I can't connect to any port 25 (I've tried yahoo mail server), so I can't send mail from the vps :(

  • Posted October 14, 2012

I have installed sendmail, and while I can receive mails, I’m unable to send. I tried to telnet to port 25 of the destination server, and it fails.

I’m able to do it on other vps I have on another company, so I know the destination server is fine.

this command fails here: $ telnet 25 (it never connects…)

In the other vps, it works correctly: $ telnet 25 Trying… Connected to Escape character is ‘^]’. 220 ESMTP YSmtp service ready

Is blocked? Can I ask to unblock it? is necessary that to have a mail server on the vps.

I’ve checked firewall table in my VPS, and doesn’t see if port 25 is blocked. But, when i tried :

telnet 25


Unable to connect from port 25. I can receive email, but because of unable to connect from port 25, i can’t send email.

Port 25 is blocked by DigitalOcean ? If yes, can i suggest to open/allow port 25 in my VPS ?

I have just followed the above post to set up the postfix service. Do I need to request to unblock port 25 and 587?

Blocking port 25 is pretty lame. It means that I can’t put down a contact email address on my sales web page. Or else it means I have to waste time setting up an email server somewhere else, just to do it again here. I thought DO was for small businesses? Isn’t that the whole point of the service?

Hello. I have opened an account just to have my personal email ( hosted here, while all my clients are hosted in 3-4 other dedicated servers in other providers. <br>Is this block still active?

Hi Christopher, <br> <br>Please open a ticket and you’ll have ports unblocked. <br> <br>Unfortunately because we provide a free trial with just an email and a password a lot of people like to abuse that. <br> <br>After you are registered all new servers are unblocked but we need to do a manual refresh for now on the existing servers. <br> <br>Next week that will be automated, but if you open a ticket now it will be cleared up for you. <br> <br>Thanks

I did. Unfortunately, it didn’t work. Looks like is NOT posible to have a mail server here :( <br>I ask them, and the answer they gave was: <br> <br>“No. <br>We can not allow email delivery by anonymous users at this time.” <br> <br>Posted October 14th, 2012 17:53 <br> <br>So I replied asking them why I’m considered an “anonymous user”, if I’m no longer on the trial period; <br>I did got registered and paid for the service. <br>I thought “maybe they didn’t knew I was registered”. So, I told them “My email is”. That mail is the one I used to register, so they could see I wasn’t anonymous. <br> <br>But got no answer. Actually they closed the ticket. <br>I checked the website, forum, TOS, etc, to see if I could find a reference of “anonymous users”, but I didn’t. <br>So I created another ticket asking whats an “anonymous user” and how could I stop being one. <br> <br>I thought maybe I needed to send them an ID or something. <br>Instead, the answer I got was: <br> <br>Who is “”? <br>Support <br> <br>Posted October 14th, 2012 20:23 <br> <br>So, looks like being registered here is not enough to trust you to have a mail server. And thats understable, with all those spammers out there, but, since they didn’t gave me instrucctions to do something so they can trust me, well, it seems there is no procedure planed for gaining that trust. The plan is just not allowing mail delivering, period. <br> <br>Still think your droplets are nice and all, and I’ll use them for non-serious, not-real-work stuff. <br> <br>but is a bummer there is no way to have a mail server. (and it would be nice if such blocking was mentioned at the time of registering). In the end I solved it by getting a diferent VPS provider. Finding one that allows mail servers is easy (actually, this is the only one I have used that blocks it)

Hi, <br> <br>We do block SMTP and a few other ports for new users until we have a chance to verify them to cut down on the incidence of fraud and abuse. <br> <br>Please open a support ticket and we’ll review your account and get those ports unblocked. <br> <br>Thanks
