Can't get emails
-
Hi. So just to get an idea, where is your roommate's mail server located? Is it being hosted on your LAN or is it hosted elsewhere on the internet? You seem to have a NAT rule which is port-forwarding POP3 to your internal network address (192.168.1.0/24), not a host address. This won't work for starters. For that matter, if your mail server isn't hosted internally I can't see why you would need to port forward any mail protocols from outside to inside.
For now, addressing the matter of your roommates' email issues only, can you first give an idea of where his mail server is located - inside your LAN or on the internet?
The web server is located from the internet. So the problem seems to not be the sending part, but the receiving part.

Web server? I thought your roommate was having problems with the mail server?!! Is he using something like Yahoo Mail or GMail?

I think you're looking at your local network when the problem lies elsewhere.

I'm more specifically looking at the PFsense box as a whole. What could the router do to prevent email from getting in. If it's not the problem, then it's not my problem.

He's using the more traditional e-mail. IMAP works fine. I don't know if SMPT or POP3 is having issues. Am I mistaken? Does the mail server not originate from the internet?

OMG. No. His MUA connects outbound (POP3/IMAP) and receives/pulls email. If he wants to send one his MUA connects outbound (SMTP) and sends it.

One reason mail might not be getting in would be because there was a rule on your firewall which prevented POP3 or IMAP from being allowed in. If you haven't got such a rule then the issue may very well lie with your roommate's mail server. Is this server managed by anyone? Has your roommate enquired with anybody whether the mail server is malfunctioning?
If you haven't changed anything on your firewall and your roommate's email has suddenly started failing then I would first check that the mail server isn't the issue before looking for problems at your end where there may not be any.

You mean allowed out?
That would make the MUA complain.

Now that you mentioned it, I decided to check my firewall and this came up in the search.
Would this be relevant in any way? -

The thing is that I do not know if it's sending. But I'm guessing a giant "Cannot connect to server" would pop up if that were the case.

Considering you blacked out anything useful, it's impossible to tell.
Email clients make OUTBOUND connections. The pertinent firewall rules are on LAN, not WAN. But like I have said at least three times, if it was a problem connecting to the server the email client would be complaining.
This is a non-problem. He needs to call his email provider and ask where his mail is.

Your screenshot has blacked out not just the IP addresses but the source/target ports, so it's not really much hlep.
Ok, now that we've established that your roommate's mail server is hosted outside your LAN, you should forget about port forwarding any protocols inbound. Your out-of-the-box outbound NAT/rules should allow your roommate to connect to his mail server without your having to muck about with inbound NAT rules.
You can try this test: From a command prompt (any machine in your LAN will do), type 'telent aaa.bbb.ccc.ddd 110', where 'aaa.bbb.ccc.ddd' is the IP address of your roommate's mail server. If you get a 'Connected' message that means your LAN can connect to the remote server successfully via POP3. Likewise with the other ports for SMTP (port 25) and IMAP (port 143). If you don't get a 'Connected' message this may mean there's a problem with the mail server. Unless you have a rule specifically blocking access to these ports then it's unlikely to be the firewall.

Might be worth showing us your firewall rules, for that matter.
The ports are 61109, which I know is not POP3, but I filtered the search to port 110.
As for rules, there are no firewall rules for the WAN.
Either way, thank you. I will ping the server tomorrow and see if it gets me anything.

Hey ,
I guess your friend has configured Offline client(outlook , windows live etc) on LAN PC .
In order to diagnose first you have to SSH into Pfsense and from Terminal do to a Telnet to MX of mailserver on Port 995 or 110 (this is configured on offline client) , are you able to do it?
