Common topics
Domain & DNS configuration
- Add your domain in the portal and copy the generated MX, SPF, DKIM, and DMARC records into your DNS provider.
- Records show green when verified and yellow while pending — re-check after DNS propagates (minutes to a few hours).
- Keep only one SPF (v=spf1) record on your domain to avoid authentication failures.
Mailbox setup
- Create mailboxes (like info@ or support@) from the Mailboxes page, within your plan's limit.
- Each mailbox works instantly with webmail and any IMAP/SMTP email client.
- Use the 'Connect email' button on a mailbox for step-by-step Gmail, Outlook, and Apple Mail instructions.
Connecting email clients
- IMAP (incoming): imap.corezyn.in, port 993, SSL/TLS.
- SMTP (outgoing): smtp.corezyn.in, port 587 (STARTTLS) or 465 (SSL/TLS), authentication required.
- Username is your full email address; use your mailbox password.
Deliverability
- Publish SPF, DKIM, and DMARC exactly as shown to maximise inbox placement.
- New domains may land in spam briefly until sending reputation builds — this improves with consistent, wanted mail.
- Ask recipients to mark early messages 'Not spam' to speed up reputation.
