Does LISTSERV support SPF/DomainKeys?

LISTSERV itself doesn’t know anything about SPF/DomainKeys, which are handled at the SMTP server level. It will, however, pass mail signed with these systems without altering the signature. LSMTP does not support SPF/DomainKeys, and L-Soft recognizes that this may cause a problem for people using LISTSERV’s mail-merge feature. Therefore, starting with LISTSERV 14.4, LSMTP is no longer required for mail-merge operations. LISTSERV’s Embedded Mail Merge feature means that you can now send all your mail-merge traffic through an SMTP server that supports SPF/DomainKeys signing.
