When the Check for Recipient in LDAP server option is enabled and the rcpt to: field contains an alias or secondary address for an Active Directory user, the following error appears:
rcpt to:alias-email@sampledomain.com 550 recipient <alias-email@sampledomain.com> was not found in LDAP server
To resolve the issue, enable IMSS to check for multiple email addresses or aliases of an Active Directory user.
For IMSS 7.1 Linux and IMSS 7.5 Windows:
- On the IMSS web console, go to Administration > End-User Quarantine.
- Click the User Quarantine Access tab.
- Select the Allow end users to retrieve quarantined email messages with alias email addresses option.
For the other IMSS versions:
Run the following commands on the IMSS Central Controller:
C:\>"osql.exe -U sa -P sa -d imss"
1>"update tb_global_setting set value='proxyAddresses' where name='mail_attr'"
2>"go"
(1 row affected)
1>"quit"
If you are not using the default password for the IMSS database, provide the correct password after "-P".
