I want to setup sendmail using my username and password on my ISP to be able to send out messages.This is actually true as the mylocaldomain is not a public Internet domain. Just a localdomain for our local network. However, I was expecting that to change to the username in my authinfo "myusername@myispdomain" since this account is authorized to send out email with my ISP.

View 7 Replies View RelatedIs the term a 'simple SMTP relay' a contradiction in terms?!I have an elderly Dell server on which I have just made a fresh install of 10.04 LTS server. I had 8.04 running on it for a long time, but I haven't tried an SMTP server before. It is a headless server with CLI (no GUI) and the latest version of Webmin installed.I have a basic LAMP server installed for a few websites using PHPbb and Joomla, and also I run a Mediatomb server for our household. When I installed I also chose to install mail services, but these remain masked behind NAT at the moment
I now want to set up an SMTP relay server so when I am working away and using different wifi points or my notoriously unreliable 3G dongle I can always send emails through the home server (from my iPhone and my laptop) rather than having to look up the SMTP server for each ISP of the place where I am working.
What I want is an authenticated server which takes my email and redirects it to my home ISP's SMTP server. I need only 3 authenticated users to have access (myself, my wife and my son). I don't need (or want) any incoming mail services at all.
Useful modules installed are: Dovecot, Postfix, Procmail mail filter, PAM - but how do I set them up?
Is there any simple setup that I could do, preferably through Webmin, but I can handle CLI if necessary?
I have looked at the Ubuntu help pages, but it looks so complicated to set up something that seems like it should be so simple to me.

View 1 Replies View RelatedI've got a server set up with Debian. The problem is that my ISP doesn't allow usage of port 25 (as I understand a lot of ISP's don't).I have PHP scripts hat use the mail() function to send e-mails through the Sendmail application.So, my question is: How can I relay messages sent to sendmail to an external SMTP server (like Google Mail, for example)? Would this be easier to do in the PHP configuration, or on the Sendmail side of things?I've used PEAR extensions in PHP to achieve this before, but scripts downloaded from the Internet generally just use the basic mail() function, and it would be a real pain to modify them all.

View 3 Replies View RelatedI 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.
I've tried googling this, and am having trouble finding something that doesn't end up being dizzying or confusing.
I was wondering if anybody could provide me with a concise, conclusive answer/guide.
I have a set of servers which require redundant SMTP relay. The first two of their SMTP relays are their own SMTP servers, and as such, are not dependable in the event that their network/servers go down. Their monitoring software runs on their machines as well, and uses the SMTP servers they themselves host.
I need to set up an external SMTP relay box that they can use to relay their monitoring alerts/admin notices in the case that their mailservers go down.
I have a company exchange server with pop/imap support @ my disposal but, unfortunately, that box runs Windows and does not permit any changes to services or additional software to add for the purposes of relaying clients.
So now, I need to create a dedicated linux box that can act as a relay to send email coming from the monitoring/admin/alert software in case their first two smtp servers have gone down.
When you set up a webmail solution these days, either on your home LAN or at a small business. What steps do you take to make the solution as secure as possible? A couple of years ago it was sufficient to port forward both port 25 and 80/443 to you server located on the internal LAN. Today you're more likely to have a SMTP relay in a DMZ of some kind. But the webmail, how do you solve this? Do you place a dedicated webmail frontend in the DMZ and open ports towards the internal LAN, or do you just place the entire server in the DMZ? I'm looking for input for a small network/home LAN so it shouldn't be to complex.

I travel around a lot with my laptop, (also Ubuntu 10.04). However, my ISP does not allow me to send email via their SMTP when I am not in their IP range.
Since I have this little server I am building, I thought it would be nice if I could have my own SMTP relay. The objectives would be simple:
- I do not need a mailbox or POP server (yet).
- I wish to send email from any place in the world. I can not use a filter on IP ranges or local networks only.
- If my server could do this, I just configure Evolution on my laptop to send mail to my home IP address, using some sort of authentication and/or security/encryption (whichever is easy to implement).
- My server then just forwards my mail to my ISP. Since the server is inside the IP range, it can be handled as usual.
I have been digging through several howto's and the ubuntu server guide, searching some forums etc. Even while I don't fully grasp the things explained, I can't get the idea that one of those is "Just what I need".
Even still, if there is some other service outside my own that can do this (a public SMTP relay maybe?) I would also be happy to consider as long as it is safe and does not "eavesdrop" on my messages.

On my opensuse 11.4 box (although I assume the version is irrelevant), I'm trying to figure out how to do something with the mail command. We have multiple smtp relay servers and sometimes I have to test to verify that mail is bouncing off of them successfully. On my laptop, in my main.cf file for postfix, I've got the relay server listed. But to test multiple servers, I have to change the main.cf, restart postfix, send message, and then repeat for each test.
I'm trying to figure out a way to specify the smtp relay on the command line. I've been playing with the -S option which is supposed to allow variables and one of the variables in the man page is 'smtp'. I've tried several different syntaxes but nothing seems to work.
The closest I've come is:
mail -S smtp 10.1.0.63 -s "test" user@email.com < main.cf
That syntax doesn't give me an error but it still routes the message off the smtp server listed in main.cf which is not 10.1.0.63.

As ASSP is a proxy, I need a server to send it to once ASSP receives it. I've tried my ISP, but this failed and they weren't willing to confirm if a connection attempt was received at their end.
Current setup
Inbound
mx -> router -> ASSP -> Exchange 2003

Exchange 2003 -> mx
I'd like to setup outbound as either
Exchange 2003 -> ASSP -> <ISP> SMTP relay
Exchange 2003 -> ASSP -> <relay running on Ubuntu eg postfix>
Can anyone help me with troubleshooting steps or a better suggestion for how I can set this up. I'd love to know why my ISP setup didn't work, but I don't know a tool for monitoring IP traffic in Ubuntu SE, in windows I use Wireshark is there any equivalent I can setup for Ubuntu or a tool I can use in windows which will show all traffic, Ubuntu and windows server are on the same netgear switch, not sure it's smart enough to copy all traffic to another port for monitoring.
