IpSwitch IMail Server version up to 8.1 uses weak encryption algorithm to encrypt its user passwords. Have a look at attached proof of concept tool, which will decrypt user password from local machine instantly.

Unfortunately being able to decrypt passwords is absolutely required in order to support APOP, or SMTP CRAM-MD5 authentication.

With that in mind, this isn't so much a bug, but rather a design flaw necessitated to support the protocols involved.
