918df65a3a Require that networks in allowed_nets are networks and not hosts 2021-03-13 20:40:25 -05:00

0503c12ccd Allow "allowed_nets" to be empty, meaning any network is allowed 2021-03-13 20:34:48 -05:00
Jonathon Reinhart
ef3f9c8ea0 Move parsing of "allowed_nets" out to ConfigLoad() 
This has several benefits:
- Configuration errors are caught at startup rather than upon a connection
- connectionChecker() has less work to do for each connection

Jonathon Reinhart
4036213dd5 Simplify peerIP determination in connectionChecker() 
peerIP = net.ParseIP(addr.IP.String())

can be simplified to just:

    peerIP = addr.IP

but we can also skip the safe cast since we know the net.Addr will always
be net.TCPAddr because we only have TCP listeners.

095fba119a Change default logfile to empty string (meaning stderr) 
The causes logrus to write to stderr.

0e8986ca79 Expand allowedUsers email field to support comma-separated and domains (#9) 
* Expand allowedUsers email field to support comma-separated and domains

Closes #8

* Refactor AuthFetch() to return AuthUser struct

Also, this breaks out a parseLine() function which can be easily tested.

* Ignore empty addrs after splitting commas

This ignores a trailing comma

* Add tests for auth parseLine()

* Update documentation in smtprelay.ini

* Fix bug where addrAllowed() was incorrectly case-sensitive

* Update allowedUsers allowed domain format to require leading @

This disambiguates a local user ('john.smith') from a domain ('example.com')
