Something related to mail servers

kcpant — Sat, 17 Dec 2005 06:15:42 GMT

Dear Friends,

We can setup sendmail+Mailscanner to reject mails with attachments larger than a specified size, say, mails larger than 2 MB will be rejected. We can also notify the sender of such mail. Is there any mechanism by which we can notify the reciepient that the mail of larger attachment sent to him/her has been rejected by mail server?

Thanks in advance, 10 pointer for every good logic...

Thanks & regards

Shalom kcpant,

Couple of ideas for you. The web based mail package squirrelmail has a 2 MB attachment default, though its not really good at the notification part.

A good place to reaserch this is http://www.senmdmail.org

Its a really comprehensive place to explore sendmail issues.

Check the Mailscanner.conf file. I believe
you can send notifications to both the
sender and recipient.

Easy - in /etc/mail/sendmail.cf

Uncomment line:

# 0 MaxMessageSize=1000000

this is the maximum message size in bytes

0 MaxMessageSize=2000000

Hi Bill,

I'm working with MailScanner & Sendmail combination from quit a long time, but haven't found a way to do the task (notification to recepient). I know notifications can be configuredf in mailscanner for each & every error, but to the sender only. can you please let me know if there is any way to set mailscanner to send notification to the recepient also?

thanks in advance.
