Unable to send, receive, and login to email. Using Roundcube, ISPConfig, Proxmox.

[djmixx07]

Hi everyone, embarrassingly speaking..I am a complete newbie when it comes to Linux and server administration. I am trapped in a situation in my current work that all was turned over to me when our network administrator resigned. I work at a government office here in the Philippines.

So here goes the problem. Our email (neither Roundcube or Thunderbird) is unable to send and receive emails. I am also unable to login to Roundcube. It just loads for a while after logging in then goes to the next page which is just a plain white page. Upon checking in ISPConfig, all the servers are online, specially POP3 and SMTP.

So I just can't figure out whats going on, and what's wrong with it. It was working perfectly last week. Then just broke down all of a sudden. I did series of shutdowns and restarts at our 2 baremetal servers..but to no avail.
I am not sure if it's about postfix because when I do "/etc/init.d/postfix restart", it says that it's already running.. But when I do "/etc/init.d/postfix status", it says it's not running..which is very confusing as well.

I really hope for your help guys. I would greatly appreciate any assistance. Thanks in advance.

PS:
Since I am a complete novice in Linux, if you can assist also in what command to type in terminal..I would REALLY appreciate it.

Kindly,
DJ

Which distribution do you use? Do you use ISPConfig 2 or 3?

Are there any errors in your mail log?

Hi Falko,

I think we are using ISPConfig 2.x.

Here are what's in my mail log..(quite long but repetitive):

Thanks so much for giving time on my issue.

I did telnet localhost 25, these are the results:

Please try this:

newaliases
/etc/init.d/postfix restart

Hi Falko,

Here are the results from what you asked me to do.

mail:~# newaliases
mail:~# /etc/init.d/postfix restart
Stopping Postfix Mail Transport Agent: postfix.
Starting Postfix Mail Transport Agent: postfixpostfix/postfix-script: fatal: the Postfix mail system is already running
 failed!

and my mail.log now is different (sorry quite long).
