Could not complete sender verify callout

SYMPTONS:

When you attempt to send mail to someone the recipient never
receives the mail. The mail is eventually bounced back to you with an
error similiar to those below

550 Could not complete sender verify callout

550 Sender verify failed

CAUSE:

Some mail servers attempt to validate the sending email address
before accepting any mail. They do this by issuing a RCPT TO command to
the sending mail server with the senders email address. If the sending
mail server responds with a 250 command then they know the sending
email address exists and therefore accept the message.

If they are unable to verify the sender then they issue a response similiar to that above.

The main reason that the sender verify can fail is because the
remote mail server does not conform to standard RFCs. They issue a RCPT
TO command to our server but do not wait long enough for a response. RFC 2821 #4.5.3.2
states that the mail server should wait up to 5 minutes for a response.
As part of our email harvesting protection system we sometimes perform
a delay on incoming connections.

RESOLUTION:

Contact the recipient by other means and ask them to whitelist your address.

and/or

ask the recipient to ensure their mail server complies with RFC 2821 #4.5.3.2.

The IEEE 802.11 standard limitation makes it impossible for wireless cards in station mode to work as expected when bridged. That means that if you need to create a bridge, you should not use station mode on that machine. In case you need a bridge on a wireless station, use station-wds mode (may only be used in the AP supports WDS). Bridging on the AP side works fine

pantesan pernah dibikin pusing case seperti ituh, that case is

(senao AP) <—> (mikrotik Client) + bridge eth <—-> (client)

Hasilnya dari client kaga mau sampai di Senao AP. Busyet dah, gw pikir waktu itu "nih mikrotik kok suseh diatur yes, enakan pake senao aja". But, waktu itu akhirnya gw ambil solusi ganti mode, senao client and mikrotik AP mode. Lancar.
