Technical details
Accounts and mail flow
We inventory mailboxes, shared addresses, forwarding and quota requirements. User permissions and client connections are configured, with clear procedures agreed for new starters, departing employees and the management of shared company mail.
Sender authentication and filtering
We align domain SPF, DKIM and DMARC records with the mail provider. Supported spam, malicious attachment and phishing controls include procedures for reviewing quarantine and incorrectly blocked messages. We explain how users can recognise suspicious messages and report incidents.
Migration, checks and maintenance
We assess existing mail volumes, folders and client settings before planning the migration sequence. Sample transfers, DNS changes and sending and receiving tests are performed, with error records and maintenance needs kept in a structured tracking file.
