Read and send email

Your webmail#

1. Open https://webmail.newtata.com.
2. Enter your full address and mailbox password. The portal account is separate.
3. Use Compose to send a message. Add the recipient, subject, text and optionally an attachment.
4. Find folders, contacts and settings in the menu. On a phone, panels open one at a time.
5. Sign out after using a shared device.

Useful limits#

Use the full address as username and the same password for IMAP and SMTP. Authentication is required for sending.

Attachment limit is 20 MB per file and 35 MB per encoded message. Sending is rate limited to prevent abuse; this service is for correspondence, not bulk campaigns.

DKIM, SPF and DMARC improve authentication but do not guarantee inbox placement. IP reputation and recipient filters also matter.

Gmail rejected a message: error 550 5.7.26#

This error means the recipient did not validate domain authentication. The portal now configures MX, SPF, DKIM and DMARC automatically after your first mailbox is created. Check status in Mail: wait for Email ready before resending.

After publishing, external servers may temporarily cache the previous absence of a record. Timing also depends on negative DNS caching, which can reach one hour with current settings. A message already returned to its sender is not resent automatically: resend after DNS refresh.

If rejection persists, give support the code and delivery report. Do not send the mailbox password.

Reduce spam placement#

SPF, DKIM, DMARC, TLS and a consistent server identity are configured to authenticate messages. They never guarantee inbox placement: each recipient applies its own filters and reputation checks.

Use a clear sender name, specific subject and content expected by your contacts. Avoid bulk campaigns, purchased lists and sudden volume increases on a new email service.

If a contact expected your message but finds it in spam, they can mark it as not spam. Do not try to bypass filters with repeated sends.

Delivery reports distinguish SMTP rejection from accepted messages later classified as spam. No portal setting can force inbox placement at Gmail or another provider.

Forgotten password or full mailbox#

The customer account owner can set a new password in Mail → Mailboxes. It is never displayed or resent after saving.

If the mailbox is full, free space, especially in Sent and Trash. Senders can resend quota-rejected messages once space is available.

Software and operations#

Newtata webmail uses Roundcube customised for this portal. Software notices and licences are retained.

Availability currently depends on a single server. Local operational backups do not replace an independent backup on another server; that additional storage is needed before large-scale commercial opening.
