no problem

3 GB Memory on your VM is a little bit small

having in mind that each connection needs memory for imapd/pop3d and 
per-connection
buffers additional to the OS himself, postfix and the innodb-buffer is really 
important
i can not imagine how i would deal with 3 GB because this hurts if there are 
many
open connections or as in your case something allocates memory too

limit the maximum of imap-connections is often not possible depending on the 
number
of users - this will be much better in dbmail 3.x by using connection-pooling 
but
with 2.x you have for every imap-connection a imapd-process and a db-connection 
with
all its overheads (don't forget mysql-connections from postfix/sasl)

in the 3 years using dbmail now i learned that as much RAM as possible is the 
only
way to get this really fast running
