By the way, I finally got this sorted

I chose in the end to use sendmail fetchmail and qpopper. I had to force installs of some to get over some corrupted or semi-complete installs but when they were in they configured easily with Webmin

Thanks for the pointers

Have you relaod your postfix?

EvilOne,

only 16 hrs?!!....yeah, I'm still in that ballpark too, with the mail server configuration....

the 2 issues which are remaining are:

#1.) inability to retrieve mail from using POP3 from clients....this goes for on the mail server itself using Netscape, as well as Windoze clients with Outlook Express.

#2.) outgoing mail is received by recipients with my domains address appearing as: [USER@.MYDOMAIN.COM] instead of the accepted [USER@MYDOMAIN.COM]


Let me know what you guys think....I'll be up all night (again) trying to work things out....

=========================================

I still can’t seem to get the client machines on the network to connect to the smtp server (postfix). My main.cf file is listed below but, is there anyway to see if it something else blocking them? Such as the firewall or a inadvertently closed port 25? My firewall shouldn’t be blocking anything on the 192.168.1.0 subnet so I am doubting that is the issue.

Main.cf

Hmm How try to edit /etc/postfix/access and put your network's ip, hostname, your domain like this :
/etc/postfix/access :

192.168.1.0 RELAY
yourhostname RELAY

save it and restart your postfix.

And also to check your /etc/hosts, /etc/hosts.deny
be sure that in your /etc/hosts.deny or /etc/hosts , you didn't blocked any IP escpecially your IP.

have you installed an smtp service? I found after many hours it does'nt come with postfix. You need to edit :

/etc/inetd.conf

and add or uncomment the line :

imap2 stream tcp nowait root /usr/sbin/tcpd imapd

that should sort you out

Ade.

joseph, you don't NEED to use that file,
he's used the mynetworks parameter instead in his main.cf file.

Success, success, success! One small step for newbies but a bloody giant leap for me! Bare with me while I do a happy happy joy joy dance! (Sounds of “happy happy joy joy” reverberate around the room)

Well, that seemed to work. I had an imap line in the inetd but not an imap2 line. The imap line didn’t do anything when uncommented. It needed the imap2 line. I can now send mail locally from any machine on my network to a user on the network. I now have to get the system to relay to my ISP’s smtp server that requires authenticated smtp. Any suggestions? I have seen that you can specify for authentication for client systems but what about the smtp you relay to? Mine requires authentication.

lmao @ the happy happy joy joy dance... Never thought i'd hear that again.

Sorry but for authenticated smtp i've not a clue lol.

I pay www.dyndns.org about $20 per year for their webhop relay service. For that i also get 2 backup MX servers that store my mail if my server happens to be offline. Take a look and see what you think.

Damn glad to see i was of help though, and many hours of headache's helped someone else lol.


Nice work my friend !!!

Ade

Hello - I have the setup you are asking about working - if you have any questions let me know and I can send you the config. We have a separate internal server that has web apps - a request form where users can request a userid and pw for new employees. You can separate them into groups and setup security based upon he group or dept. Let me know if you need specifics.

Thanks for your response. Please aware, this is an OLD thread. I orginally solved this issue with a day or so, back in 2003!!

Yes... I am trying to use Ubuntu and Postfix and ?? to do an internal (intranet) mail server config. Having some trouble making outgoing mail go to my ISP's (external) server if it is not destined for an internal user. Thanks for offering help!

sorry, macdafoe but I am a newbie as I see you still are glad I was able to provide a laugh

to richmich:
this is my sendmail.mc config file - we are currently not using this config anymore since we switched to google apps. I would be happy to help anyway I can. I know what it is like to search for answers under a time crunch. Hope some of the parms I use can help you to determine what you need. Let me know how you make out
