## Notes
- Sophos SG Cluster
- Many VLANs -> Open port 25, 465, 587 for all networks to the mail server
- Which domain? @ga.tum.de probably. just mx record needed in local network
- DNS Server. Hopefully, the Sophos can do it
- For outgoing mails use the mail-gw which relays the mails to the LRZ mailservers which relays it further
- LRZ only accepts mails from a @<...>.tum.de domain, which should be given
- I could use mailcow, without all spam, netfilter and ipv6 stuff (though I love ipv6 and would activate it everywhere)
- Single mailbox needed. (mailcow provideds more)
- imap will be needed for accessing the mails
- though this mail server will be more a imap server than a smtp server
- imap for receiving all the alerts; smtp for relaying of some mails which should go outside the local network
- Do I really need SSL/TLS certs?
- DOMAIN: ga.tum.de
