Connecting to remote SMTP mail server

Sorry

I saw you were off-line and had to get back to them so I mentioned everything stated above.

Hope this does not cause a problem

I think that it is likely they are doing exactly what we discussed here, and probably just are not aware of that option. Ask them what firewall they are using, and if it is CSF explain those options to them that they need to change.

I asked them about their firewall, direct socket connection and all that and they came back to me with one sentence"

"You may get the issue because 25 port is already being listened by mail server. And your socket conflicts"

When I saw this I lost it completely.
I have it in writing that they promised me access to port 25 and I had told them that I used a socket connection, Now after 3 days they tell me there is a conflict when they were trying to make it work for m.

They have an option to forward complainst to their CEO and I went on the live chat and told them I was disgusted with their support to forward my issue to their CEO.

They kept insisting "As I already told you this port is already dedicated to SMTP server"

For which I replied I was told I would have access to port 25 for which they say "you was told that port is opened on firewall".
If a port is opened especially for me on firewall then I should have access to it.

After various threats back and forth, they indicated they would escalate the issue with their admins. Not absolutely sure what this means but it better be possitive.

I really find this hard to believe what I am going through.

What do you think about their comments and my so called conflict

Hi BWM

This is their response:

"We have checked it yet again, and port 25 is indeed opened for both inbound and outbound connections. Additionally, we 've checked the firewall, and it does not interfere with port 25 in any way. Thus, if you are still having the problems, we suggest you review you connection methodology."

I am still trying to get what their firewall is

With the way they respond, I am not sure I would have much faith in them figuring anything out. Secondly you aren't trying to connect to port 25 inbound (you would only do that if you used address 127.0.0.1 and that works fine), you are trying to connect to port 25 outbound which is not on your host's server.



You are not connecting to any daemon that is listening on port 25 on their server, so their comments make absolutely no sense. Why would that stop your script from working? When you are trying to connect to port 25 outbound, that means you are trying to connect to port 25 on someone else's server. I predict their firewall is simply not letting you through to do that.

Curious to what the firewall is when you find out.

You can see now what I have been going through

Based on what I saw for your firewall, I was wondering about the following:

Port 587 outbound works fine.
Tell them to look at the SECTION:SMTP Settings in their firewall.
Since port 587 works then for port 587, they probably have SMTP_BLOCK = "0"

I assume the same holds for port 25 outbound but in this case they probably have SMTP_BLOCK = "1"

I am not sure of the order or if I am saying the above correctly.

The question then is how do they unblock port 25 outbound.
For port 25, would they then simply change to SMTP_BLOCK = "0" or is it a little more complicated than that.

I am assuming that they have CSF like you do.

Any changes or corrections to above or order of sequences would be appreciated.

I strongly believe if I do not tell them exactly what to look for this is never going to be resolved.

If I give them a systematic approach to the issue, then this might have a quicker resolution, hopefully that is.

If they are using CSF, then yes, putting:

SMTP_BLOCK = "1"

to

SMTP_BLOCK = "0"

Would most likely resolve the issue if they are willing to do that for you. They need to make sure they restart CSF after making the changes.

There is only one section like this in the firewall, not multiple for multiple ports. Typically they can change SMTP_BLOCK to being on or off, and then specify one or more ports that gets blocked from it.

Hi BWM

I do not know how they did it, but I now have access to port 25 outbound.

I think all the help you gave me lead to them doing this for me.

I do not know for sure, but they might actually have a CSF firewall, but cannot be sure.

Again, thanks for all your help. I don't think this would have happened without your great input.

No problem, glad I could be of help

Hopefully your host knows their firewall a bit better now too! If they ever respond explaining what they did would be curious if they took the advice I gave, or found something else causing issues.

You deserve a medal BWM, seriously i have been watching this post for weeks now.

Someone get that man a beer.

Thanks Zealous

A beer does sound good right about now!
