Hi Eric, the mail.* options specify which SMTP server should be used to send outgoing mail. You you pointed mail.server to localhost, which means you'll be running an SMTP server on localhost. You installed sendmail, but in most cases, instead of standalone mode it should be configured as a smarthost, which means it will in fact use another SMTP server in your network (look at SMTP configuration in your e-mail client, you could and probably should use the same in DSpace configuration).
If you still have doubts which SMTP server to use, you can test with the Gmail SMTP account [1]. But I don't really recommend it because it likely has quotas on outgoing mail. One point you probably missed is that mail.server.username and mail.server.password are username/password for your email account, i.e. the ones sent to SMTP server for authentication. Not your DSpace credentials. So, to sum it up, you have the following options, in the order from most recommended to least: 1) Set up mail.* with an existing SMTP server in your network (look at your email client configuration) 2) Set up mail.server to localhost, configure sendmail as a smarthost to point to the SMTP server in your network 3) Set up mail.* with Gmail's SMTP server 4) Set up mail.server to localhost, configure sendmail in standalone mode [1] http://blog.stuartlewis.com/2009/09/05/using-gmail-with-dspace/ Regards, ~~helix84 Compulsory reading: DSpace Mailing List Etiquette https://wiki.duraspace.org/display/DSPACE/Mailing+List+Etiquette ------------------------------------------------------------------------------ Everyone hates slow websites.
