Server :: <Mail From> Header Not Working PHPMailer With SMTP?

Apr 12, 2010

Installing PHPMailer v.5 (server running php5) with SMTP function. I have installed the main files in mail directory such as: # class.phpmailer.php: This is the main class file which contains the various email functions.# class.smtp.php: This additional class allows SMTP authentication.I don't think I need class.pop3.php as I'm sending mails server side (smtp)and should be accepted by most IP's pop3 servers.

All my mail functions work great with SMTP and I can send and receive. My problem is that my recipients only receive mail from admin@domain instead of "My Website Name" Sounds simple enough, I know and I have made adjustments to class.phpmailer.php and have inserted my specific mail attributes for my site such as mail address, mail from, smtp server, user/pass for smtp,etc.PHP Mailer v5.0 class.phpmailer.php is a very long script and I only found a couple of places to put the FROM address as follows:

PROPERTIES,
PUBLIC
/////////////////////////////////////////////////
/**
*
Email priority (1 = High, 3 = Normal, 5 = low).

CentOS 5 Server :: Sending All Internal Mail To The ISP's SMTP?

Mar 27, 2009

I'd like to have anything that tries to send mail locally on my machine (including crontab reports for instance) to be handled by my ISP's smtp server instead of my machine acting like it's own SMTP server. I've spent around 15 hours trying to figure out how to do this and I keep either getting into things that I don't understand, or hitting brick walls (for instance, I found nullmailer, but after installing it, it seemed like it would only work on Unix) Is there an application like nullmailer which I can use as my MTA to forward all internal mail to a different SMTP?

Server :: Round Robin / Exim4 / Mail Delivery SMTP?

Apr 30, 2011

Here is the senario...

2 round robin dns servers
x.x.x.1 mydomain.com (hostname)
x.x.x.2 mydomain.com (hostname)

My problem is that when I try and send an email that is part of the domain, it ends up trying to deliver it locally. I realize it is supposed to, but I don't want that for non-users of the server.

I want to be able to deliver certain emails []@mydomain.com remotely. (info@mydomain.com)

exim4 setup "internet site; mail is sent and received directly using SMTP". This works well as long as it is not an email from mydomain.com.

Is there a way to have exim check the users first and then deliver based on local user or not?

Next question. Is having the domain name as the hostname the best way to setup a round robin? (web server)

Server :: Mail Server Migration - How To Deliver Locally AND Forward Mail To New Server

Jan 21, 2011

Can this be done? A company is currently running a postfix mail server. They got a new server and, while the users are migrated, they need to have the messages delivered on BOTH servers.

I thought it could be easily done in postfix: deliver locally AND forward mail to new server, but all solutions I found would deliver the messages in just ONE place.

Networking :: CentOS Mail Setup - Sendmail Via External SMTP Server

Jul 30, 2011

I am setting up a CentOS box as a NAT firewall that needs to also send mail. It needs to send this mail using an outside provider's SMTP. The provider requires SMTP over SSL. None of the machines inside the NAT will ever send mail except via the provider's SMTP nor will they ever receive mail except to local clients via the provider's IMAP servers.

So for the example the machine is TESTMACHINE. There is one internet facing ethernet port connected to a DSL modem via pppoe.

The SMTP it needs to send mail via is mail.host.net which requires SMTP over SSL (port 465) and username/password authentication.

The sendmail documentation is quite confusing on how to get this simple setup operating, so an example showing the appropriate changes to sendmail.mc and other require config files.

Server :: Sendmail SMTP Send Doesn't Work With OS X 10.6 Mail.app Clients

Aug 3, 2010

I've been having this problem since 10.6 released, but have until now been successful with the "just use Thunderbird" response. My sendmail server hasn't been changed, but as clients upgrade from OSX 10.5 to 10.6 suddenly mail.app will no longer connects to send SMTP messages through the server. (IMAP connections to the same server using the same user/pass combinations work perfectly) When I look at the logs, things basically stop right after the STARTTLS command.

Google indicates alot of people are having similar problems, but I'm not seeing any solutions. Do any of you administrate sendmail servers where some of your clients are using Apple's Mail.app on Snow Leopard, and if so what settings are you using? At this point, I'm happy to make changes to the server to accommodate Apple's issue, I have too many Mac users connecting to my server. I just can't figure out what to change. I've enabled virtually every possible login authentication combination, and none of them work.

