Takeaways:
- SquirrelMail is a free open source Web-based email client tool for Linux systems
that integrates to Postfix and Dovecot local servers.
- SquirrelMail 1.4.23-svn seems to have a bug that prevents "apache" user to access the data directory.
But SquirrelMail 1.4.22 works perfectly.
- You can use regular IMAP and SMTP ports 143 and 25 without TLS encryption
with "localhost" to access mail server running on the same computer as SquirrelMail.
- You should use secure IMAPS and SMTPS ports 993 and 465 with TLS encryption
to access remote mail servers.
- You should install mail server's self-signed certificate as a trusted certificate
for SquirrelMail's PHP environment.
