@afuego no, the panel.ini senderaddress is for notifications only. pmmcli-rc is for backup tacks only. everything else is managed by psa.conf mail settings. however I'm not sure psa.conf frommail works with msmtp

@Giuseppe are you saying you accomplish getting all the notifications from a valid email address [not root (cron deamon)] by adding the following into the Panel.ini

[notification]
senderAddress=<custom email address>

Plesk support doesnt recommend the Postfix relay due can be overwriten by a Plesk update.

@Giuseppe thank you for the information, I'll have to research this situation further. Have great day!

@afuego i use it all the time, i have over an hundred scheduled task. and over 50 servers running on plesk (i run an ISP). all my notifications have my custom email address in the from field. when i say all i mean notifications, pmmcli tasks, psa tasks, and cron. so you can definitely change them, even on msmtp (which anyway is not recommended using for system mails, just configure postfix to relay only them)

@Giuseppe I have been talking with Plesk support for weeks regarding this matter, using Plesk as mail server is not the best scenario.

It seems like you have not used the feature for Scheduled Tasks that's why you are unaware of the problem.

@afuego you can change that, i don't get any email from root. you need to change different conf files.
also using msmtp is not a good way to manage your server. you should always keep a local mailserver working.

@Giuseppe Scheduled Task emails, they come from root (cron deamon)

Plesk does not offer any way to change this.

yes it's already implemented, but senderaddress is for notifications. if you are talking about backup tasks you can set it in another file. and another one for plesk ones.
it's already all customizable, you just need to read the manual to find which one you need to modify.

@Kaspar is not implemented yet.

[notification]
senderAddress=<custom email address>

Does not override Scheduled Tasks emails, they still come FROM email address: root (cron deamon)

Wow...fantastic! Almost sounds too good to be true :-) Thanks!!

This feature has been added to Plesk version 18.0.45. It can be set in the panel.ini file. From the change log:

Plesk administrator can now specify a custom email address to be used as a mail relay (the address will be used as the sender address for all Plesk email notifications found in “Tools & Settings” > “Notifications”). Using an email address with a properly configured domain (DKIM, SPF records, etc.) would ensure that the notifications would not be treated as spam. To do so, add the following lines to the panel.ini file:

[notification]
senderAddress=<custom email address>

@vimobe: This is not related to this topic in any way, neither as a cause, nor as a solution.

My domain and ip blacklisted due to frequent notifications detected as spam/junk

This is annoying

@mike No they don't. They work just fine for me. You need to learn how to configure a mailserver with proper spf\dkim records.

I think its time for doing not consideration. Plesk notifications go to junk folders in outlook/hotmail & gmail. Unacceptable !

Mails sent by the server are @hostname.domain.tld which is ugly and may cause spam rejection in some cases. It's unbelievable that it now has a support page for the lacking feature, while it's been almost 4 years for this uservoice and it's still not implemented. Customizing the "From" or setting up an SMTP relay is basic email functionality that Plesk shouldn't skip on. Since the post of this uservoice, Plesk team should have been working on it.

It would be a much appreciated feature.

Really need this feature.

@Scott What do you mean? Plesk supports TLS, STARTTLS and SSL since ages.
