I'm trying to configure postfix so smart daemon can send out notifications emails. My system will need to send emails to a mail server that is on the same local network. I have not had much luck in getting this to work, and am confused on what I need to setup to do this and how to set it up. Does my system need to be apart of the same domain as the mail server? If so, how do I do this? Is there any restrictions sending emails from the command line as the root user? Do I need to configure a relayhost?
Basically all I need to do is send emails to a local mail server, i.e. a mail server on the same local network. I do not need to receive emails. I am rather clueless as to how to set this all up, and what I need for this basic email functionality. I have read and tried many postfix configuration tutorials, but when I try to send out a test email to a email address on the local network mail server I always get "Connection refused" to the server and deferred or bounced status on my test email.

i have a small issue, to make our network more secure, i now require outgoing email to require authentication. Now the problem..i have a automated mailer that does not have the option to authenticate. is there a way to allow a certain email address or the local network to send out without authentication? If i cannot do this for a single email user to allow them through with authentication, how would i remove the authentication paramaters in the postfix smtp..

View 7 Replies View RelatedI run my own home server using OpenSuse 11.1, everything is setup using apache, php, etc etc, and it all works perfect, but now I need to use my own email server for the use of Dolphin social networking software, so that when someone registers, the email server sends out registration confirmation emails, so I set up postfix, yeah right!!!, even though I followed all instructions to set postfix as a closed relay, a test done at mxtoolbox site still said it was an open relay, but while I was trying to set up postfix, my access to the server slowed down, and my servers drive light was constantly active,,, so when I look at the mail queue, I saw 4000+ emails, all from japan, (hinen.net), so I promptly shut down postfix and use postsuper -d ALL in the command console to delete the queue, but no matter how I try, I couldn't configure postfix as a closed relay,,, so I uninstalled it and installed sendmail, and using webmin, I could use a spam list and block the domain, now, sendmail's test at mxtools show as a closed relay, I can't even send out a test email using smtp auth, but disabling auth, I can, but now my IP is blocked at spam cop, and spamhaus,,, gmail server say my IP is not authorized to send to their servers, but to use my ISP relay instead,,, but my ISP doesn't have a relay,,hence the need to run my own email server.
My home server uses double layer firewall, a hardware firewall between the internet and the server, and a software firewall on the server, and I only allow the ports I need, IE, 80 = http, 443 = https, 20/21 = ftp, 25 = smtp, 110 = pop3. and that's all, but any other internal access from my workstation to the server, using ssh, I only open the ports on the server firewall. If someone here has a great deal of knowledge on sendmail, and can set up a an M4 (linux.mc) config file for me, it would be much appreciated. What I would like my email server to do, is to only allow the sending of emails from inside it's own server system,, ie, when a php script sends an email to the server, then the email server would let it through, but anything else, outside the local network is ignored.

I have a small internal network with about 8 or so servers or workstations. My mail server is getting spammed from all over to the root and other administrative accounts. I also get valid email sent to the root and administrative accounts from within my local network. Is there a way to block all email coming from outside my local network while still receiving it inside the local network to these specific accounts?

I need to setup a local email server. This mean, I send an email to admin@localhost and in thunderbird or any other program I receive it.
I need this to test a php script.
I want to create a shell script that generates a file and then sends it via email from my Ubuntu desktop by using my Exchange 2003 Server which is on a separate windows machine on my network. I do not have an smtp server set-up so that is one of the reasons I want to go this route. The other is because I will be able to sync the emails sent from the exchange server.

A question that I've asked myself (and google) many times but never got to an answer.Scenario:ServerA) postfix Primary MXServerB) postfix Backup MXAccording to the rfc a source mailserver can decide where to send email e.g.send an email to backup even is primary is reachable up and running.So my questions are: 1) how do I (live I mean) replicate messages arrived on any server to the other?2) How do I synchronise sent messages, message deletion, folder creation/deletion.Imapsync goes half way towards the solution but it needs to be run manually one off and you must specify source and destination.All I wanted really is a user to be able to use either server without having to worry about primary/secondary or what so ever.

