I would like to set up a proxy for SMTP traffic by this i mean send and receive mail through a proxy.
I have a machine which is not directly connect to an internet gateaway, I already have an squid proxy for http and https but now i need to send mail (receive is not fundamental)
Which tools do you advice me to use and if you have some doc or tutorial to use this tool as an smtp proxy it would be great. (I'm running on CentOS 7)
Thanks in advance

I would like to send alerts using a mailer in HAProxy.
I tried to follow:
email-alert
The problem is that my mail server requires a SSL connection with username an password.
Any suggestions?
Solution.
Following (https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-postfix-as-a-send-only-smtp-server-on-ubuntu-14-04) I've configured a local postfix.
HAProxy connects to this SMTP server to send mails.
I have a domain, a Console Application with OWIN self-host.
The Console app host on AWS EC2 server windows server 2012.
My mail feature of server is sending Verification Mail
I've google many owin mail send or receive infomation,
but all of them are smtp/pop3 on google or some other smtp/pop3 server.
Is it possible to do send / receive mail in a console with current ip or custom domain?
I've try method.
Use hMailServer:
No luck in this. can't send/receive any mail, and set gmail for add smtp and pop3,
but fail.
the error msg: "We were unable to locate the other domain. Please contact your other provider."
Use AWS SES:
Still fail on this.
AWS SES need vail domain with anyaccount#domain, but i have no mail feature on my server.
Use my gmail:
Connect gmail need SSL. I have no SSL.
And research hours for host ssl on OWIN self-host,
Is there other solution for this?
I set a DNS MX Record from my DNS provider.
Now,I can send/receive mail with hamilserver and gmail smtp/pop3.
not best solution, but my problem solved.
I set up a BOSH server using node-xmpp-bosh and configured converse.js (a javascript XMPP client) to use the BOSH url I set up, I tried log in with my jabber.org account on converse.js and all worked fine.
Now I need to make this work with a private XMPP server. Assume that the XMPP server is at chat.mysite.com:5222, a JID on the server is johndoe#mysite.com. How do I configure the BOSH server so that it connects to chat.mysite.com:5222 when I try to log in with johndoe#mysite.com on converse.js?
You should add DNS SRV record _xmpp-client._tcp.mysite.com which should point to chat.mysite.com 5222
Wondering if we have options for a failing smtp mail at "localhost" after changing DNS host.
The problem setup is this:
SMTP mail is being sent from a server, with mail being configured on the server itself. Originally, server was host of DNS domain as well as web app.
Using JavaMail, a request is sent to "localhost" without any authentication
The DNS settings have changed, server hosting web app is no longer the "from" email address
The Java web app cannot be modified and is still sending to "localhost"
Question: Do we have any options?
I'd like to intercept the "localhost" smtp mail request and forward it along to our domain's mail server, with new credentials, but am unsure if that is possible. A stand-alone script to watch for those requests?
We did receive the suggestion to edit our DNS settings on the new hosting and add "MX" and "A" records, but that would require a change of source code, which is not an option at this time.
Thanks!
If there's no SMTP server running on localhost, and you just want to redirect mail to another mail server without authentication, you could use a simple "proxy/tunnel" using something like the "netcat" program.
If there is an SMTP server running on localhost, you might be able to configure it to forward all messages to your other mail server.
Otherwise, is it possible to change the properties used by JavaMail in your web app, without changing the source code? For example, do the properties come from a file or from System.getProperties()?
I am looking for a little direction to my problem. Short story, I have a website hosted on a web server. I pay a yearly subscription. This year I am planning on taking it off and hosting it internally. I already backed up, restored, and installed all necessary components (on Windows BTW with IIS, PHP, and MySQL). The site works great internal and by IP address externally through a firewall. (IP address for now until my web host subscription expires, then I will forward and register DNS).
But now this is my problem, my website has email functionality which works on my providers server. I want to install a local mail server for my website that will wind up sending and receiving emails through my website. I am lost here. No sure which path I should take. I have installed and used Exchange 2003 in the past just for internal domains, nothing for internet AND internet.
Anyone with ideas, links, suggestions? I see that IIS does support SMTP virtual servers, is this a possible route? If so, what about POP3 or IMAP (incoming) server solutions?
Thanks
Edit
---Update On Situation---
So far I have configured a local exchange server that works with my local webserver. I then created a CNAME in my web host DNS zone for my IP address. I created a simple subdomain for my site redirected to my home web server. Everything works great, internal email through Exchange 2003 from website on IIS, redirected DNS names, almost there. Now I just need to create Internet Mail functionality in Exchange. Went through the Exchanges wizard to "open system" for Internet mail, created new SMTP connector and ....nothing for external mail test. Failed! Thought everything was configured properly. I also tried to open all ports on firewall, 25 and 110.
I'd recommend using something like PostMarkApp to send transactional email from the website, and use hosted email (Google Apps for Domains) for your email. Its a pain to run a real mail server.
Link to Exchange Internet mail SMTP connector configuration:
Configure Exchange Internet Mail SMTP Connector
Well, I did figure it out. I was on the right path and everything was working but I just configured my client wrong and my ISp blocked port 25, duh. CHanged port to unused 366. But here is a little tip for anyone that may need to figure this out in the future.
1)Setup install IIS with default SMTP and NNTP virtual servers.
2)Install Exchange into organization. Internal naming convention doesn't really make a difference between internal to externally if you are behind a firewall. Basically this means you don't have to create a seperate zone in DNS if using this for a seperate domain hosted elsewhere. Hope this didn't confuse anyone.
3)Right click on server name in Exchange System Manager and go to Internet Mail Wizard
4)If you want your clients to hold a different domain email address than your internal you can setup in exchange through
Exchange System Manager >> Recipients >> Recipient Policies
Then add a Masquerade in Default SMTP Virtual Server
5)Have a gmail Internet SMTP connector set to smtp.gmail.com as smart host with a gmail email account settings and TLS checked
6)Default SMTP VS set with outbound port 587 and TLS checked
If you need to change SMTP ports too, don't forget to change not just firewall but also inside Exchange.
