limit user access to certain IP addresses?

[Michael Menge]

Hi,

I tried this some thime ago with pam, but without a success.

SASL does not pass the ip-addres to PAM so you can't use pam_access,
nor can you change/configure the PAM service name to run an other  
instance of cyrus using an other pam configuration.

You may have success by running too instances of cyrus, one listening  
on 127.0.0.1 and one on your normal IP und using different  
sasl_options in your imapd.conf configurations