Ubuntu Servers :: Setup An Outbound SMTP Mail Server With & Using Multiple IP Addresses

Mar 15, 2010

This is the current setup that we have: We have approx 20 clients who pay us to send out a type of e-mail called an E-Blast to their customers. We currently are using 5 Microsoft Windows Virtual Servers to do this. The problem is that those machines are starting to break down. There are times that it will take Microsoft Windows approx 9-10 hours to complete 1 job. This is way too long. We want to move away from Microsoft Windows for this particular type of job as it seems there are more customers who are wanting to use this type of advertising.

It seems that using a Linux Server "Command Line or Shell" environment would be the best way to go as there is no GUI like Windows. Since there is just text...that is something that would/should process very, very quickly.

I am in the process of setting up a new SMTP outbound mail server. This is the current software & configuration (what is installed on this new machine):

All of the customer data (Names, E-Mail Addresses, etc that these e-mails are going to) are currently loaded in a Microsoft SQL Database.

My machine that I am using is plugged into the DMZ. I have 1 ip address for the 1 network card. I have also added/bound 4 more ip addresses to that network card.

I have configured Postfix for Multiple IP Addresses.

I can, from the command line, send successful test e-mails and receive them in my personal account.

As far as I know everything is setup correctly. I can and will post requested information so that it can be verified that everything is setup correctly.

Here are a couple of my questions:

Ensure that I have my Network / Interfaces file and my Postfix's Master.cf/Main.cf files setup correctly?

How can I setup this server to be an Outbound SMTP server and get it to use all 5 of the IP Addresses to send these e-mails quickly?

What can I use to check and ensure that this server is in fact sending out emails on all 5 IP

Addresses (I heard that there is a program named "Postal" that may help in determing this).

Server :: Forward Root Mail To External Account Requiring Smtp Authentication?

Nov 3, 2010

I have one Centos Server and I want to forward root mail to 1 external account: [URL] I installed sendmail and created /root/.forward with this content: [URL] and I sent a test mail with this command: /usr/sbin/sendmail root <prueba.txt But nothing was forwarded.

After that I ran the same command with the verbose option:

/usr/sbin/sendmail -v root <prueba.txt

And this is the output:

root... Connecting to [127.0.0.1] via relay...

220 localhost.localdomain ESMTP Sendmail 8.13.8/8.13.8; Wed, 3 Nov 2010 21:09:39 -0600
>>> EHLO localhost.localdomain
250-localhost.localdomain Hello myfriend [127.0.0.1], pleased to meet you
250-ENHANCEDSTATUSCODES

[code]....

For some reason sendmail tried to connect to example.com smtp server and couldn't reach it. I am sure this is because the smtp server for example.com domain is not example.com is mail.example.com. Besides mail.example.com requires authentication, username , password and the smtp port is not the default 25 is 9999. configure sendmail to forward root mail to a smtp server that requires authentication, username, password with a not the default 25 port?

Software :: Mail.rc For External SMTP / Mail.rc Is Working Correctly?

Jul 1, 2010

I am running CentOS 5.5 and am trying to get Nagios to send out Emails.

After a bit of reading I have the following in my /etc/mail.rc file:

Code:
[root@linux ~]# cat /etc/mail.rc
set ask askcc append dot save crt
ignore Received Message-Id Resent-Message-Id Status Mail-From Return-Path Via
set smtp=172.29.1.76
You have new mail in /var/spool/mail/root
[root@linux ~]#

I have Nagios setup correctly and introduced an error to generate an Email but nothing has come through.I suppose I have two questions:

1. Is mail.rc setup correctly?
2. Can I test to see if mail.rc is working correctly?

CentOS 5 Server :: Configure A Mail Server Over A Home Internet Connection?

Feb 12, 2009

I have one server at home, connected through a router that gives me a static IP:192.168.1.2 - My PC192.168.1.3 - CentOS serverI enabled the port 80 into router forwarding system and I can connect properly to CentOS server, using the IP my internet provider gives me. My router automatically forwards a changed IP to my dyndns.com account so I can also access the server through a domain name (I pay to have it linked to one of my domains).My next step is to configure the mail server (dovecot) , so I can send emails from my local server(192.168.1.3).I was wondering if anyone has any tutorial links or tips to have the mail server configured through a home internet provider + home router.
