The original assumption seems to have been that SquirrelMail would only ever be accessed via the domain for which you are serving mail. That's not all that bad of an assumption, although I think it probably is a bad idea to use a value that essentially comes from what the user typed into the address bar for an internal process. > And in that case is > there anyway to configure away this behavior? > > This is my first attempt ever to set up my own mail server and not > very experienced in Apache but I have tried a few solutions found on > the net: > * To set it using Server Settings/Domain using squirrelmail-configure > * Set ServerName in the Apache config > Both without success. > * Using mod rewrite in Apache > Seems to work, but has the drawback that I must rewrite to the > external DNS name to always get the same HELO URL. > > I have also checked the source and the problem seems to be in > “Deliver_SMTP.class.php” where $_SERVER['HTTP_HOST'] is used if > available.

I will look at possibly changing this or allowing it to be configurable. I think defaulting first to the $domain value seems appropriate. HOWEVER, I think you should reconsider your network design. Why isn't your webmail available by the same domain name no matter where you are? Why would you make yourself or your users have to remember different addresses to access such things depending on where they are? Not user friendly IMO. > The reason I like to get the same HELO URL is that it seems to make it > a bit easier to use restrictions in postfix and to check the mail logs > for unwanted activities. Create a special webmail-only port in your MTA that will allow you to do whatever you want with mail coming from webmail instead of forcing your users to have to do gymnastics to satisfy your internal requirements. -- Paul Lesniewski SquirrelMail Team Please support Open Source Software by donating to SquirrelMail! http://squirrelmail.org/donate_paul_lesniewski.php ------------------------------------------------------------------------------ RSA(R) Conference 2012 Mar 27 - Feb 2 Save $400 by Jan. 27 Register now! http://p.sf.net/sfu/rsa-sfdev2dev2 ----- squirrelmail-users mailing list Posting guidelines: http://squirrelmail.org/postingguidelines List address: squirrelmail-users@xxxxxxxxxxxxxxxxxxxxx List archives: http://news.gmane.org/gmane.mail.squirrelmail.user List info (subscribe/unsubscribe/change options): https://lists.sourceforge.net/lists/listinfo/squirrelmail-users
