Support your business communication with reliable, secure and professional email infrastructure. Custom domain email, advanced spam/virus protection, DKIM/SPF/DMARC configuration, webmail access, archiving and IMAP/POP3/SMTP protocol support.
Corporate email is the foundation of your business's professional identity and trusted communication. Free services like Gmail or Yahoo fall short for corporate reputation, while a poorly configured mail server risks spam folder delivery, transmission errors and security vulnerabilities. Atria Technology Corporate Mail Server service offers the ideal balance between these extremes.
Our service creates and manages corporate email accounts in @yourcompany.com format. Our Postfix/Dovecot-based mail server infrastructure is protected with multi-layer spam and virus filtering (Rspamd, ClamAV), greylisting and rate limiting. DKIM digital signatures, SPF sender verification and DMARC policy configuration protect your emails from spam marking and spoofing attacks.
Webmail interface (Roundcube) provides browser-based email access; IMAP, POP3 and SMTP protocols offer full compatibility with Outlook, Thunderbird and mobile devices. Calendar, contacts and task management (CalDAV/CardDAV) support simplifies team collaboration. Email archiving module stores all inbound/outbound messages in indexed, searchable form for legal requirements and corporate compliance.
