I am assisting my friend Lindsay in aged care to enable him to continue to use Thunderbird for email. Currently TB will receive mail but unable to send.

This is complicated in that Lindsay is paying iPrimus.com.au a monthly fee to enable him to use an old email address xx@bluep.com. I can log in to the iPrimus web portal to send and receive xx@bluep.com emails, https://webmail.iprimus.com.au/?_task=mail&_mbox=INBOX.

I downloaded Thunderbird version 115.6.0 (64-bit) on my pc this morning and the Auto Set Up configured mail.bluep.com as the incoming (POP) and outgoing (SMTO) servers. Mail is coming in but not sending.

I changed the outgoing server to smtp.iprimus.com.au, default port 587 however messages still cannot be sent and Thunderbird shows that smtp settings must be reconfigured.

I spoke this morning to iPrimus Tech Support who advised the default smtp port should be 25, not 587. However I have found that resetting the smtp port to 25 does not enable emails to send.

Note that I have previously set the smtp port to 587 which enabled sending on non ISP connections. This ability would be required as Lindsay is using whatever Wi-Fi service is available in the facility.

iPrimus Tech Support have suggested I should contact Thunderbird (Mozilla) about this problem.

Can you advise Thunderbird server settings for this situation.

Thanks for you assistance. Regards, Peter M

Thunderbird needs the correct settings to send and the settings are setup by iprimus - Thunderbird does not choose whatever settings are required and it is not a server. But I think you are talking about trying to use a method of relay via another server to send.

Generally the iprimus SMTP server settings would be:

  • Outgoing Server SMTP: smtp.iprimus.com.au
  • Port: 25
  • Connection Security: None
  • Authentication Method: Password transmitted insecurely
  • User Name: full email address

Did you previously select 'Authentication Method' to send password insecurely? Or did you select 'No authentication' ? If the latter then try using 'Password transmitted insecurely'.

However, you may find the residential home ISP is blocking port 25 for security reasons. This is the ISP not allowing sent via port 25 as a relay for other servers. It's also common for most public wifi hotspots to block port 25 as well. It's a common practice among ISPs to prevent spam and other email-related security issues and most commonly used by hotels etc.

Usually, you can try the following to see if it gets allowed but I did not find these settings mentioned by iprimus.

  • Outgoing Server SMTP: smtp.iprimus.com.au
  • Port: 587
  • Connection Security: STARTTLS
  • Authentication Method: Normal Password
  • User Name: full email address

In addition make sure the computer Firewall (note if installed Anti-Virus then it may control the Firewall) has Thunderbird program set up as an allowed program.

An alternative you could try would be to create a gmail account and get emails forwarded from iprimus account to the gmail account, then set up gmail account in Thunderbird.