I have installed Joomla on an Ubuntu 10.04 Server pc. The Ubuntu server is connected to my Novell NetWare network via static IP. I need the Ubuntu server to send mail to my mail server through smtp, my entire network has static IP's. The Ubuntu server does not need to receive mail only send, I have found that I could try use sendmail, postfix or exim4. I tried Exim4 but I am battling with the setup. For my situation what would be the best to use? What config's are most important to set?
View 2 Replies View RelatedI'm trying to write a script that will continuously ping a server and then send out an email when the server is down, and then when it is back up. Then, continuing with monitoring. I would like to not run this in cron, because I don't want to script to run with multiple instances.
For example,
Ping a server every minute.
-If successful, do nothing.
-If failed to ping, then send out email stating that server is down.
-Once ping is successful, then send out email stating that server is up.
I only want it to send an email once after a failure, so the end user isn't get an email every minute that it fails. Once it is successful, then send the email (one time), stating that the server is up. Then, continue to ping and if fails again, repeat the process.
My company email server has been working flawlessly for the last 5+ years. Recently, one of our clients put their email server behind a firewall (an assumption on my part; details below). Ever since, email sent from within the company (192.168.xxx.xxx internal address; all computers and server is behind a NAT firewall [Netgear FVX538]) is either being sent to the client after some delay (if email is sent using Outlook) or is being deferred until the messages expire (Thunderbird, Squirrelmail, etc.). Email sent to the client from anywhere outside the company (using Thunderbird, Outlook or any other email client) is also delivered without any problems (usually after a short delay).
All other emails to the World are being sent without any problems at all (both inside and outside the company; using any email client or webmail). I did contact the client's postmaster, but the client, being a large government agency, will probably not address the problem (if it is on their side) anytime soon. I am not sure if I can do anything from my end to solve the problem. Ever since the problem with the client began, I added two statements to the postfix configuration file (smtp_pix_workaround_delay_time = 20s and smtp_pix_workaround_threshold_time = 0s); this seemed to a bit - it reduced the delay for emails sent via Outlook to a few minutes (as opposed to 30+ minutes); emails sent using Thunderbird/webmail are still being deferred.
Server details: Dual quad-core processor machine, 32 GB RAM, dual 1 gbps network, running Fedora 14 (64-bit; loosely modeled along the lines of Perfect Server (with ISPConfig2) as described on the howtoforge website). Running Postfix (v. 2.7.1), Dovecot (v. 2.0.9).
Postfix details:
alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
body_checks = regexp:/etc/postfix/mbl-body-deny
broken_sasl_auth_clients = yes
command_directory = /usr/sbin
[code]....
I emailed the client's postmaster suggesting they disable smtp fixup. But still, what bothers me now is that Outlook works (both within and outside the company) while Thunderbird, webmail, etc. (used by ~90% of the users) do not. In addition, all email clients from outside the company can send email (authenticated via the company server) to the client without any problems. Is there anything I can do on my end to make non-Outlook clients work within the company (webmail is hosted on the company server; so, it would have an internal address as well)?
I just set up a new email server on Debian Lenny. It's Postfix for MTA and Dovecot for IMAPS server. I use Dovecot for authentication. I have two UNIX users on the system (except root), one was added before the installation of Postfix and Dovecot. I'm not doing any virtual things, just plain UNIX users and one domain on a dynamic IP. The first user, "webadmin" can send and receive emails just fine through the server from my mail client.
Now I just added a new user, "scarleo", and it turns out I'm unable to send and receive emails with this account. If I log in (SSH) with scarleo I can use bash mail to send emails, works fine. scarleo can also receive emails from webadmin and can connect to Dovecot to read emails. However scarleo cannot send or receive to or from anyone outside the server from my mail client. I have restarted both Postfix and Dovecot after adding the user. Do I have to do something else to make this account work like webadmin's?

In my Windows environment, I use email client such as Microsoft Outlook to connect to our email server to send email with the following configuration:
Incoming server (POP3): 995 - (requires with SSL)
Outgoing server (SMTP): 465 - (use encrypted connection SSL)

And the mail server requires user ID login and password.how do I setup a text command based email client in my Linux (Centos 5.1) to send out email through the existing email server above, which is in another machine? The email client has to be text command based because I need to use command line to send notification email from anothar application installed in my Linux (Centos 5.1) Since the email client will only be used to send email notification, I don't require setting up of an email server in my linux.
