[H-GEN] Filtering/Removal of email headers: Is this normal?

[Brendon Higgins]

Hi list,

I've discovered something funky going on with emails going through my 
university address, and was hoping for some advice from the more 
knowledgeable among you.

I send all my email through my gmail account, but for work related stuff I 
send using my uni identity. So this means in the headers of the email are 
these two lines, a "From:" line with my uni address, and a "Sender:" line 
with my gmail address. Perfectly normal RFC 2822, AFAICT.

I just discovered that emails going through university addresses via the 
webmail/forwarding system have their headers filtered and changed such that 
if there's a "Sender:" address, the "From:" line is deleted and the "Sender:" 
address becomes the new "From:" address. (Oddly, it seems that accounts (such 
as mine) that are set to be redirected, as opposed to forwarded (i.e. sends a 
copy but keeps the message in the webmail box), go through unaffected.)

This has the added bonus of screwing up the "From:" address of university 
mailing lists (the owner of the list is marked as the Sender, which gets put 
into the From address, and so they typically end up getting all the replies 
to any messages sent to the list by mistake).

So what do you think? Is this something misconfigured in the system, as I 
suspect (and which I will soon complain about), or is it actually a normal 
thing to filter/delete like this?

Peace,
Brendon
