I guess you simply have clients which don't care about the offered ID  
extension.

A recent Thunderbird should make you happy :-)

Thank you very much!

Re: Mail User Agent?

2016-02-02 Thread Joseph Tam 

azu...@pobox.sk and Tom Sommer asks:


How this ID extension can be enabled in Dovecot? From which version is
it supported?


Accordind to Dovecot CAPA's response, it is already enabled

* OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE 
IDLE STARTTLS LOGINDISABLED] Ready.

However, as a previous poster noted, Dovecot doesn't do anything with
it other than to log it.  The client can elect to ignore it or send an
ID string.  The ID extension is documented here

https://www.ietf.org/rfc/rfc2971.txt

I speculated it could be used as a client-side CAPA info so that an IMAP
server can modify it's behaviour knowing it's dealing with a certain
client, but that is flatly forbidden by RFC

(Quoting from RFC)
The sole purpose of the ID extension is to enable clients and
servers to exchange information on their implementations for
the purposes of statistical analysis and problem determination.

...

Implementations MUST NOT make operational changes based on the
data sent as part of the ID command or response.  The ID command
is for human consumption only, and is not to be used in improving
the performance of clients or servers.

Thank you for info. Well, i understand that clients are not forced to  
send the info but, in my logs, there's no single ID info. Do i need to  
enable logging of it or something?

Unless I missed some recent changes, neither POP nor IMAP protocols
make provisions for having the client to send such info. As a  
result, dovecot does not have that info.


I regularly get such info in my logs e.g.

	Feb  1 14:10:45 server dovecot: imap(user): ID sent: name=iPhone  
Mail, version=12F70,

os=iOS, os-version=8.3 (12F70)

Only for IMAP (ID extension?).

How do you enable this? I can't seem to find any information about it.
