Hello. I am using built-in mail server on Sophos XG18 to send weekly backup emails to myself. While testing backup email, I received following errors and was not able to get backups on my email:
SMTP error from remote mail server after RCPT TO:<[REDACTED]>:
504 5.5.2 <Sophos>: Helo command rejected: need fully-qualified hostname
Is there a way to change the name from Sophos
to something that looks like FQDN (e.g. Sophos.fw)?
