When a series of messages are sent using the same SMTP connection, is
there a variable which gives the message number in the series and is this
available for use in ACLs. I want to know which is the first and which are
the later ones, in particular.
We have a specialist bulk mailer which sends all the message to people
individually but via the same SMTP connection. For performance reasons we
have increased the smtp_accept_max_per_connection. However the issue is
that once we have virus scanned the first, I would like to send the others
through without scanning [same message].
I think I can see how to do this by setting my own variable and testing it
in the data acl assuming these are not cleared between messages. However a
system messages number to test would be better.
If anyone has done this, please let me know how you did it.
Sorry if this is in the manual but could not see it. Page number please.
