iRedAPD whatever it does is running and not firewalled.
Logs didn't helped a lot.

I can't send and receive e-mail. Roundcube write the same error message.

Any other ideas?

ZhangHuangbin my server just start deliver e-mails. I don't know what was wrong because I did nothing except several reboots.

If problem occurs again I will post.

Anyway thanks for your quick reply.

You can simply remove iRedAPD from postfix config file "main.cf" as a temporary solution:
Remove check_policy_service inet:127.0.0.1:7777 in smtp_recipient_restrictions.

Some questions:

- Is this a busy server? So that i can try to reproduce this issue.
- Any MySQL related error log in log files under /var/log/? such as some component complains "too many connections to mysql server", etc.

Will dive into this issue later.

Hi, @jayt.

Can you help check whether or not you have python module "DBUtils" installed with below command?

# python -c "import DBUtils; print DBUtils.__version__"
1.0

If you don't have it installed, please try to install it with below command:

# easy_install DBUtils

About DBUtils module:

Note: Personally, i hope you can install DBUtils after you got iRedAPD stopped again, so that we can know why it happened, we should find the root cause.

Solved!

This post is essentially a +1. Email broke spontaneously, causing iredapd.log to report 'DUNNO' for local recipient addresses, and mail.info to report 'warning: connect to 127.0.0.1:10031: Connection refused'.

I hadn't run an update on iredadmin in a while. Steps to solution were:

1) Download iRedMail update, `bash tools/upgrade_iredadmin.sh`
2) Converted entries in `/etc/postfix/main.cf` from `127.0.0.1:10031` to `127.0.0.1:7777`
3) `apt-get install python-setuptools && easy_install DButils`
4) `service postfix reload`

Thanks to ZhangHuangbin.
