Fixed: Invalid Characters in the RCPT TO Command Causing Work Queue Processing Errors and Alerts
AsyncOS 4.5.0-P2 fixes an issue for systems configured to use LDAP acceptance queries. Prior to this release, specifying the characters "<\>" as the RCPT TO prompt in the SMTP conversation (for the envelope recipient) could result in multiple, repeated LDAP queries. This, in turn, could cause the work queue to back up which would result in work queue alerts being generated. This issue has been addressed in this release. [Defect ID: 18978]
