+ | ===== Application Passcode (Outgoing - SMTP) ===== | ||
+ | |||
+ | SMTP sending is done via Ironport gateway which authenticates users against Zimbra mailserver so it is necessary to generate one extra application passcode which will be then assigned to Ironport communication with Zimbra (Zimbra cannot distinguish among your SMTP clients connected via Irinport, hence only one code can be used) | ||
+ | |||
+ | Steps: | ||
+ | |||
+ | 1) Log into your Zimbra account → Preferences → Accounts → Primary account settings → [Add Application Code] | ||
+ | |||
+ | 2) Name the new Application Code somehow descriptive (e.g. " | ||
+ | |||
+ | 3) Display Application code and WRITE IT DOWN (you will need it later if you want to add another SMTP client). | ||
+ | |||
+ | 4) DO NOT CLOSE windows with displayed code until you do the proper authentication via your SMTP client (see the following steps) | ||
+ | |||
+ | 5) Set SMTP as follows: | ||
+ | |||
+ | - Server Address: mailgw.cerge-ei.cz \\ | ||
+ | - Connection Security: STARTTLS (or Auto) \\ | ||
+ | - Port: 587 (default) \\ | ||
+ | - Authentication Method: Normal password (ordinary PC/network password) | ||
+ | |||
+ | 6) Enter your username without domain (e.g. **jdoe** | ||
+ | |||
+ | 7) Into password field put the Authentication code still displayed in Zimbra web interface (use CAPITAL letters) | ||
+ | |||
+ | 8) Save configuration and test sending email. | ||
+ | |||
+ | 9) You may close the Access Code window If email is successuly sent. | ||
+ | |||
+ | 10) If you want to add another SMTP client for your account, just reuse the Authentication code written down and follow steps 5 to 8 | ||
