Catch-all detection alone has paid for the subscription. We were hemorrhaging credits at our previous verifier on catch-all domains that accepted the call but never bounced. Saved roughly $400 per month overnight. Brett Anderson · RevOps Manager

roche.com Email Authentication SPF · DKIM · DMARC
SPF
Sender Policy Framework. A DNS record listing which servers are allowed to send mail for this domain. Receivers reject or flag mail from unauthorized servers.
Pass
TXTv=spf1 redirect=roche.com.hosted.spf-report.com
Authorized senders are defined and pass SPF policy.
DKIM
DomainKeys Identified Mail. The sending server cryptographically signs outbound mail with a private key, and receivers verify the signature using a public key in DNS.
Pass
SELECTORDetected via standard selectors
A DKIM signature was detected. Outbound mail from this domain can be cryptographically verified.
DMARC
Domain-based Message Authentication, Reporting & Conformance. Tells receivers what to do when SPF or DKIM checks fail: none, quarantine, or reject.
Reject
TXTv=DMARC1; p=reject; rua=mailto:88a488cb@mxtoolbox.dmarc-report.com,mailto:dmarc@ayba8dhs.uriports.com; ruf=mailto:88a488cb@forensics.dmarc-report.com,mailto:dmarc@ayba8dhs.uriports.com; fo=1; pct=100
Strict policy. Receivers are instructed to reject any mail that fails SPF or DKIM. The strongest available setting.

Common Questions About roche.com
Is roche.com a disposable or temporary email provider?
No. roche.com is not a disposable email provider. It is classified as Corporate Email operated by Roche Holding AG and addresses on roche.com are persistent rather than throwaway. Mail sent to a valid roche.com mailbox reaches a real recipient.
How do I verify if a roche.com email address is valid?
The fastest way to verify a roche.com email address is to use our free email checker. Enter any @roche.com mailbox at the top of this page and our system performs a real-time SMTP handshake against roche.com's mail servers, confirming whether the mailbox exists, is reachable, and is safe to send to. No email is ever delivered during the check.
Can I check if a roche.com email exists without sending a message?
Yes. Our real-time email verification API connects directly to roche.com's mail server, opens an SMTP session, and queries the mailbox using the RCPT TO command without ever transmitting an actual email. The server's response confirms whether the roche.com mailbox is valid, full, or non-existent. The recipient never receives anything and never sees the check.
What are the MX records for roche.com?
roche.com currently publishes 8 mail exchange (MX) records. The primary MX is rkamtaext02.roche.com, which is the first server contacted when other mail systems try to deliver email to a roche.com address. The full list with priorities and IP addresses is in the MX Records panel above. MX records tell sending servers where to route email for roche.com.
Does roche.com use SPF, DKIM, and DMARC email authentication?
roche.com enforces all three email authentication standards: SPF, DKIM, and DMARC (policy: reject). This is the gold-standard configuration. It means receivers can verify that mail claiming to come from @roche.com is genuine, and roche.com's DMARC policy of 'reject' instructs receivers how to handle messages that fail those checks.
Why do emails to roche.com bounce or get blocked?
Bounces from roche.com usually fall into three buckets: the mailbox doesn't exist (5xx user unknown), the inbox is full, or your sending domain isn't authenticated to roche.com's satisfaction. The fastest fix is to run each address through a free email verifier before you send, and to make sure your own SPF, DKIM, and DMARC are configured correctly so roche.com's receivers trust you.
How can I verify a large list of roche.com email addresses?
Our bulk email verifier accepts CSV or TXT uploads with thousands or millions of roche.com addresses (or any mix of domains). Every address goes through 30+ checks including SMTP existence, roche.com catch-all detection, role-account detection, and disposable-domain matching. Results typically come back within minutes and previously-failed addresses on your blacklist are reprocessed for free. For continuous high-volume needs, see our unlimited email verification API.
Is it safe to accept signups from roche.com email addresses?
Yes, with normal hygiene. roche.com is a legitimate email service and signups from @roche.com behave like any other real user. Pipe each address through a real-time email verifier API at the moment of signup to catch typos and dead mailboxes, but there is no need to block roche.com by default.
What email format does roche.com use for usernames?
Most roche.com mailboxes follow common patterns like first.last@roche.com, firstinitiallast@roche.com, or first@roche.com, but the actual local-part rules depend on Roche Holding AG. The only reliable way to confirm whether a specific @roche.com address exists is to run it through a free email verification tool. Guessing patterns will produce a high bounce rate and damage your sender reputation.
How is the roche.com risk score calculated?
The 0-to-100 risk score for roche.com combines disposable-domain classification, mail-server reachability, MX record presence and depth, SPF / DKIM / DMARC enforcement, DMARC policy strength, SMTP banner response, and domain age. Lower scores mean safer to send to. Disposable domains are pinned at the high end of the scale. The roche.com score is recomputed on every audit so it always reflects the live state of the domain.
Is roche.com a valid email domain?
Yes, roche.com is the official corporate email domain for Roche Holding AG. It is used for internal business communications.
Is roche.com a disposable or temporary email provider?
No, roche.com is a corporate email domain belonging to Roche Holding AG, used exclusively by employees and authorized personnel.
What mail server does roche.com use?
roche.com uses enterprise-grade mail infrastructure. Check the MX records section for specific mail server details.
Can I send marketing emails to roche.com addresses?
B2B marketing to roche.com requires proper consent. Corporate domains may use catch-all configurations, so verify individual addresses before sending.
How do I verify an email address at roche.com?
Corporate domains like roche.com may use catch-all configurations that accept all addresses. Use BulkEmailChecker advanced verification to detect catch-all behavior and validate individual mailboxes.
