Я разобрался.
// use this host for sending mails.
// to use SSL connection, set ssl://smtp.host.com
// if left blank, the PHP mail() function is used
// Use %h variable as replacement for user's IMAP hostname
$rcmail_config['smtp_server'] = ' ';
- need use php mail function for sending email without SSL.
php.ini settings:
[mail function]
; For Win32 only.
SMTP = mail.lamer.local
smtp_port = 25
ИМХО полный бред.
