Mail Relay

OPLIN offers Ohio public libraries access to an authenticated mail relay. 

Public libraries are welcome to relay email from ILS, appliances, cloud platforms, or other sources. OPLIN's mail relay requires SMTP authentication, encryption, and accepts mail for relay from any source. Older cipher suites and TLS/SSL versions are supported to enable libraries to send email from older appliances and devices with embedded firmware that is incompatible with modern cloud email services.

OPLIN's mail relay supports custom configuration, including rate limiting, unique accounts per source, large attachments, and monthly statistics and deliverability reports.

If a library wishes to send SMS notifications from a cloud-hosted mail solution, use of OPLIN's mail relay is required. 

OPLIN can also provide guidance about configuring the library's DNS records to improve email deliverability.
