***************************************
For all server
***************************************

* SSL / TLS / SSL-TLS

* STARTTLS

* Authentification
- LOGIN
- PLAIN
- USER
- CRAM-MD5
- DIGEST-MD5
- NTLM
- KERBEROS (KERBEROS_V4 ?)
- GSSAPI (voir [URL visible pour les membres Pro] au cas où cela peut vous aider)
- ANONYMOUS
- EXTERNAL
- SKEY

* Multihoming (ie you can choose one or more IP addr to listen). ie : NOT this->listen(HostAddress:: Any, int port) butr this->listen("IPV4, IPV6, other IPV4, other IPV6, ...", int port ; connection type = "TLS OR SSL OR NORMAL");

Example :

Hostname|IP PORT SAFETY CERTIFICAT

domaineA.tld|IPV6|IPV4 993 SSL c:\mailServer\cert\domaineA-ssl.cert
domaineA.tld|IPV6|IPV4 995 TLS c:\mailServer\cert\domaineA-ssl.cert
domaineA.tld|IPV6|IPV4 143 NON

-> So an email client can connect to the domain domaineA.tld in "unsafe" or "SSL", "TLS"

domaineB.tld 993 SSL c:\mailServer\cert\domaineB-ssl.cert
domaineB.tld 995 TLS c:\mailServer\cert\domaineB-ssl.cert

-> So an email client can connect to the domain domaineB.tld in secure mode: SSL or TLS

domaineC.tld 143 NON
And an email client can connect to the domain domaineC.tld in unsafe mode

IPV6 (ex : 2001:0:5ef5:79fd:108b:204d:b136:3fb) 993 SSL c:\mailServer\cert\domaineA-ssl.cert
IPV6 (ex : 2001:0:5ef5:79fd:108b:204d:b136:3fb) 995 TLS c:\mailServer\cert\domaineA-ssl.cert

* Support direct connections or by proxy

* Multi domaine
- Check before the connection if the domain and/or account is enabled (not disabled)
- Quota support per domain and account

* Use SqLite or text files to store messages or user credentials (eg login password)

* Detailed logs

* Forbidde access in this server from on or more IPs

* If the client connects but for some time (Do not send data), it automatically disconnects "Connection timeout"
