-and the mail does NOT go through to the recipient.
The profile being used for sending emails from the sql server is identically setup as the Veeam. Same from- and to-adress. Same server. Same port etc.
XG is MTA and as you can see from the Veeam part of the log the "domain.com" has a SMTP Policy and setup as "Route by MX"
(Edit: The log states that its port 25 being used, but in both Veeam and MSSQL the port 587 and SSL are configured, so not sure whats up with that - probably not important since the Veeam notification is working just fine..)
Any ideas?
