Trending @Capgemini; Can we mail files to our personal email?

Yes we can send.. Payslips and some other personal docs if needed.. Put the subject relatively so that it will not block at security side

Put #cgp in subject line and send it to your personal id. Note: send only your stuff (payslips and form 16) not anything related to office documents..

I am not sure if it is allowed but I have been doing it for long time

No, sending files like payslips to your personal email is against company policy. Always follow company guidelines to avoid any compliance issues.
