Using "sendmail-8.14.1-2" version of sendmail on my Fedora 7,i 386 OS platform.

I am using "RoundCube" Webmail as a GUI service to send/receive mails.It supports only IMAP Protocol as an Open Source Project.

Now,I want to restrict User Quota in Sendmail as well as User Mail Attachment size. Native sendmail documentation isn't providing all stuff.

So,I would like to know that How to limit User Quota & Attachment size?

It is also true that Sendmail uses native linux OS users as a Mail service,So I can implement User Quota & Group Quota also.

But,first tell me the easiest way.If User Quota is the final solution for User limit,then I will do it.

Please let me know how to restrict User Mail Attachment size in sendmail?

Waiting,

Hi,
Currently i am not using sendmail. But for attachment size, following is the parameter to change...

define(`confMAX_MESSAGE_SIZE',maxsize)

Eg:

define(`confMAX_MESSAGE_SIZE',10485760)
(10Mb in bytes)

As you are are using roundcube, check your php.ini file for the following parameters.

upload_max_filesize
post_max_size
memory_limit


Test this in a test environment.


Regarding the quota, usrquota and grpquota is the only known option to me.

Dear Friend,

I did the same in Sendmail "to restrict attachment size" & i have made changes in "roundcube" also.

Though "roundcube" is based on php , I modified /etc/php.ini file for the same.

Thanks for your support,

Nishith Vyas.
