CodeTwo Email Signatures On-prem
What CodeTwo Email Signatures On-prem is
CodeTwo Email Signatures On-prem manages email signatures, disclaimers, content rules and mail flow for Microsoft Exchange. It runs locally without cloud agents and supports Exchange Server Subscription Edition with the Mailbox role and hybrid Exchange environments. Administrators manage organization-wide rules through a central panel, including remote administration and replication across servers. An HTML editor, Active Directory data and inline graphics support company signatures. Rules can rewrite addresses or subjects, forward or reroute messages, and remove, compress, archive or add attachments. Sensitive-content scanning uses dictionaries, wildcards and regular expressions, with options to remove, mask or replace matches. S/MIME and Active Directory Rights Management Services protection are supported, while PGP and OpenPGP are not. Hybrid Sent Items Update uses Microsoft Graph and OAuth 2.0. The yearly subscription requires at least 25 licenses, and includes updates and technical support. A 14-day trial is available.
