[Solved] - Owner/Permissions problem: Unable to receive e-mail

[Sattva]

unable to set gid=12 or uid=505 (euid=93): local delivery to name <name()pifagor.org> transport=local_delivery

Приветствую.

$5 Готов пожертвовать за эффективную подсказку.


Взломали старый Wordpress. Отправляли 30 000 писем за сутки.
Сменил права на

Code: Select all

/usr/sbin/sendmail

chmod 0644 /usr/sbin/sendmail

Попытка вернуть права на 755 обратно эффекта не дала.
Вероятно испортил права и владельца.
Подскажите, пожалуйста, какими должны быть права и владелец?

Жалею.

chmod 0755 /usr/sbin/sendmail
После этого почта отправляться перестала по sendmail, но теперь она и получаться перестала.
Отправляется по SMTP, но через RoundCube отправка невозможна - получаю ошибку (сообщение о невозможности отправить почту).

Сейчас в "ручном режиме" пользуюсь этим для доставки почты:

To forcefully send all the mails:
exiqgrep -zi | xargs exim -M

2016-03-01 20:08:57 [18321] cwd=/usr/sbin 3 args: exim -M 1aaivM-0002Qs-OL

Искал весь день по строкам:

Code: Select all

unable to set gid=12 or uid=505
failed to read delivery status for
appendfile transport process returned non-zero status

но так ничего и не нашел толкового, кроме того, что проблема должна быть именно в правах.


Ставил VestaCP в Апреле 2013 и она же настроила Exim + Dovecot + Roundcube.

Нашел

Code: Select all

10-master.conf
---
service auth {
  unix_listener auth-client {
    group = mail
    mode = 0660
    user = dovecot
  }
  user = dovecot

gid=12 Изучаю:
---
id mail
gid=12(mail)

Значит, этой группе что-то должно принадлежать?

Code: Select all

chown dovecot:mail dovecot
Эффекта не дало.
