Yes, e.g.:

$ ps axu |grep exim
guasch   11891  0.0  0.2  1276  416 pts/5    S    22:00   0:00 grep exim

(no exim running)

$ ifconfig 
lo        Link encap:Local Loopback
[...]

(no net connection. If you are connected to the net, it will be sent
directly to the recipient)

$ echo hi | mail some@email.address.com

$ sudo mailq
 0m   318 18xZYw-0003Du-00 <some@email.address.com>
          some@email.address.com


Now, it will stay there, until the exim goes through the queue
and delivers it.

We have to wait 15 minutes, because in the default exim configuration
messages failed less than 15 minutes ago are not processed.

$ sudo mailq
15m   318 18xZYw-0003Du-00 <some@email.address.com>
          some@email.address.com


$ sudo ifup eth0

(get up the network)

$ sudo /etc/init.d/exim start
Starting MTA: exim.

(start exim)

$ sudo mailq

There is no message in the queue. 

Best regards,

Jaume
