Emails not sent due to SPAM claim

[phambley]

When I try to reply to an email the reply is labelled as SPAM and not sent.

The message I receive is similar to the following:

An unknown error has occurred. Subject '___________________ ', Account: 'Home Mail Server', Server: 'mail.tpg.com.au', Protocol: SMTP, Server Response: '554 5.7.1 [TPG-S02] [0BAJwfTx012057] Message rejected as it appears to be spam. Use SMTP AUTH, PostOffice, or contact the Postmaster Team <postmaster@tpg.com.au>', Port: 25, Secure(SSL): No, Server Error: 554, Error Number: 0x800CCC6F

If I go in through the postmaster@tpg.com.au site I can cut and paste the email reply to the mailing site and it appears as though it gets sent.

Can someone, hopefully TPG, fix my mail account.

Cheers

Phil

Hi @RO, 

The most basic step for this issue can be found on this link: Cannot Send Email Rejected by the Server/Banned from using SMTP 

• May we know what type email client you are using? 
• Have you tried uninstalling/reinstaling the mail app?

I am using Microsoft outlook.

I can send some emails to some people and they go through but there are many that give this same error message

The following recipient(s) cannot be reached:

      'name xxxxx' on 27/01/2021 5:23 PM

Sorry I forgot to mention that I have updated and changed my password several times both through my tpg login account and then through outlook so they are all the same. This hasn't worked.

Thanks for providing further details, @RO. 

We've passed them along to our PostMaster. 

Further updates will be provided once available.

Hi @RO! 

PostMaster advises that you will need to enable the SMTP Authentication on your email and try to use port 587. 

Let us know how it goes.
