# Read an S/MIME encrypted mail

You do not need to do anything to read an S/MIME encrypted mail in XgenPlus webmail. Open it as usual and XgenPlus decrypts it with your key. Mail encrypted to an older certificate stays readable after a reissue, because XgenPlus keeps your earlier keys for decryption. The technical signature and encryption files are hidden from the attachment list.

## How to read an S/MIME encrypted mail

1. Open the encrypted mail from your mail list.
2. Read it as usual. XgenPlus decrypts it automatically.

## When to use it

> Last year a client sent Rekha an encrypted contract. She has since reissued her certificate, yet the old mail still opens normally in XgenPlus.

## Good to know

- To reply securely, keep **Encrypt for recipients** on. XgenPlus asks before sending the reply unencrypted.

## Common questions

**Do I need a passphrase, as with PGP?**

No. S/MIME mail opens without a passphrase in webmail. PGP mail asks for your passphrase.

**Can I read the mail in Outlook too?**

Yes, if you install your certificate there from the .p12 file you export in Settings.
