[SOLVED] Problems sending mails

[williammr]

Hi,

When i send an email i receive this message on my logs files:

Jan 21 16:31:30 correo postfix/qmgr[25507]: AABB02482F8: from=<myusername@mydomain.com>, size=1867, nrcpt=1 (queue active)
Jan 21 16:31:30 correo postfix/qmgr[25507]: 77BDF248316: from=<>, size=4255, nrcpt=1 (queue active)
Jan 21 16:31:35 correo postfix/smtp[1650]: AABB02482F8: lost connection with yahoo.com[216.109.112.135] while receiving the initial server greeting

My domain receive emails but i can't send email to any domain.

Any idea!!!

My DNS works fine, zimbra receive emails, every email i send is marked as deferred.

If you need more information, just ask me

Thank you for your time!!!

What kind of internet connection do you have? My home internet connection blocks port 25. (btw I really hate AT&T DSL)

Can you telnet to an SMTP server on the internet? You should get a 220 response when you telnet to port 25.

I'm assuming that you can send emails within the Zimbra server itself. What version of Zimbra do you have?

Hi,

I solved this problem changing some things in the Admin Console:

In General Configuration -> MTA Tab -> Authentication Section change this settings:

- Check the option Activate Authentication
- Uncheck the option Only TLS Authentication

In General Configuration -> MTA Tab -> Network change this settings:

- Check the option Activate DNS Queries

And thats all, my email server starts to send and recieve emails. And everything is working fine.

Thank you
