    Just got back from Germany, where I could send mails fine, to Mexico where I could send mails fine in the past but not anymore.

    Every account now tells me it can't send mail from this server. Getting mails is fine as is everything else internet related.

    - Checked account settings
    - Accounts over webmail work
    - Accounts over different networks work as they did in Germany over my network

    My guess is it's either a change in the network here in Mexico or the ISP has changed something, the first I'll be able to check out in an hour or so the other I don't know.

    Any other ideas why this isn't working?

    When you say that you checked the account settings I assume you mean that you checked to make sure that they match the information given you by your new Mexican ISP. Is that true?

    Well, the thing is that there has been no change in ISP and it has worked with the same equipment and the same ISP like 4 weeks ago. Now it doesn't anymore and the only thing that really made sense is the changes in the router but the router has been untouched. So maybe the ISP made some changes without telling? I'll setup the router from scratch just to make sure though.

    Yeah, and recheck the SMTP Server settings with the ISP and your email client. :)

    Could be the ISP changed SMTP server names while you were gone, could be they have implemented additional security, could be they are disallowing SMTP connections from outside their network (such as, using a Cable or DSL connection from one company, and trying to send mail on a different company's mailserver.)

    True. Also, play around with SSL settings (on/off) and the authentication settings.

    I'm hearing that you were in Germany where everything was working fine, you arrive back in Mexico, internet is ok but the outgoing mail is coming back with that message to 'try a different server.' Right? I want to get that clear to understand what's going on.

    If you are using mail, I find that if I try to send the message that wouldn't go out, it will never work and clog up my system. I click the button that says 'edit this message,' copy, create a new mail, paste, send..

    By chance, do you have a gmail account you could test it out on? I use gmail as my main outgoing message server because it is quite stable and not so temperamental. If you want gmail, PM me.

    My network resently blocked out port 25 - the regular SMTP port and suddenly I found me self being unable to send email but the solution was to use my ISP's SMTP server instead of my "email provider's"... Maybe it's the same for you!?
    Also using SSL will also work if your "email provider" support SSL because SSL runs through port 465!
