in my example this is MSMTP at 64-180, which uses 68-4 as remote MTA
there's only one difference in my msmtprc:
as a future investigations steps i'd recommend to ask sendgrid's support about MTA logs on their side from your IP address.
what sender, hostname and IP they receive in fact and what's wrong with sender's domain verification.
for now, there's nothing wrong at Plesk side from my point of view. it should work but didn't..
- Return-Path: [email protected] - Plesk server cron root user
- X-Original-To: [email protected] - mailbox, to what finally msg from cron was delivered (adm@ is an alias of this mailuser)
- Delivered-To: [email protected] - Administrator email of my Plesk server
pointed that something is wrong with sender, looks like some misconfiguration there..smtpstatus=550 smtpmsg='550 The from address does not match a verified Sender Identity
