**(34) How are identities matched?**
Identities are as expected matched by account.
For incoming messages the *to* and *cc* address will be checked and for outgoing messages the *from* addresses will be checked.
For incoming messages the (delivered) *to* and *cc* address will be checked and for outgoing messages the *from* addresses will be checked.
Archived messages will be considered as incoming messages, but additionally the *from* address will be checked.
The matched address will be shown as *via* in the addresses section.
