Settings

What holds for the whole instance, whoever is signed in. Your own name, e-mail and password are under Account.

01

Log retention

The main driver of /data growth. Does not affect mail.log rotation (fourteen daily files).

The inbound log also never holds more than 10 000 rows: refused mail is logged at the rate strangers knock on port 25.

02

Notifications

From postmaster@mail.example.org, to every user who has an e-mail and has not turned them off under Account.

Notifications are sent without it, and a receiver may file them as spam.

Sending rate limits

Time zone

Read-only
Zone
Europe/Moscow
UTC+03:00. Set in .env (TZ); restart to change.

Every time the panel shows, and every day it counts - today on Health, the days of the statistics - is this zone's, and so are the stamps of mail.log. One exception: the day a DMARC report covers is the reporter's, in UTC.
