Mistakenly Located Info Moved from Here
Material appropriate to Talk:Marcel Cerdan but irrelevant here has been moved to that location (via a history-merging operation). It is possible your were provided a link to here because of your interest in information that is now there.

Removed External Link
The following links
 * Marco D'itri, Sendmail considered harmful (Italian; babelfish)

were removed from the article for the following reasons: --Jerzy(t) 22:00, 2004 Aug 18 (UTC)
 * 1) No information beyond its title has been offered even attempting to verify its relvance.
 * 2) This is an English language resource.
 * 3) Babelfish cannot be relied upon to produce English worth the effort of reading it, let alone valid or accurate information in English.
 * 4) The apparent absence of any true English translation of the document in question, and of any English discussion of it, suggests the Unix community regards it to be without value.

I've read that there is a commercial version of sendmail that is a year ahead of the open source version. Since this is a unique and interesting approach within the open source movement, I wonder if someone familiar with the project could write about that part of the sendmail story. KellyCoinGuy

--- No, it's the other way around: the open source version is ahead of the commercial version.

pov
is that bit about sendmail X not a bit of POV? It basically accuses the sendmail author of copying another product without much in the way of foundation??

Removed one link as it throws the 403 error Forbidden You don't have permission to access /~ca/email/sm-X/design-2004-09-20/main/main.html on this server.

Apache/1.3.37 Server at www.sendmail.org Port 80

commande
That bit about sendmail X is totally off-base. I think that whomever wrote that has never seen other modular mail software that predates Postfix/Vmailer. What about MMDF? Even PMDF on VMS is fairly modularized. This seems to be nothing more than blatent sendmail bashing to me.

I edited the text to remove the biased info and it was reverted back to what is is now. Somebody really doesn't like sendmail.

Use of Sendmail as an open relay honeypot
In earlier versions of sendmail the program could be used as an open relay honeypot by invoking it with the command line

sendmail -bd

Sendmail would accept all mail and deliver none (no -q5 or the like.) That's useless or worse for a production email system but if done on a computer with no legitimate email function at all it created a simple way to capture the open relay test messages routinely used by spammers to detect open relays. The operator of the honeypot could periodically examine the mail queue and, if in the mood, cause an open relay test message to be forwarded, as originally desired by the spammer. Soon thereafter, usually, the mail queue would begin filling with a lot of actual spam. One practitioner somewhere in Asia captured and kept from delivery spam to about 750,000 recipients per day (average) over a several months period. Not that many individual spam messages: at that time spammers would send one message to 20 or more different recipients, to be relayed by the open relay being abused.

In later versions using sendmail as a honeypot got a bit more complicated. It may be pointless to even try now (2006) but in any evfent don't try unless you know what you are doing.

Mostly, though, the purpose of this brief note is to explain my alias (get it?) I advocated what I describe above.

Microsoft SMTP
The History and Use section lists "Microsoft SMTP" as the 2nd most popular mail server on the net. I changed it to "Microsoft Exchange Server" even through the source article does not name it specifically.

Sloppy website
The latest release appears to be 8.14.0, but this is not mentioned anywhere on the official site except as a "news" blurb. The download page still links 8.13.8 as the latest release, and 8.14.0 was released back in January. VanishingUser 23:38, 25 March 2007 (UTC)

Fair use rationale for Image:Sendmail logo.gif
Image:Sendmail logo.gif is being used on this article. I notice the image page specifies that the image is being used under fair use but there is no explanation or rationale as to why its use in this Wikipedia article constitutes fair use. In addition to the boilerplate fair use template, you must also write out on the image description page a specific explanation or rationale for why using this image in each article is consistent with fair use.

Please go to the image description page and edit it to include a fair use rationale. Using one of the templates at Fair use rationale guideline is an easy way to insure that your image is in compliance with Wikipedia policy, but remember that you must complete the template. Do not simply insert a blank template on an image page.

If there is other fair use media, consider checking that you have specified the fair use rationale on the other images used on this page. Note that any fair use images lacking such an explanation can be deleted one week after being tagged, as described on criteria for speedy deletion. If you have any questions please ask them at the Media copyright questions page. Thank you.

Logo?
The logo was removed by a bot. I'm new to this can we put it back? I think most projects free or not (the microsoft page for example) have their logos...why not sendmail? Wubrgamer (talk) —Preceding comment was added at 19:15, 14 May 2008 (UTC)

Requested move
Sendmail → ? – sendmail the open source mail transfer agent and Sendmail, Inc. the company are related but wholly separate topics. According to Wikipedia's naming guidelines, titles are those that readers are likely to search for. Those searching for the company may only type 'Sendmail' (vs. 'Sendmail, Inc.') and then be taken to the page about sendmail the MTA. Wmoses2 (talk) 18:37, 24 January 2013 (UTC)

Most people looking up sendmail are looking for the MTA not the company. There is a link in the first line of the article to Sendmail, Inc.. Leave the this article as it is. Robert.Harker (talk) 19:09, 24 January 2013 (UTC)

Postfix sendmail
Postfix has a client application also named sendmail. Some readers may come to this Sendmail page looking for information about this client app. I'm not sure how to but suggest inclusion of a link to the Postfix page. Possibly to the Architecture section which contains an image that shows how the postfix sendmail works with the postfix server. See Postfix (software)
 * Such a link can easily be included next to the disambiguation link to Sendmail, Inc. at the top, using the same template, but since the target article text does not even mention Postfix sendmail and even includes a mention of the Sendmail described here, it seems like a dubious idea at this time.--Reseletti (talk) 10:38, 1 December 2020 (UTC)
