Proper DNS hostnames to use for mail, ssh, ftp, etc.

Some of you may be having difficulties connecting if you are using a non-standard hostname for connecting to your e-mail or through ssh or ftp.

These are the hostnames we'd like you to use so that you are well supported:

E-mail

  • Outgoing SMTP: smtp.suso.com
  • Incoming IMAP: imap.suso.com
  • Incoming POP3: pop3.suso.com
  • Webmail: webmail.suso.com

If you are still using mail.suso.org, that will currently work ok, but we will no longer renew the SSL certificate associated with that hostname, so you may have trouble if you use SSL or TLS encryption to connect to that hostname for your e-mail.

SSH/SCP or FTP

  • Please use the hostname of your website or use yourusername.suso.org.

MX server

  • If you are managing your own DNS and have been pointing your MX record to mail.suso.org or arvo.suso.org, you will need to point that to mercury.servers.suso.org. We may be changing this later, but we'll contact you when we do.

If you have questions about another service and what the proper hostname is, please let us know.

Webmail system upgraded

We just finished upgrading the Squirrelmail webmail installation to the latest version. Please let us know if you notice any issues. Our testing shows that things are working ok.

We're planning on adding a few other webmail options to the mix in the coming weeks. We've been hesitant to do so because we wanted to finish the migration to LDAP and the new shared user server (Dorabella) first.

Now for some history.

Many years ago Suso had an option for setting which webmail software you wanted to use and keep that preference saved. It worked great, but unfortunately the webmail software that we were using at the time (Jawmail) was not maintained and was no longer compatible with our system after a certain point. Such has been the way with webmail systems over the past decade. Some people criticize our lack of webmail options, but you have to see it from our point of view. Suso actually was one of the first and few providers to offer a webmail system all the way back in 1999. I think Aeromail was the first option we went with. I modified it quite a bit to work better with our user preferences and also offer some extra options and ended up releasing it as a forked version called Oreamail. Aeromail didn't last very long and we ended up going with Jawmail for a while. Then Squirrelmail came along. You have to understand that over the last 10 years, webmail systems have come and gone and its been difficult to find one as well maintained and as stable as Squirrelmail. So that is the reason why we've stuck with it. Roundcube is often quoted as an alternative option and we actually tried out Roundcube on the first day it was available, but it had a lot of bugs to work out. Now it finally has something of a stable version. THere are also a few others like AfterLogic and Hastymail that we will try.

Virtual machine RAM defaults increased by 33% and new Fast Swap feature

In celebration of Suso's 12.69315th year anniversary and just because we are so nice, we've increased everyone's VPS hosts' RAM by 33%. If you had 256MB before, you will have 340MB now, if you had 512MB before, you will have 680MB now and so on. Along with this increase we've implemented a new feature we developed called Fast Swap. Hopefully you won't need it, but if you do start to use virtual memory, it will be faster than normal disk based swap and shouldn't interfere with other customer's VPSes as much.

You should have already been contacted about making these changes and we have already rebooted most of the VMs. If you haven't yet, please let us know when a good time to reboot yours would be. Thanks and enjoy.

Update: The upgrade has been a success and as you can see from the graph below of the load average on one of the Xen hosts, it is helping tremendously.

The load average on the host has gone down significantly, showing that there is less disk contention.

Missing email from this month?

If you are missing email from between June 13th and June 15th, you should check your spam folder as it might be located there. If you don't see your spam folder, you may need to subscribe to it in your mail client.

We made an upgrade to our spam filter software on June 13th and there was a default scoring for a rule that was set too high. We fixed this on the 15th, but there were some legitimate messages that would have been marked as spam. Sorry for the inconvenience.
