ISP blocking port 25!!!
After 2 somewhat successful years of using zimbra, my isp decided to block port 25 on my connection. Is there a way around this? If so, please point me in the right direction.
Thanks,
Storm

One solution would be to rent a virtual server somewhere and run a Zimbra MTA server there. I don't have enough experience with the virtual host providers to recommend one over another, but I've seen that they are relatively inexpensive.

Storm[/QUOTE]Do you mean Inbound, Outbound or both? If it's Outbound then relay through their servers. If it's inbound then use a service such as the one from dyndns.org that will forward mail to an alternate port on your Zimbra server (details in the forums/wiki on how to change the port). Obviously if it's both then dyndns.org also have a relay facility for Outbound mail (I believe), there are other suppliers of such services.

Yes, inbound and outbound. I looked at dyndns and I guess if I want it working, I will need to drop $40 on it.
Thanks, for the advice.

I don't think anyone provides that service for free but do search around, as I said, there's other providers that do it.

I just ran into this issue and found a solution that worked. I edited the /opt/zimbra/postfix/conf/master.cf fileand uncommented the following line:
#submission inet n - n - - smtpd
then retart the smtp server
This tells the zimbra server to listen on port 587 (Authenticated smtp) and it worked fine here.

Yeah... I use Comcast at home as well, and I've been using No-Ip's Mail Reflector. I actually started using Mail Reflector when I was living in an area that was provided by Opt. Online. I just haven't dropped the service since because:
1) It works.. Quite well....
2) It provides me with a backup storage of email if/when my own server is down (like most recently when I lost an HD and had to recover from a backup).
It costs $40 a year though. That's the only downside to it.

Perfect. Exactly what I needed. I wonder where the right place is to put this on the wiki.
