PLAIN is the default. It is ALWAYS available, even if you have other methods in place. Therefore, your system now just drops down to PLAIN before trying anything else ! Therefore, you will see a speed increase as the system just logs in , rather than trying anything else first. Of course, if the other AUTH methods you advertise work, then they should be similar in speed. What generally happens is that the server will advertise an AUTH method that it doesn't support. Then you see speed loss due to try and catch handshaking while the client drops down each time to a lower level of authentication. This can kill sessions. So its try, stop and wait, try something else, stop and wait, try stop and wait, oh that one works !!

Hi Stan,

Last time, I let those configuration as default:

$rcmail_config['imap_auth_type'] = null; $rcmail_config['imap_root'] = null; $rcmail_config['imap_delimiter'] = null;

Now, my one is:

$rcmail_config['imap_auth_type'] = "plain"; $rcmail_config['imap_root'] = null; $rcmail_config['imap_delimiter'] = "."; //a dot for delimiter

1. $rcmail_config['imap_auth_type'] = "plain";

Actually, in MYSQL database, the Password is MD5-CRYPT. I just checked it again, the password was store like "$1$51dd62a1$RxZRpwoZ/q5EuEH/3epFp". But I don't know why I setup the PLAIN and it's still working. This is my experience when I configure for ManageSieve Plugin (of RoundCube). I also set Plain for ManageSieve and it works.

2. $rcmail_config['imap_root'] = ""; //blank

I store all mails in the directory of each user, so this parameter is blank.

3. $rcmail_config['imap_delimiter'] = ".";

I'm using Dovecot and the Default folder Delimiter is a dot "."

In my opinion, the first one, "imap_auth_type", is the most important parameter to speed up when you are login, and when you're click on other folders in the interface. I changed it once and the effect was very good. It was true in my case. For the second and the third, I see no effect but I still want to change it.
