If you use an Iphone (and your mobile proivder supports it) then you are using it ;-)

just my 2 cents

Android apparently supports it as well.

Hi Team,

I need to develop Visual VoiceMail solution. In this solution I need a IMAP4 server, from which I can get a hit for each mail retrieval. Can anyone help me if dovecot can be used for this purpose.

     That is rather vague. Do you want to do something like ol' biff or what we used to do with Asterix 10 years ago (get an email with the voicemail as as attachment)? I guess he is talking about that: https://www.gsma.com/newsroom/wp-content/uploads/2012/07/OMTP_VVM_Specificat...

I skimmed through this. It adds quite a few strange custom bits to the IMAP protocol. Part of this are a few new commands and METADATA items, which should be quite easy to implement. However, the amendments also include various attachment-based QUOTA limits. Dovecot doesn't support this and adding that is not trivial.

Also, this specification is quite old and outdated (it even mentions an MD5 authentication mechanism). Is this even actively used anywhere?

Regards,

Stephan.
