Am trying to reply to e-mails but some just will not go through eg to btinternet accounts, wanadoo accounts, most are not affected error response is:-

 

550 RCPT: Relaying not allowed - please use SMTP AUTH

 

 

Have contaced my ISP who cant help, no surprise there!

 

Am using outlook 2003

 

anybody have any ideas?

[Guest jay_con]

Not familiar with outlook. Are you using the correct SMTP settings as directed by your isp.

[melpen]

Yes,

 

Have just subscribed to 4 isp`s smtp setting changed in each case, all with same prob. Also changed to Outlook Express with same results.

 

The fault lays within My software, but where?

 

Can anybody recommend a good e-mail package to work with firefox & XP Pro?

[Guest jay_con]

I use xp pro and have always used OE with no problem whatsoever. I undersatnd that mozilla do a good mail browser but my guess is you will encounter the same smtp problems.

 

Haqve you tried ticking the authentication box in tools- accounts - properties - servers ???

[jeepster]

mozilla thunderbird is excellent, but probably wont solve this problem. who is your email provider, i had a similar problem when i used my own domain emails without having setup an smtp service (BT broadband used to provide this as part of their service but now no longer do)

[melpen]

Used 4 different ones last night, all with same results, at mo using tiscili( i only have dialup)

 

Is there something in registry gone wrong?

[melpen]

Sorted

 

Very complicated!

 

Because i have no Broadband where I live, I have satellite download at 16MB max, & using 56k dialup as my back channel.

Now this is where it gets complicated, i recieve my e-mails via satellite, therefore my satellite ISP pulls my e-mails from my dialup ISP using HTTP tunneling to its e-mail server in Berlin.

So when i was trying to send an e-mail i was sending it through the dialup ISP to be routed to my ISP in berlin. I THINK

 

Anyway upshot is when sending e-mails i have to shutdown sat software, & it works

[Guest jay_con]

Now that is complicated.
