SYMPTOMS
Importing large numbers of Message Handling Service (MHS) addresses is excessively slow.
CAUSE
A regular MHS address has the form mailbox@node. An extended MHS address has the form placeholder@node{real address}. By default, the DXA parses against the placeholder@node portion of the transaction record and attempts to create a unique alias and proxies using this data.
Using the following example import file, you can see where the slowdown occurs.
AUser AMHS:ServerA@Company{ccmail:usera}
AUser BMHS:ServerA@Company{ccmail:userb}
AUser CMHS:ServerA@Company{ccmail:userc}
AUser DMHS:ServerA@Company{ccmail:userd}
...
AUser AAAMHS:ServerA@Company{ccmail:useraaa}
WORKAROUND
A hotfix is now available that provides a registry setting to tell the Directory Synchronization service (DXA) to use the extended portion of an MHS address for alias and proxy name generation.
NOTE: This hotfix will only parse SMTP and ccMAIL type addresses from the extended address. From an SMTP address it will take the xxx out of an xxx@yyy.com type address and from a ccMAIL address it will take the xxx out of a CCMAIL:xxx type address.
STATUS
