Sending outgoing mails through specified interface.

Hi Dima,

Configure a Multipath rule. Refer: https://www.sophos.com/en-us/support/knowledgebase/115322.aspx

Note: Before saving the multipath rule, click on the advance tab in the multipath configuration box and select "Skip rule on interface error". 

Thanks

Hi sachingurung,

Thanks for your answer.

I think its correct for sending without SMTP relay on Sophos, directly to the internet from Exchange server.

I used this configuration without relay, but I'll try.

Thanks.

best practise is to use the sophos for outgoing mails too.

so sophos will scan all outgoing mails too. also you see the sended mails in the sophos logs which makes life easier for ya in case of supporting..

This how it works in my config.

But the problem is how to configure sending from specific interface.

 sachingurung solution not work in this case........... 

i use a HA-Cluster sophos SG310 at work with 4 internet-lines attached to it.

i send e-mail only with one line cause of mx-records / anti-spam solutiions.

i use the described multipath-rule to send my mails over the specific interface and it works without any problems.

rule have to look like this:

source: any

service: email_Messaging (default service-group by sophos)

destination: any

ltf. persistence: by interface

BInd Interface: the_interface_you_will_use_for_mail

Advanced: set skip rule......

save it then get it active...

This is my config:

and its not working......... 

Its worked before I'am starting to send mails through Sophos SMTP relay

This is my config:

and its not working.........

change the source to any and test it again please. think if you use the sophos as outgoing relay it sends with its own adresses..
