Hi Alick,     Open the ecc_server.ini file for editing in an appropriate plain-text editor. This file is located in the following directory on the ControlCenter server:  \ECC\ecc_inf\data\ecc_inf_hostname\data   Within the ecc_server.ini file look for the line: smtphost = xxx.xxx.com  replace the old name smtp server name xxx.xxx.com with the new smtp name. Save the file and restart the ControlCenter Server service  If you are still not getting e-mails  From the command line on the ControlCenter server host, run the following command:   c:> telnet xxx.xxx.com 25 The result should show similar to the following: (having the FQDN of the SMTP mail server)   220  server.xxx.xxx.com Microsoft ESMTP Mail Service, Version  Check the SMTP configuration is ok by running the tests in emc167243 & emc50784    Regards Conor 
 we have ECC 5.2 SP5 (yes I know it's old, we are awaiting an upgrade) our mail guys have changed the SMTP-relay IP address and hostname (without telling us)  obviously we are no longer receiving Emails  our documentation says this is set during the install but I cannot find anywhere where it says you can change it later  it must be in a config file somewhere  any ideas ?  regards  Alick
