День добрый!
Моя задача обновить Slackware 12.0 -> 14.0 c exim4.69 courier mysql
Сейчас Slackware 14.0 exim4.69 courier-imap 4.6.0 mysql 5.5.27 ранее на старом работающем mysql 5.1
использую старую БД exim, переносил как дампом так и файлами..
my.cnf пробовал как старый так и сконфигурированный новый.
Exim не может соединится с Mysql, вот лог файлы:

Может быть причина в не совместимости exim4.69 c mysql 5.5.27?
Спасибо.

Решение:
Проверка соединения
mysql -h 127.0.0.1 -P 3306 -u exim -p
Закончилось ошибкой.
Создал пользователя в mysql:
CREATE USER 'exim'@'%' IDENTIFIED BY 'pass';
GRANT SELECT,INSERT,UPDATE,DELETE,CREATE,DROP ON exim.* TO 'exim'@'%';
Изменил exim.conf строку:
с hide mysql_servers = localhost/exim...
на hide mysql_servers = 127.0.0.1/exim...
Хотя пользователь exim c localhost имелся.
Ну и заработало, всем спасибо, бог в помощь, а без мозгов ни куда...
