Compress attachments

[andreas . moroder]

Hello,

I found older (1998 ) posts about mailbox or attachment compression,  
but no answer to my question.

Is it possible to configure cyrus the way that it compresses the  
attachments on the storage ( not for tranfer as in RFC 4978 ) ? I know  
that diskspace is cheap, but when you have to get back thousands of  
mailboxes from a backup, the smaller the files are the faster the  
restore is done.

Thanks
Andreas

Re: imp webmail, cyrus imap and virus filtering

[Andreas Moroder]

 
 
  You mean mail already already in your INBOXes received before you have
  installed your trendmicros filter, or mail sent internally by your
  user ?
 
  In the last case the simple solution is to ask your user to send email
  directly to your trendmicro !
  If this is not possible you can configure your trendmicros as a filter
  for your postfix !
  But if you want keep your trendmicro in front for your incoming email,
  and have postfix in front for your local users, this is an unusual
  configuration, ask the postfix mailing list for information to do that
  !

Hello Alain,

I reanalyzed our actual configuration and found that the problem is more 
limited,because when I send a mail via imp webmail then imp passes the 
mail to postfix and the antivirus.

The problem that remains is about drafts. When a user saves a mail as 
draft, then it is not sent but simply stored by cyrus. This way the mail 
is not scanned. The user can use the drafts as a file storage and then 
recall the files from another PC. Is there a solution for this case ?

Thanks
Andreas

imp webmail, cyrus imap and virus filtering

[andreas moroder]

Hello,

we have a imp/postfix/cyrus system. The mail that goes out and comes in
from/to our system via smtp is checked by trendmicros virus wall.

The problem is mail that remains in our mailsystem and is accessed via
imap from imp. Viruswall has no way to check this mail.

Is it possible to write a sieve filter to start a virusscan on this mail
( by scanning the specific file in the users mail directory ? ) every
time a mail is created or read via imap ?

Thanks
Andreas
