Dear all:

I have a really strange issue, that is when I login my mail server from webmail client (I used SquirrelMail, by the way, I have modified squirrelmail's timeout value, that means not since squirrelmail timeout), I will got timeout issue when I login about 5PM ~ 10PM everyday (it works fine on other time, I also check my cron, that looks no problem), and during this time, I also cannot connect my 993 port with openssl like this:

openssl s_client -connect myDomainName:993

But when I use mail client (such as outlook) to access dovecot, that works fine, and during 5PM ~ 10PM, my web site also works fine, and once I restart computer if I can not login during 5PM ~ 10PM from webmail client. that will work fine.

can you try to help me? below is my configure of dovecot.

*dovecot -n # 1.0.7: /etc/dovecot.conf log_path: /var/run/dovecot/maillog info_log_path: /var/run/dovecot/maillog protocols: imaps ssl_parameters_regenerate: 0 verbose_ssl: yes login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login mail_location: maildir:~/Maildir mail_debug: yes auth default: mechanisms: plain login passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix plugin: convert_mail: mbox:~/Mail:INBOX=/var/mail/%u*
