Apologies, found that the "remove spaces from host" fixed the problem immediately. Thank you search facility, promise I used you before finding the existing solution!

Hello All,

Happy New Year.

I've come across a little error, it's may not be a TrueNAS's problem but it appears my emails notifications are not getting through.

I use IONOS for the email account sending emails.

A (free) Google account receives them.

Here's an extract of the mail delivery error message found within the IONOS mail inbox (X's have replaced any data considered dicey to make public):

SMTP error from remote server for TEXT command, host: gmail-smtp-in.l.google.com (XXX.XXX.XXX.XXX) reason: 550-5.7.1 [212.227.126.187] Messages missing a valid messageId header are not 550 5.7.1 accepted. XXXXXXXXXXXXXXXXXXXXXXXXXXXX.233 - gsmtp

if anyone else has experienced this and resolved it, I would be very grateful to know.

Many thanks,
Chris
