Always use the full domain name in mailbox reply to addresses
Answer ID 6404   |   Last Review Date 09/09/2020

Can I use "mail@custhelp.com" instead of "mail@mailph.custhelp.com" in from and reply to addresses?

Environment:

Mailbox configuration, all versions

Resolution:

We suggest that you always use the full domain name when setting mailbox Reply To and From addresses to a current hosted server address. This applies to both Service and Outreach mailboxes.

Examples:
popaccount1@mailgb.custhelp.com
popaccount2@mailph.custhelp.com
popaccount3@mailmw.custhelp.com
popaccount4@mailsy.custhelp.com
popaccount5@mailva.custhelp.com
popaccount6@mailsy.rnmk.com

We also suggest that you change any old data center names such as mailuk, maileu, mailnj, mailwc, mailca to the name of your current pod name. Often times mailboxes are not reconfigured after a data center migration.

Cause:

While we do have redirects in place to handle mail sent to an address without a subdomain, such as @custhelp.com, it is not suggested to rely on those addresses. Always use the full name or mail may be directed to a data center that is in a different physical location than the one on which your site exists.  Then the mail may be filtered by the default settings in the spam filter on that data center.
