When you open your email end user, your email will get in the inbox, whereas when you try to send a message, an error notice pop up. Here are the actions to do in order to solve this in Outlook, Thunderbird, etc. For GreenNet users, each parameter is listed.
Since the ISP may restrict outbound ports to prevent their connections from using it to send spam, this is especially likely to happen when moving and accessing through a new ISP than usual.
Depending on the specific model of the email software you are using, the steps for switching the port (and which port to use) can differ, but the information provided below covers the majority of the common ones. Invalid recipient addresses are another reason a message cannot be sent; regardless of how confusing the error message seems on the screen, it is typically worthwhile to note it down.
You can go through the information below and fix your Gmail not sending emails.
Thunderbird will often attempt to send for roughly 20 seconds before failing.“Sending of message failed. The message could not be sent because the connection to SMTP server smtp.gn.apc.org timed out.”
- On Account Settings, click (go to the Tools menu).
- Outgoing server (SMTP)” should be located in the middle of the list of accounts on the left side. Press that.
- You will notice one or more outgoing servers in the above right corner of the Account settings dialogue box. The default, which can include “smtp.gn.apc.org,” is generally what you want. To edit, click that.
- gn.apc.org should be the server’s name. You may not be sending over GreenNet if the server name does not finish with gn.apc.org or greennet.org.uk. You can either verify with the services you are using there or switch to GreenNet if this is the case. Ensure that “Use name and password” is checked; the username is typically the part of your email address that comes before the @ symbol or the login name you use to log into GreenNet Webmail. Thunderbird can prompt you for the GreenNet credentials the first time you send something.
- While you’re trying to get it to function, change the port number from “25” to “2525,” and for “connection security,” try “none”. Send another message after clicking “OK.”
- You can try port 587, which demands STARTTLS security, if that doesn’t work. In reality, for security reasons, this is the best choice.
Outlook Express and Windows Mail
- Go to (Tools > Accounts) to access account settings.
- Select “Mail” from the tabs.
- Click “Properties” after selecting your GreenNet email address.
- Verify that you are utilising GreenNet’s SMTP server under the “Servers” tab. And, “smtp.gn.apc.org” should appear in outgoing mail (SMTP).
- Verify that “My server requires authentication” is examined, and the “Settings” should read “same settings as incoming.”
- Once there, adjust the Outgoing Mail Server Port from 25 to 2525 (or opposite, rely on which one is already there) by clicking on the Advanced tab. Attempt 465 with encryption as well.
- Retry sending an email after saving your modifications.
Older versions of Outlook 2003 won’t support port 587 and instead utilise port 465 for secure connections. As a result, we’ll start with port 465 and then switch to port 2525 if necessary.
- Select Tools > Email Accounts.
- Click “Next” after selecting “View or modify existing e-mail accounts.”
- Choose the “Change” button after choosing the appropriate GreenNet email address.
- If that was a GreenNet account, make sure the “Outgoing mail server (SMTP)” box says “smtp.gn.apc.org”. (If you now use “smtp.greennet.org.uk,” it might be wise to switch to “smtp.gn.apc.org”).
- In the bottom right corner, select “More settings”.
- Ensure “My outgoing server (SMTP) requires authentication” is examined by selecting the second tab along, “Outgoing server.” “Use same settings as my incoming mail server” should be selected. You shouldn’t check the box next to “Require secure password authentication.”
- Select “Advanced” from the right-hand menu.
- If you have “25” for “Outgoing server (SMTP),” remove it and try typing 465 instead. Take a look in the box that shows “This server requires a secure connection (SSL)” if it is present. (If your inquiry is concerning an “encrypted” connection and you have the option of selecting “TLS,” do so and select port 587 as described above).
- Select “OK,” “Next,” and “Finish.”
- Send any messages that have already been sent again.
- Use “2525” “Outgoing server (SMTP)” without encryption if you continue to receive errors (not secure).
