[resolved] Can't connect to mail.xxxxx.xxx.xx,143: Permission denied

We are using Lotus Notes as our mail server.  I tried to setup an email account in osTicket system.

After I filled in the following information...

Email Login Information section
   Username: abc
   Password: abc
   ...
Fetching Email via IMAP or POP section
   Status: Enable
   Hostname: xxxx.xxxxx.xxx.xx
   Port Number: 143
   Mail box protocol: IMAP
   Fetched Emails: Move to folder: /var/mail/xxxxxx

I pressed the 'Submit' button but it failed to connect to IMAP.

At the top of the screen, it showed "Invalid login.  Check IMAP settings"

In IMAP section, it showed "Can't connect to mail.xxxxx.xxx.xx,143: Permission denied"

When I tested with telnet command, I could login IMAP successfully:

# telnet  mail.xxxxx.xxx.xx 143
Trying 172.5.2.1...
Connected to mail.xxxxx.xxx.xx.
Escape character is '^]'.

What things I miss for connecting to the IMAP?

My osTicket version is v1.9.12.  We are using RedHat Enterprise Linux, v6.6.

Could be a SELinux issue..

What SELinux issue?  I am using RedHat.

If it is linux issue, not Lotus Notes mail server's issue, why can I login the IMAP using telnet command?

samsonahk

I doubt that the login information formatted by osTicket has something wrong.  When the mail server received the login information, the mail server could not get the correct login id and password.  Is there any log files of osTicket that I can check for email issue?

The following command solves my problem:

echo 0 >/selinux/enforce

i.e. disable selinux

samsonahk

Thank you google.  I got that from google.

samsonahk

Permanently disabling selinux by:

vi /etc/selinux/config

#SELINUX=enforcing
SELINUX=disabled

Thank you, mfelber

I would actually recommend that you read about SELinux and create a rule that allows the connection rather than disable it completely, but entirely up to you.   Since this is now resolved I am closing this thread and marking it resolved.
