In my server, I set it to error lever. The location of the error log file. The main difference between the two is: MyISAM offers table-level locking, meaning that when data is being written into a table, the whole table is locked, and if there are other writes that must be performed at the same time on the same table, they will have to wait until the first one has finished writing data.
No, I will not fix your computer Secure mail server Stopping hackers, phishers, spammers, your boss and your neighbour from accessing your server or the traffic in between is important, and easily done.
Authentication Normal email traffic between clients and servers is in open plain text. That includes passwords and content of emails. The rest of the emails are however in clear plain text. SASL can be a royal pain to set up, especially as it does not support storing encrypted passwords by default in Ubuntu.
Therefore my previous editions described how to configure SASL using plain text passwords in the database. Obviously this is not ideal, so there are ways to combine SASL and storing encrypted passwords.
However if you have a more lenient access policy which is wise if you have many users, then you may want SASL in Courier as well: And is very recommended. There are different types of communication to encrypt: The data traffic between your email applications and the server when you read emails or when you send emails, and communication between other email servers and your server.
For the encryption of reading emails, it is Courier you need to configure. For sending, and beetwen server encryption it is Postfix.
TLS in Postfix To encrypt you need certificates. Ubuntu creates some for you for which you can use while setting up the server. However before you go live, it is recommended to create your own with your proper domain name etc.
Please refer to previous edition for more detail. I moved these to the end, for clarity, but that is up to you. But I prefer to enable submission portso that clients can use it, and I can restrict them to TLS only. Also enabled smtps service portfor some compatibility with some older clients outlook express etc.
As this means not all valid emails sent by others can reach your server. However enabling the option to encrypt is a good idea. Be aware that the emails are not encrypted on your machine, nor on the server. For this type of client encryption, please refer to previous edition for more on GnuPG.
Those situations are in combinations of storing encrypted passwords, using MD5 authentication over encrypted traffic. HTTPS You probably also want to insist on https connections over tls if you below add webmail that is exposed to the public.
Securing a web server is out of scope for this howto, but will not be a lot different than the mail server tls settings.
You know have an advanced secure mail server. Now is another good point to test the setup so far and to insert some data in the db.
Webmail Enable web access You may need to enable web access in the firewall. Check the firewall configuration if this necessary. SquirrelMail This howto in previous editions used to have SquirrelMail as the webmail client. It is more mature with a longer testing record. It has a large library of various plugins.By default, Ubuntu doesn’t enable the rewrite engine module after installing Apache.
