Mail Server not working internally behind pfSense firewall

Thanks for the responses guys.. I don't think anything needs to change on my dns server because when I use my old Cisco ASA, everything works fine.  I think it's something on the firewall that needs changed.

Hi Everyone,
I just purchased a pfsense firewall and everything is working correctly, but when I'm connected to the internal wifi, my phone can't connect to my internal exchange server. When I am off wifi on the verizon network all is well.
Can you help with what I need to setup on my new firewall to access my exchange server on my phone internally?
Thanks!

    why my outgoing mail server not working after ios 6 upgraded

    Ask your carrier to send you the settings over wifi and then install them that way.
    I'm on giffgaff and I used the giffgaff app from the store to sort this out.
    Overall though I must say Apple has let itself down on this as why isn't something written in the ios script that keeps the original settings??
    Very Poor indeed and I held off using Apple products for years for this very reason!!

  • Yahoo outgoing mail server not working.

    My yahoo outgoing server not working on iPod touch or iPad it says apple.smtp.yahoo failed...incoming is ok so far...this outgoing mail failure just started about a couple of days back....anyone else having this problem?????what should I do?rediffmail account does not get set up either so just unable to use any of my emails. :(

    Hello, and welcome to the Discussions.
    I get 100% success pinging mail.adelphia.net, and if at your home venue where Adelphia is your ISP, then I think no separate Authentication is required. Port 25 would be the proper port. However, if you are not at home, and the provider of internet connection limits you to using only authenticated SMTP then you would not able to use mail.adelphia.net as the Outgoing Server.
    Are you at the venue where Adelphia is the ISP?

  • Mail server not working after upgrade

    After a few hours, my server finally came back up however mail is not working.
    In the /var/log/mail.log I see many error  messages related to the same thing from Postfix whenever an inbound mail is recieved.
    May 24 06:26:22 my.server.com postfix/postscreen[25712]: CONNECT from [62.13.138.73]:64283 to [192.168.0.3]:25
    May 24 06:26:22 my.server.com postfix/postscreen[25712]: fatal: error seeking /Library/Server/Mail/Data/mta/postscreen_cache.db: Invalid argument
    May 24 06:26:23 my.server.com postfix/master[54]: warning: process /usr/libexec/postfix/postscreen pid 25712 exit status 1
    Help!

    I'd guess that the postscreen database is missing or corrupt.
    please issue the following Terminal.app commands:
    postconf -n -c /Library/Server/Mail/Config/postfix/ | grep -i postscreen
    postconf -c /Library/Server/Mail/Config/postfix/ | grep -i postscreen
    and anonymize the output if and as desired.   If you anonymize, please consistenty replace the domain portion of your URL(s) to example.com, example.net and/or example.org (these are RFC-reserved bogus domains) and replace the server's host name to something else if that's more sensitive than "mail" or "www" or "server" — consistency in these changes is important — and alter any IP addresses included (other than 127.0.0.1 / localhost) to 10.20.30.40 (or some other private IP address — again, consistency in these changes is important — and then post that output here.
    Before making any changes, get a complete system backup or two, on an external disk.  That's your path back if something here goes badly wrong, weird or otherwise untoward.
    Once there are complete backups and entirely as a test / guess / experiment, I'd look to rename an existing postscreen database out of the way and see if a new cache database gets created, and would also check the file ownerships and protections of the files in that area.
    $ sudo ls -ale@ /Library/Server/Mail/Data/mta/
    Password:
    total 48
    drwxr-x---   5 _postfix  mail     170 Jan 30 15:20 .
    drwxr-xr-x  13 root      wheel    442 Jan 28 10:57 ..
    -rw-------   1 _postfix  mail      33 May  5 16:08 master.lock
    -rw-------   1 _postfix  mail   16384 May 24 08:22 postscreen_cache.db
    -rw-------   1 _postfix  mail    1024 May 24 10:04 prng_exch
    $
    The two files that are most interesting in the above are the . and postscreen_cache.db files.
    There is also an upgrade log around, and you'll definitely want to have a look in that — to see what (else?) went wrong here.  (Off the top, I don't recall the name of the upgrade log file.  In recent releases, it's usually something like /var/log/install.log — also check the system logs for "upgrade" messages.)

