Mail.bg is one of the two dominant Bulgarian free consumer webmail services (alongside Abv.bg), operating since 1998 and one of the most-visited domestic websites in Bulgaria per public traffic rankings. To connect Mail.bg to Outlook, Thunderbird, Apple Mail, or a mobile client, use the settings below with your Mail.bg password.

SETUP GOTCHA ENABLE IMAP/POP3 IN WEBMAIL FIRST

Mail.bg blocks IMAP and POP3 access by default, external clients cannot connect until the protocol is enabled in webmail settings. This mirrors the pattern used by most Bulgarian and Eastern European free webmail services. Sign in to Mail.bg webmail, open Settings (Настройки), navigate to POP3/IMAP access, and enable the protocol you need. Once enabled, use standard hostnames: imap.mail.bg, smtp.mail.bg, and pop.mail.bg. Reference: SMTP 550 5.7.1 guide.

Quick Reference: Mail.bg Server Settings

ProtocolServerPortEncryptionAuthentication
SMTP (outgoing)smtp.mail.bg465 (SSL) or 587 (STARTTLS)RequiredFull email + password
IMAP (incoming, recommended)imap.mail.bg993SSL/TLSFull email + password
POP3 (incoming, single device)pop.mail.bg995SSL/TLSFull email + password

Mail.bg SMTP Settings (Sending Mail)

SMTP handles outbound mail. Server smtp.mail.bg on port 465 SSL, with port 587 STARTTLS as alternative. Authentication uses the full @mail.bg email address as username plus your Mail.bg account password. Consumer SMTP has undocumented rate limits typical of a large free webmail. Heavier transactional sending needs a dedicated SMTP relay.

Mail.bg IMAP Settings (Recommended for Reading)

IMAP syncs folder state across every device. Server imap.mail.bg on port 993 SSL/TLS. Folder names appear in Bulgarian by default but IMAP folder attributes let clients map them to Sent, Drafts, and Trash correctly.

Mail.bg POP3 Settings (Single-Device Access)

POP3 downloads mail to one device with no server-side sync. Use pop.mail.bg on port 995 SSL/TLS. Enable “Leave a copy on the server” in your client to prevent webmail from being emptied.

Frequently Asked Questions

How do I enable IMAP access on Mail.bg?

Sign in to Mail.bg webmail. Open Settings (Настройки), navigate to the POP3/IMAP or external clients section, and enable IMAP. Save changes. Your external client will now be able to authenticate against the Mail.bg IMAP server. The same page allows enabling POP3 if you prefer that protocol.

How does Mail.bg compare to Abv.bg?

Mail.bg and Abv.bg are the two dominant Bulgarian free webmail services, both dating from the late 1990s. Both hold millions of accounts and offer similar core features (free webmail, IMAP/POP3/SMTP, spam filtering). The choice is largely legacy-based, users tend to stick with whichever service they signed up with first, and both are reliable domestic options within Bulgaria.

How do I reset my Mail.bg password?

Sign in to Mail.bg and use the password reset flow from the login screen. Recovery goes through the backup email or Bulgarian mobile number registered on your account. If you have lost access entirely, contact Mail.bg support through the contact form.

How secure is Mail.bg email in transit?

Mail.bg enforces SSL/TLS on the encrypted mail ports (993, 995, 465) for client-to-server transport. Port 587 uses STARTTLS opportunistic encryption after connection. Server-to-server transport follows standard SMTP with STARTTLS. Bulgaria-hosted infrastructure under EU GDPR jurisdiction. For end-to-end message encryption use S/MIME or PGP client-side.
