I added a setenv.sh file in /usr/share/tomcat7/bin, allowing to set the System property -Djava.net.preferIPv4Stack=true, in order to not use ipv6, that is problematic.

The mails are still sent in ipv6, I don't know why, as setenv.sh is corectly executed. Definitly something server-side. Mail client configured to send ipv6 only?

Some mails are accepted, some are rejected.

The postfix/mail server uses all protocols by default. I prefer not to change that and keep default postfix behavior. Maybe future versions of Postfix will address some of the problems.

To solve the issue with gmail, I have found a way to disable ipv6 when sending to gmail (http://postfix.1071664.n5.nabble.com/disable-ipv6-when-sending-to-gmail-td60672.html).

I don't know how to satisfy all gmail ipv6 requirements (https://support.google.com/mail/answer/81126?p=ipv6_authentication_error&rd=1#authentication) and don't know if UNIL does: if I solve that, maybe it will fail with unil when sent by a machine and not by a user.

I have tested on command line with gmail, yahoo, unil and sib e-mail addresses and all works for me on bioinfo.unil.ch.

Could you test it in topanat?

And maybe with the trick I used setenv.sh can be removed.

I have just send plenty of e-mails to gmail, and some work, some don't.

So, for now, bioinfo.unil.ch sends all e-mails in ipv4 but this is not ideal nor good for future updates and protocols. Will try https://powerjpm.info/dossiers/installer-un-serveur-postfix-en-ipv6-sous-ubuntu-conforme-aux-attentes-de-gmail/ on my own machine.

Can you test in topanat? With or without setenv.sh?

I tried 4 analyses with mails correctly sent, using TopAnat on bgee.org. I remove the setnenv.sh.

I keep this issue open, with a lower priority, until you completely fix the ipv6 problems.
