Subject: Limits to "cc"?

From: [email-masked] (Gary Farber)

I'd like to know what the limit is as to how many people you can put into 
the "To:" line, as well as the "cc:" line and "Bcc:" line.  I've had 
trouble sending to over 25 or so people at a time per line, but haven't 
been able to figure out a precise limit.  I couldn't find anything in the 
man pages about it.  What do you know?  Or is this a "sendmail" total 
limit, and if so what is the total limit?  Does it matter how one divides 
the names between those three "send" lines?

Thanks in advance for everyone's help.  :-)

Hi Gary

One solution to your problem would be to create a Distribution List.  
While in your Address Book, press "s" to "CreateList".  You give it a 
name and then you can add all the names you wish.

> name and then you can add all the names you wish.

I've done that, and while I've not tested the limits of it, it was my, 
perhaps erroneous, understanding that this is the same as listing the 
names manually so far as sendmail is concerned.  The Address Book merely 
deals with inserting addresses into the "send" slot of your mail -- not 
with what comes afterwards.  So my understanding is that this would add 
nothing.  Am I wrong?  If so, that would be valuable to know indeed.

Either way, many thanks for your kind response.  :-)

Hi Gary

I see from my own Distlists that it does show all the addresses!  Sorry.  
The advantage of a distlist is that you don't have to manually put the 
addresses in everytime you want to send mail to a certain group of 
people.  That's a lifesaver!! :-)

Maybe you have to be a LISTSERV or a mailing list like "pine-info" in 
order to do it without having all the names appear!  This is a good question 
to ask the owner of this mailing list!  Sooo, owner of pine-info mailing 
list, can this be done??

I strongly suspect that your problem is not within Pine, but in the 
version of sendmail (the mail delivery system used on most UNIX 
computers) run on your system.

A security hole was uncovered in sendmail that led to the release of a 
revised version.  Most system administrators respond very quickly to 
security holes and installed the new version.

Unfortunately the new version of sendmail "broke" messages being sent to 
more than about 20 recipients.

When Pine tries to pass such a message to sendmail, sendmail crashes 
which Pine duly reports.

The problem was fixed in (if I recall correctly) sendmail 8.6.12.  
Unfortunately system managers are often not so prompt at installing new 
versions of software where security is not compromised in the old one :-)

You should contact your system manager and ask them to check that they 
are running sendmail 8.6.12 or later.

Cheers,

As I recall there was indeed a version of sendmail, perhaps around
8.6.9, with a bug that caused this problem.  The fix is to upgrade
sendmail.