  • Suddenly outgoing mail server not working!

    Out of nowhere, I am all of a sudden having problems with my outgoing mail servers. Most of my email accounts are through AOL, so based on which screen name I am emailing from, the outgoing server as always been smtp.aol.com:username. But lately, when sending mail, I get the drop down "try a different outgoing mail server warning. My internet service is through Comcast, so if I change the outgoing mail server to smtp.comcast.com, the mail will send. But why has this problem popped up? Did Comcast change something? AOL? Thanks for any help anyone has!

    I have got a similar problem. Mail has never worked properly - I can receive emails but not send them, Although the data for the smtp-server is absolutely correct and so is all rest password etc. - I've also tried other ports but they didn't work either. It can't be my computer or some firewall because Entourage, the microsoft mail-programme works perfectly well. After having had constant trouble with my PC, I bought this mac 2 months ago - and now I'm having more problems. Is there anyone who can give me a hint of what to do? Thanks.

  • Me outgoing mail server not working from iPhone / Reply to email address

    Hi, I have MM sent up on my iPhone and Mac, the SMTP outgoing mail server does not work from the iPhone but does from the Mac, to get around this I changed the outgoing server on the iPhone to my optusnet outgoing server, that has been working fine, the problem I have is if someone reply's to a email from the phone it gets bounced back becuase the reply to email address for me is @mac.com not from @me.com
    I have tried to change the reply to email address in the phone but it only allows you to change the name not the @mac.com
    I have only ever had a Me account not a .Mac account so I dont know why its locked to @mac

    I deleted the MM account on the phone and reinstalled it again. Now it is working.

  • Adelphia outgoing mail server not working

    I have been trying for the last week or so to get my adelphia mail to send from Mail. I can receive mail no problem, but the outgoing mail server does not work. I have the settings as such:
    outgoing server: mail.adelphia.net
    server port: 587 (also tried 25)
    SSL: off
    Password: none
    The error that I get is that port 587 times out. When I switch it to port 25 I get "This message could not be delivered and will remain in your Outbox until it can be delivered.
    Verify that you have addressed this message correctly. Check your SMTP server settings in Mail Preferences and verify any advanced settings with your system administrator."
    I made sure my password is correct in keychain as well.
    When I run a tracer route to find the ISP I get " gig2-1.clmascspv-rtr1.sc.rr.com, cable6-cha.edge.aol.com, son4-1-2.rlghncrdc-rtr3.nc.rr.com " as #2, 3, 4. I have tried to use these servers, but with no success.

  • HT1338 outgoing e-mail server not working since upgrade to mountain lion

    unable to send mail on one of my e-mail accounts since upgrading to mountain lion

    I had this problem as well after upgrading to 10.8.
    For all e-mail accounts SMTP servers seemed to be unavailable to Mail, regardless of setting TSL/SSL on or off. It turned out, even Thunderbird was unable to send any mail.
    After trying every hint on this forum twice – and to no avail; I found the culprit to my problem. Upgrading my iMac to Mountain Lion had changed the name, that my machine was using in my home network. The new machine name had "(2)" added to the old name. The brackets seem to have disturbed the SMTP servers I use. After changing the name back to anything w/o special characters I was able to send mail again.
    Very strange, since no error message lead to this direction, and only the SMTP was affected, everything else on the internet worked like a charm.
    So if you run into this problem, and no other solution works for you, make sure your LAN-name is not including any special characters, just letters, numbers and "-".
    Mind you: the name I am relating to is not necessarily the one you give your Mac in System Preferences > Sharing. It is the name your home router derives from that name. I am using a Fritzbox as a router and DSL modem; and had to access its web interface to check the actual name that my iMac was using to communicate to the web. That's also where I had to change the name back again.
    Don't know why ML caused the name to change in the first place, maybe the whole thing was unrelated and purely incidental to upgrading to 10.8. Using another router your mileage may also vary. You may still give it a try.
