< h3 id = "additional-greylisting-whitelist-support" > Additional greylisting whitelist support< / h3 >
< p > Seems many companies setup their mail servers to re-deliver returned email
immediately from another server, this causes trouble with greylisting.< / p >
< p > Possible solutions:< / p >
< ol >
< li > Disable greylisting on your server completely.< / li >
< li > Whitelist IP addresses/networks of their mail servers.< / li >
< / ol >
< p > For solution #2, you can whitelist those mail servers with script
< code > /opt/iredapd/tools/spf_to_greylit_whitelists.py< / code > .< / p >
< blockquote >
< p > Note: script < code > tools/spf_to_greylit_whitelists.py< / code > is available in iRedAPD-1.8.0 and later releases.< / p >
< / blockquote >
< p > It queries SPF and MX records of specified mail domain names, then store all
converted IP addresses/networks defined in SPF/MX records in SQL table
< code > iredapd.greylisting_whitelists< / code > .< / p >
< p > To whitelist IP addresses/networks of some mail domain, for example,
< code > outlook.com< / code > , < code > microsoft.com< / code > , please run command like below:< / p >
< pre > < code > # cd /opt/iredapd/tools/
# python spf_to_greylit_whitelists.py outlook.com microsoft.com
< / code > < / pre >
< p > If you want to whitelist more mail domains, just run the command with the
domain names like above sample.< / p >
< p > Since iRedAPD-1.8.0, we have SQL table < code > iredapd.greylisting_whitelist_domains< / code >
to store these mail domain names. if you run < code > spf_to_greylit_whitelists.py< / code >
without any argument, it will fetch all mail domains stored in sql table
< code > greylisting_whitelist_domains< / code > instead of fetching from command line arguments.< / p >
< pre > < code > # python spf_to_greylit_whitelists.py
< / code > < / pre >
< p > You should setup a cron job to run this script, so that it can keep the IP
addresses/networks up to date. iRedMail sets up the cron job to run every 10
minutes, like below:< / p >
