How should I configure an account as "no reply"?

How should I configure an account as "no reply"?
Is there any recommendation in this regard?

Thanks

[mdecimus]

Currently this is only possible by creating a Sieve script.

[ghevge]

Do you have an example for this? And some steps on how I can configure it ? Thanks

I solved a similar task using a sieve script.
It should something look like this

# Declare the extensions used by this script.
require ["envelope"];

# Messages to be discarded
if envelope :is "to" ["a-noreply-address@#myfirstdomain#", "another-noreply-address@#myseconddomain"]
{
   discard;
}
else
{
     keep;
}

The script may be scheduled to be run in RCPT-TO stage (Settings-->SMTP->Incoming->RCPT Stage).

PS: use at own risk, I'm still a beginner using sieve script

[ghevge]

@infrequently in the UI console under /settings/smtp-in-rcpt/edit I can only see the "Run Script" which is accepting a sieve script, but it doesn't like the example you provided.

It shows the error: Invalid variable or function name "require"

[mdecimus]

@ghevge you need to add the script to the Sieve page and then reference it from /settings/smtp-in-rcpt/edit

[ghevge]

I've defined the sieve stript in the Sieve-> scripts page with id "noreply". Now how am is supposed to reference it from /settings/smtp-in-rcpt/edit? cause if I just add that script id in the "Run Script", it doesn't work. The page shows the error: Invalid variable or function name "noreply"

[infrequently]

Please enclose the value with qoutes (') to refer to the script in "Run Script".
You may compare with the "DATA stage". My instance of stalwart-mail has script references there by default. But I'm not sure if this depends on the version and/or the upgrade path.

[ghevge]

I've added the 'noreply' in the Run Script field of the Inbound -> RCPT TO Stage, run some tests, but I am still seeing the emails reaching the no-reply account:

My sieve script:

require ["envelope"];

if envelope :is "to" "[email protected]"
{
   discard;
}
else
{
     keep;
}

I've also tried with a version created by chatgpt but still no luck...

[infrequently]

Sorry, I don't know the reason the script doesn't work.
I tested it with the same result.

PS: I don't get the same warnings you posted.

[ghevge]

The only sieve related logs I can see in the mail server logs are :
2024-08-07T14:41:03Z WARN Sieve runtime error (sieve.runtime-error) listenerId = "smtp", protocol = smtp, remoteIp = 209.85.208.41, remotePort = 46271, id = "spam-trap", details = Unknown store, details = Sieve runtime error

could these be the reason why my no reply script is not working ? Or is something else?

[winston0410]

I encountered this as well, have you found out what caused this?

[mdecimus]

@winston0410 you can ignore that, it is actually a warning, not an error. It means that there are no entries in the spam-trap table.

[ghevge]

@mdecimus do you have any idea what am I doing wrong here?

[mdecimus]

@ghevge Take a look at this example, you need to use the reject command instead.

[Aurnytoraink]

For people looking for an easy solution, here is my script :

require ["envelope", "reject"];

if envelope :is "to" "[email protected]" {
    reject "403 You can't reply to this address";
}

The script is then called on the receipt (RCPT) step:
