Question regarding how to handle large tables with many rows: 


Where should the delete option be? I see many examples placing the delete icon or text on the far-right of the row. Is this best practice? Is it always advisable to swap row delete to checkbox selection/batch delete?
If a table row has multiple available actions such as [Edit | Publish | View History ] etc, should these items be grouped into a single "Actions" row item? 



Question: how to send a mail by telnetting through some SMTP server?
Answer: That looks like two distinct questions...

SMTP is a fairly simple protocol (at least for just sending an email)... once you open a telnet connection on the right port you just need to issue the commands:

From Wikipedia: (commands you issue are prefixed with "C:" the servers responses with "S:")

S: 220 smtp.example.com ESMTP Postfix
C: HELO relay.example.org
S: 250 Hello relay.example.org, I am glad to meet you
C: MAIL FROM:&lt;bob@example.org&gt;
S: 250 Ok
C: RCPT TO:&lt;alice@example.com&gt;
S: 250 Ok
C: RCPT TO:&lt;theboss@example.com&gt;
S: 250 Ok
C: DATA
S: 354 End data with &lt;CR&gt;&lt;LF&gt;.&lt;CR&gt;&lt;LF&gt;
C: From: "Bob Example" &lt;bob@example.org&gt;
C: To: Alice Example &lt;alice@example.com&gt;
C: Cc: theboss@example.com
C: Date: Tue, 15 Jan 2008 16:02:43 -0500
C: Subject: Test message
C:
C: Hello Alice.
C: This is a test message with 5 header fields and 4 lines in the message body.
C: Your friend,
C: Bob
C: .
S: 250 Ok: queued as 12345
C: QUIT
S: 221 Bye
