+#+TITLE: Change email password
+#+DATE: <2024-11-02 Sat>
+
+* Preamble
+
+Users' password to access their inbox are stored in
+/etc/mail/passwd. As this file is read-only, we first need to adjust
+permissions before modifying it.
+
+
+* Change file permission
+
+#+begin_quote
+$ doas chgrp wheel /etc/mail/passwd
+$ doas chmod g+w /etc/mail/passwd
+#+end_quote
+
+* Backup the file
+
+#+begin_quote
+$ doas cp /etc/mail/passwd /etc/mail/passwd.2024110201
+#+end_quote
+
+* Generate new password
+
+For that, we use the utility doveadm
+
+#+begin_quote
+$ das doveadm pw -s blf-crypt -u ariciu
+#+end_quote
+
+Replace the old password, in /etc/mail/passwd, by this one, without
+the prefix.
+
