Test Outbound Port Error - SMTP Protocol Configuration & Diagnostics - Relays, Issues Sending & Receiving Mail

Post by BuckyJunior » 2020-03-29 03:05

Hi,

Upon configuring my installation of hMailServer and linking/logging into my defined accounts in hMailServer on Thunderbird, I am unable to receive or send mail.

In hMailServer's documentation, it is recommended to use an ISP's mail server relay in the event that port 25 is blocked. There is a problem with this, though. Due to being a Comcast customer using a residential plan, as well as Comcast's policies in regards to their mail relay, all activities on port 25 are blocked. This means that I cannot use the ISP's relay as referred to in hMailServer's documentation.

To my understanding, hMailServer requires the SMTP relay server to connect on port 25. Is this correct? When running diagnostics without a relay, 'Test outbound port' fails.

I attempted to use a relay on port 587, but this did not correct the issue in regards to sending and receiving mail. Diagnostics shows 'Test outbound port' was successful when using port 587, but with these settings I continue to have trouble receiving or sending mail.

Are there any other relays that support the connection of port 25?

Any suggestions on working around the problem of port 25 being blocked?


Thanks! :D

Nope

That just affects the diagnostics

Create an SMTP relayer and set your comcast details including port587, test by sending a message
Just 'cause I link to a page and say little else doesn't mean I am not being nice.

Hi mattg,

Thank you for the quick reply.

As you suggested, I configured hMailServer to use Comcast through port 587.

I'm still having a bit of trouble.

When looking at the console, it appears outgoing mail reaches the SMTP server, but then dies on its way to its destination.

Your relay is greylisted...can't you authenticate to smtp.comcast.net? I think this will help bypassing greylisting by comcast

Under 'Remote host name' I've got 'smtp.comcast.net' configured on port 587. 'Server requires authentication' is checked and I have input my username and password. SSL/TLS is enabled.

I'm not sure why I would be greylisted if I am connecting through Comcast's relay with authentication.

Change Connection Security to STARTTLS (Optional). Enable Application, SMTP, TCP/IP and DEBUG logging. Disable all other logging. Re-run your test. Post another log excerpt.

That did the trick in regards to sending mail. Thank you for the suggestion!

I am having trouble receiving mail, though. I tested sending an email from my Gmail account to my hMailServer email address, but I did not receive it. Gmail gave me this error:

Code: Select all

The recipient server did not accept our requests to connect: timed out

Just 'cause I link to a page and say little else doesn't mean I am not being nice.

I went through the list and checked intoDNS.com. intoDNS lists all as successful, including MX records.

All ports are forwarded on my router.

IP Ranges are set to default.

I'd call Comcast and ask whether or not they're blocking inbound mail, but due to COVID-19, Comcast support is unavailable.

Ask someone you trust to telnet to your public IP on port 25. If they don't see "220" and your Welcome message in the telnet client, your ISP is firewalling port 25.

If your ISP is blocking port 25, you'll need to use a mail relay service to accept mail for you on port 25 and relay it to you on an alternate port.

Comcast is, in fact, blocking both upstream and downstream connections on port 25, so that would make sense as to why I can send mail through port 587, but not receive on port 25.

Telnets failed.

This is unfortunate.

Does anyone have a suggestion as to what incoming relay/service to use?

Start your search at your current domain registrar. You may already be paying for it.
