Richard Zowalla commented on GERONIMO-6793:
-------------------------------------------
Provider scanning is maybe an enhancement / follow-up.
We would need to gather a list of prominent mail providers first (Gmail, Yahoo,
Outlook, AOL, Zoho, Mail.com, ProtonMail, ...) - there might be others around.
Scanning the ciphers itself can be done in bulk via testssl.sh (for example) ,
which can store JSON and subsequently parsed to get an aggegated cipher list.
Possible problem would be, that the ciphers are subject to change - so we would
need to monitor them reliably (if they are hard-coded)

> Key: GERONIMO-6793
> URL: https://issues.apache.org/jira/browse/GERONIMO-6793
> Project: Geronimo
> Issue Type: Improvement
> Security Level: public(Regular issues)
> Components: mail
> Reporter: Richard Zowalla
> Priority: Major
>
> Check and discuss, if it is a good idea to enable all cyphers in TLS/SSL
> protocol handling in MailConnection.java
> Some cyphers are deprecated for good reasons and shouldn't be used.
> This enhancement might possibily include
> * Allow users to specifiy cyphers via properties (custom factory is already
> possible)
> * If we have no user defined cyphers available, fallback to the JVMs default
> cyphers.
>
> This is a follow up issue raised from the discussion on the dev mailing list,
