Re: [expert] Sending mail throughout several smtp servers?
francisco, i'm not surprised that you can't use either smtp server while not authenticated with it i.e. not logged on the network it's physically attached to, this is to prevent spamming activity, you may log onto your uni network from home but the smtp server will see that you are 'outside' the uni network and disallow relaying from you, all isps i know of do the same, however, why do you wish to do this? surely either server will relay all your mail whatever the 'sender' address as long as your are connected to it's local network? the windows prog you mention is probably just a windows alternative to stuff like postfix or sendmail, i use postfix on my linux box, that way i don't have to worry about smtp servers at all (except where outblaze think i'm a spammer cos i deliver direct!) bascule On Sunday 07 Sep 2003 3:12 pm, Francisco wrote: > I have two e-mail accounts, one at home ([EMAIL PROTECTED], using the > smtp.ono.com server) and other at work ([EMAIL PROTECTED], using the > correo.um.es server).

If you don't have smtp delivery then fetchmail will pull mail from POP3 mailboxes and deliver it to your Linux mail system. Fetchmail may also send mail to your ISP with SMTP, I don't know, I don't use it myself. If not then you can use postfix for that. A domain name is something you should look into though, it is not expensive, (under GBP7 for .org.uk, for two years,) and even without postfix etc it can make your life a lot easier if you want to change ISPs. For example 123-reg.co.uk, (and I think, lots of others,) offer mail redirection. so you just redirect [EMAIL PROTECTED] to [EMAIL PROTECTED] When you change isp, you just change the redirect, and your email address stays the same. -- Richard Urwin Want to buy your Pack or Services from MandrakeSoft?

My understanding is that my isp can block (it doesn't, some do) port 25 at it's router/firewall so that my machine cannot make a smtp connection to any other machine outside of its network. This forces me to use their smtp server for all outgoing mail. Also, Roadrunner blocks port 25 connections from dynamic ip address ranges, so I cannot send a message to someone using roadrunner using postfix. I have to use my isp's smtp server for that too. -- /g "Outside of a dog, a man's best friend is a book, inside a dog it's too dark to read" -Groucho Marx Want to buy your Pack or Services from MandrakeSoft?

There has been some talk on the list about your address going into a blackhole list if you mail directly, anyway. -- Richard Urwin Want to buy your Pack or Services from MandrakeSoft?

One server's incoming is another server's outgoing... Outgoing mail is generally addressed to port 25. Some ISPs block outgoing port 25 to everything except their own email servers to cut down on spam generated from within their networks. Some ISPs block incoming port 25 to prevent their customers from running their own intentional or accidental mail servers. Want to buy your Pack or Services from MandrakeSoft?

If you use POP3 to receive > then it wont affect you. Untrue. Some ISPs block outbound port 25 to any systems other than their own SMTP servers. This will prevent direct mail delivery by Postfix, and require the use of the ISP's server as a relay host, or a tunneling setup via another host outside of the provider's network. We have the recent innovation in Wincrap viruses, self-contained SMTP agents, to thank for this development, IMHO. While spammers have been an increasing burden on ISPs, no doubt, few Windoze users had been running mail servers that they could co-opt, and spam was therefore more of an inbound problem for the vast majority of operators; now that each new virus-attacked host becomes a direct spam source as well - as part and parcel of the infection process - some ISPs are becoming more proactive in enforcing their AUP/TOS by blocking outbound 25; as this new policy *does* somewhat inhibit the spread of the viruses in question, the ISPs are not getting a lot of flak over it from the bulk of their client base, either. -- Bill Mullen [EMAIL PROTECTED] MA, USA RLU #270075 MDK 8.1 & 9.0 "Giving money and power to the government is like giving whiskey and car keys to teenage boys." - P.J.
