Email Client Setup (IMAP & SMTP)

Mailofly Business Mailboxes are 100% compatible with standard desktop, mobile, and web email clients. You can sync your inbox, sent items, and drafts across Apple Mail, Microsoft Outlook, Thunderbird, and smartphone email apps.

​
Universal Server Connection Settings

Keep these connection parameters handy when setting up any email application:

​
Incoming Mail (IMAP)

  • Server Hostname: mail.mailofly.com
  • Port: 993
  • Security / Encryption: SSL/TLS
  • Username: Your full email address (e.g. alex@yourdomain.com)
  • Password: Your mailbox password
  • Authentication: Normal Password

​
Outgoing Mail (SMTP)

  • Server Hostname: mail.mailofly.com
  • Port: 587 (STARTTLS) or 465 (SSL/TLS)
  • Security / Encryption: STARTTLS or SSL/TLS
  • Username: Your full email address (e.g. alex@yourdomain.com)
  • Password: Your mailbox password
  • Authentication Required: Yes (same credentials as incoming)
[!TIP] Always use mail.mailofly.com as the incoming and outgoing server hostname (rather than your custom domain name) to prevent SSL certificate mismatch errors in native mail clients.

Troubleshooting Common Issues

​
”Unable to verify account name or password”

  • Ensure you are entering your full email address (user@yourdomain.com) as the username, not just the local prefix (user).
  • Check if your mailbox is paused by an admin in the dashboard.
  • If you recently reset your password, restart your mail app or remove and re-add the account.

​
”Cannot connect to outgoing server”

  • Many residential and cellular internet service providers block outgoing traffic on port 25 to stop spam bots. Mailofly requires Port 587 (STARTTLS) or Port 465 (SSL/TLS) for client sending. Never use port 25 in client apps.

​
”Certificate Warning”

  • If your client alerts you to a hostname mismatch, ensure you typed mail.mailofly.com rather than your vanity domain (e.g. mail.yourdomain.com). The server’s TLS certificate matches mail.mailofly.com.
