Mail bounces or is rejected
A recipient rejects messages, the sender receives an error or the mailbox cannot send after a provider or DNS change.
Business email repair
When important email stops arriving, trace the delivery path without guessing.
Business email can fail because of mailbox settings, DNS records, authentication, forwarding rules, storage limits or changes around the domain. SiteRescueNow starts by identifying the reported delivery path and the evidence available, then gives a clear repair decision before changes are made.
Keep passwords, recovery codes and email contents private.
For the first report, share the affected domain, sender or recipient domain, bounce message if any, when the issue started and whether the domain, DNS or provider changed recently.
What we investigate
Delivery failures that affect customers and operations.
Messages disappear or land in spam
Expected messages are not visible, forwarding fails or legitimate business mail is repeatedly filtered.
Domain changes affect email
MX, SPF, DKIM or DMARC records can be missing, outdated or inconsistent after DNS or hosting work.
A careful path to repair
Work from evidence and protect business communication.
Describe the exact symptom
We use the affected address, timing, bounce message and recent changes to narrow the delivery path.
Check the relevant systems
We assess mail provider, domain and DNS settings that are relevant to the reported failure.
Decide on the repair
