BTW, I'd be interested to hear how you get on with using the mail relay service. If you have the time when you' got it running and a spare moment could you post an update in this thread? If if your issue is resolved could you also mark this thread as ["Solved]" (unfortunately you'll have to edit your first post to modify the title)?
Glad I helped! Yeah so, I created an account on SendGrid via Microsoft Azure and followed the article here https://wiki.zimbra.com/wiki/Outgoing_SMTP_Authentication. I put "smtp.sendgrid.net" as the mailrelay.example.com, my SendGrid username & password where needed and my zmhostname as the <server>. Pretty easy configuration. A mistake I made was that I put the sendgrid server and port on the External domain MTA setting in General Settings (Zimbra Admin url) and so I couldn't send any emails despite my above configuration. But when I deleted that, it all worked.
One question though, how could I set up zimbra to work (and send emails) without having to set up an external smtp relay? I know that Azure blocks smtp connections that use port 25, but doesn't zimbra "work" as an authenticated smtp server? (Can't exactly describe that well, but I hope you get my point)
And as always, thank you very much for you help.
