MySql: 8.0.34-0ubuntu0.22.04.1
I have followed this guide: Postfix With Courier IMAP Mail Server Installation (unfortunately they do not answer questions).
I had to change the encryption method for the user's password because the one recommended in the tutorial is rejected by MySql server: dbname.encrypt does not exist
Recommended user creation query:
INSERT INTO users (id, name, maildir, crypt) VALUES
('postbox@yourdomain.com', 'postbox_yourdomain_com',
'yourdomain.com/postbox/',
encrypt('loginpwd', CONCAT('$5$', MD5(RAND())))
);
Modified user creation query:
INSERT INTO `users` (`id`, `name`, `maildir`, `crypt`) VALUES
('postbox@domain.com', 'Mr. Postbox',
'domain.com/postbox/',
SHA2('loginpwd', 256));
With the modified query I got the user created but, unfortunately, Courier is not able to understand the password encryption.
In file /etc/courier/imapd, next line is found:
IMAP_CAPABILITY_ORIG="IMAP4rev1 UIDPLUS CHILDREN NAMESPACE THREAD=ORDEREDSUBJECT THREAD=REFERENCES SORT QUOTA AUTH=CRAM-MD5 AUTH=CRAM-SHA1 AUTH=CRAM-SHA256 IDLE"
where I have added the AUTH=CRAM-SHA256 capability, which does not work....
So, I am looking for the correct capability statement to be added to the imapd configuration for Courier so that users can authenticate...
Thanks in advance!!
