The mailserver installed on your TheGigabit VPS is called
Exim.
While the mailserver generally requires little interaction for those
sending or receiving average volumes of email, there may be times when
you wish to manage Exim’s settings.
To do so, first log in to your server in a terminal client using
secure shell (SSH). Use the following commands to work with Exim.
Display the number of email messages in the queue
exim -bpc
Display information about email messages in the queue
exim -bp
Displays time queued, size, message-id, sender and recipient.
Display a summary of messages in the queue
exim -bp | exiqsumm
Displays count, volume, oldest, newest, domain, and totals.
Display Exim’s current activity
exiwhat
Test Exim SMTP transaction
exim -bh ipaddress
Spoofs an SMTP transaction, emanating from
ipaddress. Exim’s status will be displayed as the transaction runs. Note that the message will not be delivered.
