    Hi there,

    Can anyone create an "how to" for setting up an secure and save relay server with spam and virus filtering.

    This because my isp blocks port 25.
    But I have the possibility to use a vps server externally with no port restrictions or port blocks.
    I want to use the relay server with both linux and windows servers.

    Can anyone please create an "how to" for this?

    Many thanks in advance!!

    Cheers Chris

    Thanks Falko,

    But I want to install a server that relays for me.
    And it needs to be secure and manageble.

    For example I can't receive e-mail on my home IP address on port 25.
    So I need to re-route to another port like 465, 587 or other.

    I also want it to scan the mail before relaying and/or hold when my home server is down for whatever reason.
    And set when to remove e-mail when retry/holding time is passed.

    So I want it to do more than just relay.
    I want it to:
    1- recieve email for only registerd domains.
    2- scan for spam and virus on e-mails
    3- verify sending server by IP, mac-address or username/password.
    4- relay when possible
    5- hold and retry when not possible (for X time and X retries)
    6- Filter on size. For example:
    domain example.tld can relay 5MB per massage but can do 10MB per message.

    Thanks again.
