What IMAP and SMTP do
These are the two standard protocols nearly every email host supports:- IMAP reads mail from your provider so incoming messages appear in Revenue Sol.
- SMTP sends mail through your provider so replies leave from your real business address.
What you’ll need
Gather these details from your email provider before you start. You can usually find them in your host’s help docs under “email client setup” or “IMAP/SMTP settings.”| Setting | Typical value |
|---|---|
| Email address | your full business address |
| Username | usually your full email address |
| Password | mailbox or app-specific password |
| IMAP server (incoming) | e.g. imap.yourhost.com |
| IMAP port | 993 (SSL) |
| SMTP server (outgoing) | e.g. smtp.yourhost.com |
| SMTP port | 465 (SSL) or 587 (TLS/STARTTLS) |
If your provider uses two-factor authentication (Gmail, Outlook, and many others), your normal login password will not work. Generate an app password in your email account’s security settings and use that instead.
Connect your mailbox
Open channel settings
Go to your settings and choose to add a new email channel, then select the IMAP/SMTP (custom mailbox) option.
Add the outgoing (SMTP) server
Enter your SMTP server address and port, with SSL or TLS as your provider specifies.
Troubleshooting connection issues
Authentication failed or wrong password
Authentication failed or wrong password
Double-check the username (it’s usually your full email address, not just the part before the @). If your provider enforces two-factor authentication, switch to an app-specific password instead of your normal login.
Connection timed out or refused
Connection timed out or refused
Verify the server hostnames are spelled exactly as your provider lists them, and confirm the ports: IMAP 993, SMTP 465 or 587. A wrong port is the most common cause of a timeout.
Mail receives but won't send (or vice versa)
Mail receives but won't send (or vice versa)
This points to one half of the setup. Re-check the SMTP server and port if sending fails, or the IMAP server and port if receiving fails. Some hosts use a different port for STARTTLS (587) than for SSL (465).
Provider is blocking the connection

Some hosts require you to explicitly enable IMAP access or approve “less secure” / third-party app sign-ins in your mailbox settings. Enable that option, then retry the test.
