Hi
There are two issues here,  Postfix is a MTA, sending messages between mail 
servers, From what I've heard Exim is a good alternative,scaling well, and 
with load controlling configuration parameters. Downloading email from  the 
mail server to the MUA on the user workstation  will likely be using the POP 
or IMAP protocols. If each mail message is large, maybe caused by large 
attachments, or the network infrastructure being slow.
Without details of the 
sort I've mentioned, I don't think you can accurately comment on your 
council's plans. If they have postfix, then they have some FOSS in place, and 
maybe this proposal is an attempt to kill it off.
