This may be due to the recent updates to DS.NLM, which can cause it to hog
service sockets (or something like that).  Anyway, the latest DS.NLM v6.09
(released after NW4SP7A) apparently fixes this problem, but you might want
to read below for another workaround/fix.

Yes!  Especially if you have a large NDS tree and/or lots of synonyms
defined.
I recommend you do the following:

1) Continue to maintain the LDAP synonyms for WinPMail so that WinPMail will
correctly define the outgoing From e-mail address from the LDAP synonym for
each user.
2) Configure Mercury to NOT use LDAP synonyms.  e.g. ldap_synonyms: 0
3) For each LDAP synonym you have defined in NDS, create a corresponding
Mercury alias entry that redirects that synonym to the appropriate user.
Compile the Mercury alias source file into an ALIAS.MER file.

This requires double entry (maintaining both LDAP synonyms and Mercury
aliases), but results in much quicker response time by Mercury since it
doesn't have to search the whole NDS tree looking for a matching synonym for
each e-mail address on each mail message that the Mercury core module
processes.
