How many addresses can be put in the TO: line

[albatroz]

I wonder if there is any restriction regarding this:
How many email addresses can be put in the TO: line

I ask because a customer recently tried to send an email
with large list email addresses unsuccessfully..
(no it wasn´t a sort of spam)

Thanks in advance

If we don't know we can't tell you.

Was the client using webmail, or his own email client, or a program on the server?

You should probably never put any addresses in the To field of a multiple-recipient mailing; if you do every recipient will see every other recipient's email address.

Some email clients make you put in at least one.

Exim, the mailserver used by DA, doesn't even understand the concept of a To field. It understands the envelope recipients which are constructed from the To, CC and BCC fields by your email client.

If you're using a program requiring you to put addresses into a To field you're probably using the wrong software for a mailing list.

My customer is using Outlook Express email client. The problem is that he is coming from a provider using Postfix where it seems that this was working OK.

You still haven't told us if he gets an error, or if it appears to work but the email disappears.

You may need to find the error in the /var/log/exim/error.log file.

Once you know the error you might want to google it, or post it on the exim-users mailing list to see if you can get a response there.
