I have a problem with this.
I cannot imagine any scenario which would justify sending out 400 000
e-mails with a 1Mb attachment. The chaos that this will cause to your
recipients and the ISP's that host their e-mail will be very
significant. You are likely to find yourself subject to many
complaints, and a listing on "Spamcop" is a distinct possibility.
So before you look at the technicalities of sending the e-mail
server, try and answer the following first:
- Have all 400 000 people indicated their willingness to receive
this
e-mail? I can't believe they are employees of an organization,
and
even if they are clients of a bank or insurance company, it does
not
mean they would all be happy to get your e-mail.
- Does the attachment have to be 1 Mb? Unless it contains essential
graphs or maps, it should be possible to make is smaller. 1 Mb of
text can hold a very large amount of information.
- Would it not be better to distribute the file from a web site or
ftp
site, and e-mail a link from where it could be downloaded?
I manage an e-mail list on behalf of a club. There are about 100
paying members on the list which is used to distribute a news letter
about once a month. Some members are keen to see some pictures in the
news letter - which obviously adds to it's size. If the file size is
held at 500 to 700 kb it usually goes through without problems. If
the file size exceeds 1 mB we have had up to 30% bounces, complaints
and a variety of other problems. Every issue I have to negotiate with
the editor to get the size reduced! (This is the size of the file
that gets attached, the e-mail is significantly bigger.)
Good Luck
