Amazon SES attachment error for ICS files

Question

I am facing attachment error with Amazon SES service. Normal `pdf` or `jpg` files are attached properly. But when i attach a `.ics` file which is a calender file. I got this error. ``` 554 Transaction failed: Illegal filename 'file_name.ics' ``` I am using `aws-ses` gem with `rails 3.2.2` Is there any limitation from Amazon? And how can we request them to allow this mime type to our account?

Accepted Answer

The actual issue was that the email has content type `multipart/mixed` and the part which holds the `ics` file has the cotent type `text/plain`, According to Amazon MIME Types, `text/plain` must have extensions `txt, diff, text`. But in my case it was having `.ics` extension.

So i have to change the code from this.

```
attachments["file_name.ics"] = @model.to_ical
```

to this.

```
attachments["file_name.ics"] = {:mime_type => 'text/calendar',
                                            :content => @model.to_ical}
```

and it solved my problem.
