Problem sending email to a specific domain.

Hello,

We currently have a problem with sending mail with one of our customer. Address mail is name@gmx.******xx.com, we have a notice of non-distribution.
failed to connect to smtp gmx.******xx.com because remote system no longer responding.
Is it possible that sophos blocks sending ?

we have an UTM 9 firmware : 9.104-17

Thanks for your help

Cordialement

  • Salut, wrkobj !

    I suspect that you meant to say 9.106-17,  If not, then you should Up2Date to that version.

    Please show the lines in the SMTP log that include those for the unsent email.

    Cheers - Bob
