Hi,
I need some advice off people who know about SRS!
I'm designing a complete mail solution system based largely on open-source
products with custom tweaks, to support SPF, SRS and other validation
schemes (such as DomainKeys) out-of-the-box.
However, I'm having a little trouble under-standing the reasoning for
requiring SRS.
As an example:
My company's domain is mailnetwork.co.uk, which has an SPF record,
authorising the machines exchange.mailnetwork.co.uk (88.208.192.113,
88.208.192.114) and dns.mailnetwork.co.uk (84.18.200.160) to send mail from
mailnetwork.co.uk, and to fail any other servers that attempt to do so.
Now, how does SRS come in to this?
All my current users use one of our registered domains (mailnetwork.co.uk
and andycc.net are currently the two most-used) as their sender addresses -
they are allowed incoming aliases (e.g. andy@mailnetwork.co.uk is an alias
for andy@andycc.net) - however, if a user tries to use an alias as the
sender address it is rewritten to the alias' destination address - e.g. if I
tried to send using a From: address of andy@mailnetwork.co.uk, the mail
server will rewrite it as andy@andycc.net.
When it gets off the ground, users will have the ability to add their own
domains to the system - I'm guessing in this case, the system will act as a
forwarder, and I'm thinking this is where SRS comes in, but I'm a tad
confused how SPF breaks forwarding and the like!!
Any advice/explanations would be appreciated!
Thanks,
Andy
