Unblock port 25

I am runing a postfix email server at home. I need port 25 unblocked so that I can send emails in and out of my home network.

 

I have tested the email server, and I am able to send and recieve emails locally. My modem is bridged andon my router port 25 is forwarded to my server. So I know for sure port 25 must be blocked on my service.

 

I have already talked to tier 2 support and they said that this issue is outside of their scope. Keep in mind, I will have to cancel my service if this issue can not be resolved.

Port 25 is blocked on residential accounts.....

Recommend are either ports 465 or 587 with SSL

Unblocking is not a function of local tier supports, this requires going through the paid version of ConnecTech support.

Using a different port in not an option for me, however, I resolved the issue. Port 25 being block was just one of the problems. Thanks for your help though.

If nothing else, are there not third party apps you can use to reassign port numbers even if a particualr program has a set port number hard coded into it?

Seems i've read about that, and if anyone knows of them, if they would share it, so others can benifit, and not need to bother with the hastle of getting a particular port unblocked.

 

Seems like, some firewall programs can do manual port forwarding, if I am not mistaken.

 

Saddly, just don't know, but would sure like to.

You have to be kidding, right? I have the same issue, and you are telling us we need to pay a support service to unblock a port? I have delt with these support people before, and all they do is try to sell you a support contract. If you don't want that, it is about $100 to get them to do anything. So we need to pay $100 to have someone do what should be available to do at any time, and probably takes five minutes. I think it is time to change my complete AT&T Uverse service to someone else. I don't like it to be an official policy to rip me off.

@donmolinari,

It's not company policy to rip people off, the problem is that the lower tier supports are not familiar with this issue, they think its something that can be fixed in the customer router/modem and when it fails they send you to the premium support. Which is completely unnecessary. I went ahead and located your account t*****@***bell.net and removed the port 25 block. You may or may not have to reboot your modem/router.

Why does it have to be specifically port 25?  I believe you can configure postfix to use ports 465 or 587.  I did a google search of that question and there were hits suggesting the configuration settings.

 

As for port 25, yes, I believe they charge for opening it now (years ago they didn't).  But I thought the price was something like $49.  Maybe they raised their price.  Heck they raised prices for everything else over the years so I guess this may be no different.Smiley Sad

_xyzzy_,

 

Thank you so much for doing this. I am doing a programming project on an obscure platform that I have worked with for many years. There is only one SMTP server that works on this platform, and it is hard coded to use port 25. I spent a lot of time trying to fool it into using another port, all to no avail. After you opened this port, the first time I tired it, it worked!   Now I now that all the work I did is working, and I can specify to the end user that port 25 must be open. I know now that everything works with this condition. And I am finished! I completely understand your point about the first support level, and the need to go up. But, I think from your comment you understand the frustration of paying the premium fee to get the standard port opened. Since you work for AT&T,  I would suggest that the ability to use the standard port be an option in the advanced set up for the email account, or perhaps have an email to send a request to have it opened. Since other users here are requesting the same thing, it would seem a good idea, IMO. Again, I am very grateful for your effort.

Sorry, I sent you the message that I meant for ATTDSLcare. As you can see, I explained the situation there. I am aware that other ports may be used, and that ISPs change the port to avoid spammers. But, since port 25 has always been the standard port for an SMTP server, it is, I believe, a little difficult justifying a premium support incident just to open the port. A number of other users are saying the same thing here.

@donmolinari, in all honesty its really just a training issue and its a request they do not get that often if at all. And after doing this for 17 years I can certainly understand how they automatically think this should be done in the modem. So when they open 25 in the modem and it still doesnt work then they send you to premium support because "there must be something wrong with your computer/set up"... I have seen them replace modems over this issue.............. Don't get me wrong, I am in no means sticking up for them because at the very least this should be in their "script". But I can not change the system so I just try to right the wrong where and when I can. So I do apologize for the inconvenience as I can understand how frustrating the process of getting this far can be. 

 

For anyone else, I do suggest what @my thoughts said earlier:

"Recommend are either ports 465 or 587 with SSL 

https://www.att.com/esupport/article.html#!/email-support/KM1010505"

But if 25 is the only option then shoot me a private message with your account information

When setting up your account, in the registration process....

Check a box that states you have READ, Understand, and Agree to the TOS, failure to check the box your account is not activated.

 

In case you failed to read or skimmed the TOS....

https://www.att.com/legal/terms.internetAttTermsOfService.html

 

16. Customer Service Support

AT&T provides free basic customer care for Service purchased from AT&T and covered under this Agreement. Although AT&T reserves certain rights related to equipment necessary to receive the Service and will repair or replace damaged equipment as AT&T deems necessary (in each case, as described in, and subject to the terms and conditions (including fees and other charges) set forth in, Section 7 above), AT&T does not provide support for devices that access the Service under this Agreement.

 

Personal observation....

The company made the decision to block port 25, and provides two options using SSL to sent email. If your desire ADVANCED support for special request (unblocking port 25) for your device then ConnecTech is the company policy. Tier 1 support is properly following company guideline by referring to PAID support for a one time charge or $180 annual, billed $15 per month.

 ATTDSLCare, Could you help open my port up? I don't see an option here for private messages. Support does not seem to understand my question.

Hi,

The way I got it open was just to post the question here. This technician
from a higher level then said he had opened the port. It is not something
you can do yourself as a user. It has to be done at the higher support
level. But, as you see, you really can't get to them directly. I agree, it
should be available for user to set themselves. But, it is what it is. You
could email the links here to AT&T and see if you could get someone. Good
luck.
