This is used for "ending" the DATA section (ie., the email message) of
an email transmission.

The mail data is terminated by a line containing only a
period, that is the character sequence "<CRLF>.<CRLF>" (see
Section 4.5.2 on Transparency). This is the end of mail
data indication.
The same holds true if interacting with the mail server via telnet to
port 25.
Sounds like something not right with email server or the program you
are using to fetch mail off the server.

Ethernet packets are limited to 1500 bytes in size (+ a few overhead
bytes) so this is "normal" behavior. Your network is not the source of
this problem.
RFC 821 provides for some wiggle room via the Transparency mentioned
above. But it's the duty of the software to handle dots "correctly".
Not familiar enough with Postfix configs to help you out here if this
is the source of your problem.
What do you use to fetch mail off the server? What is the MTA (mail
server) that your Postfix communicates with for internet mail? Are you
using any scripts or mail processing apps when fetching internet mail?
I'm not a mail guru, so hopefully the qualified will chime in with the
answer.
