Answering Questions

MattSpew said...

I don't have any questions..

The only comment I can think of is that Sendmail isn't a protocol nor is it a nick name for the protocol SMTP.

SendMail is an OpenSource Unix based email agent/server. http://www.sendmail.org/

  • I shall change my blog now to correct this.

why does SMPT have trouble queuing messages when a server recieves email?

  • Sharon gave me a very good statement about this. Please read her comment.

Further to your statement about SMTP's ability to queue mail, I discovered the following information on http://www.freesoft.org/CIE/Topics/94.htm

"If mail delivery fails, sendmail (the most important SMTP implementation) will queue mail messages and retry delivery later. However, a backoff algorithm is used, and no mechanism exists to poll all Internet hosts for mail, nor does SMTP provide any mailbox facility, or any special features beyond mail transport. For these reasons, SMTP isn't a good choice for hosts situated behind highly unpredictable lines (like modems)."

Do you agree with this statement?

Hey Bennji
Is SMTP the only program they use on the net for sending email or only the most widely used also are there any provider this won't work with or is it universal.
  • SMTP is the most common protocol. After much research, I could only find one other alternative:
    • Local Mail Transfer Protocol (LMTP), which will reject recipients who cannot receive data immediately, so this removes the need for a mail queue.
SMTP seems very much the most common. Finding information about other MTPs is quite troublesome.

SMTP

Simple Mail Transfer Protocol
Simple Mail Transfer Protocol (also known as 'sendmail') is the most common protocol used today for transfering e-mail over the internet. Most email systems uses SMTP to send emails from one server to another, and POP3 / IMAP to receive the emails.

Simple Mail Transfer Protocol ('SMTP'), among other things, defines the message format, specifies how two mail systems interact, and originally SMTP was only text-based (ASCII) but MIME and other encoding methods have allowed executables and multimedia to be sent along with the email (attachments).

SMTP uses a TCP/IP protocol, but is limited in its ability to queue messages when a server receives email. The most common protocols used to receive email are POP3 and IMAP (which allow users to save the emails received in the server and allows them to download them at a later date).

Comparison of 2 FTP Programs

FTP Programs; FileZilla vs. SmartFTP

Filezilla and SmartFTP are both excellent FTP programs and are both effective at what they do. However, there are some key differences between the two, which will be very important in which one you will choose.

FileZilla
FillaZilla is Open Source, small and fast. It is very good for more advanced users who want to edit the source code of the program and make changes.

SmartFTP
SmartFTP has a much better interface, is alot more appealing (eye-candy wise) and seems to have more to offer compared to FileZilla. However, they both have the same options, and SmartFTP just seems to look better, offering not much else.

Result
Both programs are fine for simple FTP, but FileZilla, although not as nice looking as SmartFTP, can have its source edited, which would mean more modifications would be available then SmartFTP.

FTP Commander

FTP Commander
http://www.internet-soft.com/ftpcomm.htm

FTP Commander had 3 different versions, with all 3 based for 3 different types of users.

FTP Commander

FTP Commander is the simplest FTP that the company 'Internet Soft' offer. According to their main site;

"FTP Commander is a simple and easy to use ftp client. It's really the bare minimum with no extra frills or thrills. It offers a no-nonsense interface consisting of two side-by-side local computer and FTP server panels. The latter contains a list of about a dozen pre-set FTP servers. It's easy as pie to establish a connection."

FTP Commander Pro
FTP Commander Pro is for the more advanced users who want to FTP. According to their site;

"That's basically it because anything else would just be overkill. Overkill comes in handy when you're running a professional website equipped with a search engine, database, scripting facilities executed on a server or other such large-scale functions. In this case you'll need to assign access permission to remote servers, synchronize directories that will enable you to take advantage of many other splendid options offered under the new version of
FTP Commander Pro (ftp client) program."

FTP Commander Deluxe

"For business sites, as opposed to private home pages, information security comes into play. Can you estimate the possible losses in case your web site is hacked? Chances are that the loss would be painful. With this in mind, you should remember the one big FTP-protocol disadvantage: data is transmitted in an un-encrypted form."
