Hello there! (i have root access)

Recently I have been running an issue that emails are stuck in the Mail Queue Manager.

I'm getting either `H=aspmx.l.google.com [ IP ] Connection timed out` or ` Spool file for MSG_ID is locked (another process is handling this message)`.
But the messages/emails are never sent.

It happens with any domain ( google, Hotmail, Yahoo, etc).

Most threads I found out are pretty old, and I've already tried many other possible solutions.

By executing " /var/log/exim_mainlog " I'm getting:

Bash: 
/var/log/exim_mainlog: line 1: 2021-02-07: command not found
/var/log/exim_mainlog: line 2: 2021-02-07: command not found
/var/log/exim_mainlog: line 3: syntax error near unexpected token `('
/var/log/exim_mainlog: line 3: `2021-02-07 03:38:36 exim 4.94 daemon started: pid=30268, -q1h, listening for SMTP on port 25 (IPv6 and IPv4) port 587 (IPv6 and IPv4) and for SMTPS on port 465 (IPv6 and IPv4)'
And on a specified message when executing " exigrep $msgid /var/log/exim_mainlog " I'm getting:

Bash: 
2021-02-10 05:47:31 cwd=/var/spool/exim 3 args: /usr/sbin/exim -Mc MSG_ID

Any clue will help a lot!

Check if you can able to connect to the google mail server by the telnet
Try:
Code: 
#telnet aspmx.l.google.com 25

It seems like your hosting provider may be blocking port 25 if you aren't able to send any outbound messages. You'd want to speak with the host to confirm this, and they'd be able to tell you what your options are to work around that.

Just to confirm it's not your server firewall, disable csf and try:

Code: 
csf -x
telnet mx1.cpanel.net 25
After that you can re-enable csf by csf -e

# telnet mx1.cpanel.net 25
Trying 208.74.121.68...
telnet: connect to address 208.74.121.68: Connection timed out
It did the same :( So seems a provider issue.

Thanks, guy for you all your help!

If anyone has any other suggestions let me know.
