[LUG] Mail server setup review

 

Sorry for the burst of posts from me today, trying to do a little catchup
and refocusing :)

A few weeks back i was asking about the whole scenario of getting my
server to go and retreive my mail and then serve it up to me locally via
imap.

Well, weekend before last i hurt my back in a way that meant i couldn't do
anything much so i sat there with my laptop on the sofa and implemented
it.

I have:
- postfix as my mta
- fetchmail going off and getting my mail for me (every 5 minutes)
- courier serving it back up locally via imap
- squirrelmail serving it up via web when i'm away

It seems to be working very well incidentally so thank you to the guidance
i was given!

I just want to know if i should be concerned about security at all.
Currently, i have hardware nat on my router (well, software nat i guess -
whatever it is it's on my router, which is also NOT my adsl gateway, it's
on a different ip network to that).

On the router that handles my internal network i have only opened up a
port for squirrelmail, and that port is not 80, it's a port that i chose
randomly so it wouldn't be quite so easy for someone to find.

I've not yet implemented SSL on the squirrelmail login / connection since
i got as far as i could with the time i had before having to work away.

Is there anything i ought to review about this setup?

Should i really be concerned about the lack of SSL to the web port?

Thanks for any comments as always.

Martin.
