Redmine

+1 for this.

It seems like a very easy change from looking at the source. Even ignoring files by extension would work.

I'm new to ruby... but I'll try to write a patch if I have time.

We have a lot of users sending mails to redmine tickets with included images in html signatures.

Each time we have to delete the attachments manually in the ticket. and each time we delete an attachment a notification is sent.

Some attachments that are not real ones must be ignored. Just looking the file extension is not sufficient.

I'm not an email RFC expert, but Looking in two mail sources :

From a mail source with a real attachment :

------_=_NextPart_001_01CB3E16.D938DEBE
Content-Type: application/msword;
    name="=?iso-8859-1?Q?R=E9union_du_18082010=2Edoc?=" 
Content-Transfer-Encoding: base64
Content-Description: =?iso-8859-1?Q?R=E9union_du_18082010=2Edoc?=
Content-Disposition: attachment;
    filename="=?iso-8859-1?Q?R=E9union_du_18082010=2Edoc?=" 

From a mail source with an included attachment :

------_=_NextPart_002_01CB3D29.23FDF48F
Content-Type: image/gif;
    name="image001.gif" 
Content-Transfer-Encoding: base64
Content-ID: <image001.gif@01CB3D39.E7847940>
Content-Description: image001.gif
Content-Location: image001.gif

In the "real" attachment, there is a "Content-Disposition: attachment;" ligne.

Maybe it's the way to detect real attachments from others ?

i agree that filtering based on mime makes sense in the long run, but for now a small patch would be appreciated. just a comma-seperated list of extension to ignore, defaulting to the very obvious ones: vcf,p7s and other signatures.

We are in the same case and issues are pollute with a lot of signature attachment.

we have the same problem (company logo included in signature)

This feature would be great.

S/MIME & company logos could be handled with a configurable filename match in the admin/settings/incoming-email panel.

e.g.

smime.p7s
*.vcf
my_company_logo.jpg

As for filtering out "inline" attachments, I would strongly disagree. Some email clients (like Apple's "Mail" app) automatically make attached images inline.
