IMAP proxy detect MUA?

Server NGINX
1

Hi,

I’m looking for a way to detect particular mail user agents so I can
direct them to particular IMAP servers or even block them. I know
there is a mail user-agent header… can I access it from the Nginx IMAP
proxy configuration? Will Nginx pass it through to the auth_http
backend?

I’m a little reluctant to set up a mail server just to test =)

Regards,
Cliff

Is there? Are you sure you don’t confuse mail message with IMAP
protocol?

You mean X-Mailer is only available for SMTP?

Ah yes, I see that is the case. Well, if anyone has a suggestion for
keeping Thunderbird 3.0 away from your IMAP servers, I’d love to hear it

Cliff,

No, X-Mailer is also not available for SMTP :wink:
It is optional header of mail message (sent via SMTP “DATA” command).
