Hi, I'm familiar with proxy envirnoment variables such as (both lower and upper case versions): use_proxy soap_use_proxy http_proxy https_proxy ftp_proxy rsync_proxy no_proxy all_proxy Thunderbird at least pay attention to some of them, and honestly, before I haven't needed anything else. However, inside the company, I need to setup manually under TB: SOCKS Host: <...> Port: <...> As SOCKS v5. Where the socks host is the same as the other proxy hosts, but its socks port must be different than the rest. I don't use any DE, but I have some automation through bash+xinitrc which depends on how to set the env. vars, so that I only need to set on TB/FF "use system proxy settings". I've tried several possible env. vars (both lower and upper case) like: socks_proxy socks_server socks_version smtp_proxy="socks5://<proxy_host>:<port>" So far I haven't been able to get any possitive results. Does any one know how I might be able to set socks for TB through env. vars? Thanks, -- Javier
