've chosen to use with your dynamic IP service. So:
$mydomain = jay1.sytes.net
is your domain.

You'll also wanna setup relaying for your local network, but the Postfix docs are pretty good about covering those things, as well as other threads on it around here

Cool

Great! Glad I can help

Good Luck, and have fun! It's a great mail server, and has A LOT of potential should you want "more" out of it.

Cool

Send/recieve some mail

Or, if you'd like, post it up and someone will probably take a look and let you know.

Cool

ok, tnx so much masterC.... now my goal is too "ONLY" send email to the outside world, nothing fancy. etc...

(ive followed some guide on http://www.mandrakeuser.org/docs/con...il2.html#scen2 ...)

my main.cf is "fresh" / "untouched"

givng "postconf -n", results are...

alias_database = hash:/etc/postfix/aliases
alias_maps = hash:/etc/postfix/aliases
command_directory = /usr/sbin
config_directory = /etc/postfix
daemon_directory = /usr/lib/postfix
debug_peer_level = 2
delay_warning_time = 4
inet_interfaces = localhost
mail_owner = postfix
mail_spool_directory = /var/spool/mail
mailbox_command = /usr/bin/procmail -Y -a $DOMAIN
mailq_path = /usr/bin/mailq.postfix
manpage_directory = /usr/share/man
mydestination = $myhostname, localhost.$mydomain
newaliases_path = /usr/bin/newaliases.postfix
queue_directory = /var/spool/postfix
readme_directory = /usr/share/doc/postfix-2.0.6/README_FILES
sample_directory = /usr/share/doc/postfix-2.0.6/samples
sendmail_path = /usr/sbin/sendmail.postfix
setgid_group = postdrop
smtpd_banner = $myhostname ESMTP $mail_name ($mail_version) (Mandrake Linux)
unknown_local_recipient_reject_code = 450


then, ive check using

#echo test | mail jay_820@hotmail.com -s test2222

then checking errors

/var/log/mail/info
Aug 10 13:19:40 jay postfix/smtp[3818]: connect to mx1.hotmail.com[65.54.254.129]: Connection timed out (port 25)
Aug 10 13:19:45 jay postfix/smtp[3818]: connect to mx3.hotmail.com[65.54.254.140]: No route to host (port 25)
Aug 10 13:19:45 jay postfix/smtp[3818]: 7E7DC3095D: to=<jay_820@hotmail.com>, relay=none, delay=252, status=deferred (connect to mx3.hotmail.com[65.54.254.140]: No route to host)


also found some errors on

/var/log/mail/errors
Aug 10 12:54:52 jay postfix/local[20331]: fatal: open database /etc/postfix/aliases.db: No such file or directory
Aug 10 12:55:45 jay postfix/smtpd[20349]: fatal: open database /etc/postfix/aliases.db: No such file or directory
Aug 10 12:55:53 jay postfix/local[20350]: fatal: open database /etc/postfix/aliases.db: No such file or directory




i can see that its trying to send my mail on hotmail.com, but theres this mx thing which as of now i dont understand yet that keeps my mail defferred...(queued) and undelivered...
(sorry for my poor enlish)

anyone can give me any suggestions?????

For the aliases error run:
postalias /etc/postfix/aliases
And then:
postfix reload

That should curb that error. As for the hotmail error, see if you can send to other mail accounts, there have been some issues with Hotmail and AOL lately...

Cool

You're welcome, if you need a mail account to test you can use me:
masterc AT masterc.no-ip.org

I don't refuse mail like AOL/hotmail might

Hmm..

Any chance you know if your ISP has blocked port 25? You've got DNS working fine, that's my IP, but the port doesn't seem to be able to talk.

Cool

tnx a lot masterC.....

hmmmmm..... i have been to a webpage w/c test if my port 25 is block or if sendmail or other mail server will work on my box, but upon testing my box, it failed... but then, ive done a little test on my own, by changing "inet_interfaces = all" on main.cf, then telnet my IP add(ppp) on port 25 .. and it let me in.... well , actually, i really dont know if that test is enough..

but then we could always change the port which we could listen or use right?
