the problem is that XOOPS stores the password as an MD5 hash value, meaning an encrypted value. When it checks a password (when you login), it doesn't decrypt the stored password (as MD5 has no decryption), but it encrypts the entered password, and checks that to the encrypted password in the database. If they're the same, it's ok.
I don't know how SQmail handles passwords, but if it just stores it in the db, then it can't be checked with the XOOPS password, as they are not stored in the same way.
Also, contact wjue about this, as I believe it's his module?
