gmail rejecting email

[Chris-H]

Using thunderbird I use one of my plusnet email accounts  to send to gmail. All emails from this account to any gmail account is rejected though it was working last week. My other plusnet email works fine as do my other virgin accounts. (They all use the same smtp settings)

  address@gmail.com
    host gmail-smtp-in.l.google.com [142.250.102.26]
    SMTP error from remote mail server after pipelined end of data:
    550-5.7.26 This message does not have authentication information or fails to
    550-5.7.26 pass authentication checks. To best protect our users from spam, the

You will need to take this up with Plusnet as neither they nor Gmail are connected to Virgin Media.

You should not be using the VM SMTP server to send Plusnet emails.  You need to use the relevant Plusnet SMTP server.

My bad, I assumed all outgoing email had to go through the same smtp server.
